Description

Technical Field

[0001] This invention relates to the field of gear processing technology, and in particular to a gear break-in control circuit and control method. Background Technology

[0002] With the rapid development of society, users are increasingly using plastic gears, hoping to meet normal usage requirements while minimizing malfunctions. This places higher demands on the processing of plastic gears. Traditional plastic gear processing involves a single-stage break-in process after injection molding to remove burrs. This method has significant drawbacks, as the single-stage break-in method is not very effective at removing burrs. In other words, this method, relying on only a single break-in stage, results in limited functionality of the gear break-in circuitry. Summary of the Invention

[0024] Obtain a preset threshold time value and detect whether the threshold time value matches the time information;

[0025] If the threshold time value matches the time information, the working state is that the first self-locking relay enters the self-locking state;

[0026] If the threshold time value does not match the time information, the working state is that the first self-locking relay enters the non-self-locking state.

The motor break-in control circuit is also electrically connected to the motor mode selection circuit. The switch control circuit selects different break-in modes for the mode selection circuit. Based on these modes, the motor break-in control circuit operates the motor to break in the gears. This avoids the problem in existing gear break-in devices where a single break-in method is used to remove burrs. This gear break-in control circuit not only ensures the accuracy of the break-in mode by controlling different break-in modes through the motor break-in control circuit, but also expands the functionality of the gear break-in circuit by providing a motor mode selection circuit.

[0037] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0040] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0041] This invention proposes a gear break-in control circuit.

[0042] In one embodiment of the present invention, such as Figure 1 The diagram shows a structural schematic of one embodiment of the gear break-in control circuit. The gear break-in control circuit includes a power supply circuit 10, a switch control circuit 20, a motor break-in control circuit 30, and a motor mode selection circuit 40.

[0043] The power supply circuit 10 includes a first power supply 11 and a second power supply 12. The first power supply 11 is electrically connected to the switch control circuit 20, the motor break-in control circuit 30, and the motor mode selection circuit 40. The second power supply 12 is connected to the relay circuit 50 in the switch control circuit 20, the motor break-in control circuit 30, and the motor mode selection circuit 40. The switch control circuit 20 is electrically connected to the motor break-in control circuit 30 and the motor mode selection circuit 40. The motor break-in control circuit 30 is electrically connected to the motor mode selection circuit 40.

[0044] In this embodiment, the power supply circuit 10 provides a first power supply 11 to power the switch control circuit 20, the motor break-in control circuit 30, and the motor mode selection circuit 40, and simultaneously provides a second power supply 12 to power the various relays in the switch control circuit 20, the motor break-in control circuit 30, and the motor mode selection circuit 40, enabling them to operate normally. The switch control circuit 20 is electrically connected to the motor break-in control circuit 30 and the motor mode selection circuit 40. By controlling the conduction of different switches in the switch control circuit 20, the motor mode selection circuit 40 can select the corresponding mode. This also puts the motor break-in control circuit 30 into operation. Through the electrical connection between the motor break-in control circuit 30 and the motor mode selection circuit 40, different motor break-in controls can be implemented according to different modes, providing different modes for the gear break-in of the motor and enriching the gear break-in modes.

[0045] In one embodiment, reference is made to... Figure 2As shown, the power supply circuit 10 also includes a first power supply module 24V power supply, a second power supply module PLC power supply, a power switch SB, and a fuse FR;

[0046] One end of the power switch SB is connected to the neutral line A. The end of the power switch SB away from the neutral line is connected to one end of the fuse FR. The end of the fuse FR away from the power switch SB is connected to one end of the first power supply module 24V power supply and one end of the second power supply module PLC power supply. The end of the first power supply module 24V power supply away from the fuse FR and the end of the second power supply module PLC power supply away from the fuse FR are connected and then connected to the live line L. The first power supply module 24V power supply processes and outputs DC voltage as the first power supply 11, and the second power supply module PLC power supply processes and outputs AC voltage as the second power supply 12.

[0047] In this embodiment, the first power supply module 24V power supply and the second power supply module PLC power supply in the power supply circuit 10 provide the entire gear break-in control circuit with a 24V DC voltage and an AC voltage to enable the PLC to work normally. The fuse FR is used to protect the entire circuit and prevent current or voltage overload. The first power supply module 24V power supply and the second power supply module PLC power supply can output the corresponding voltage according to the user's needs to enable the circuit to work normally.

[0048] In one embodiment, reference is made to... Figure 3 As shown, the switch control circuit 20 includes a first indicator light 011ZSD, a second indicator light 013ZSD, a third indicator light 014ZSD, a first switch SB0, a second switch SB1, a third switch SB2, a fourth switch SB3, a first PLC output point *Y0, a first PLC built-in switch Y0, a second PLC output point *Y1, a second PLC built-in switch Y1, a first intermediate relay *KM0, and a second intermediate relay *KM1;

[0049] One end of the first PLC built-in switch Y0, one end of the second PLC built-in switch Y1, one end of the first switch SB0, and one end of the second switch SB1 are connected to the negative terminal of the first power supply 11. The end of the first switch SB0 away from the negative terminal of the first power supply 11 is connected to one end of the fourth switch SB3. The end of the fourth switch SB3 away from the first switch SB0 is connected to one end of the first PLC output point *Y0. The end of the first PLC built-in switch Y0 away from the negative terminal of the first power supply 11 is connected to one end of the first indicator light 011ZSD and one end of the first intermediate relay *KM0, respectively. The end of the second switch SB1 away from the negative terminal of the first power supply 11 is connected to one end of the third switch SB2 and one end of the fourth switch SB3. The end of the fourth switch SB3 away from the second switch SB1 is connected to one end of the second PLC output point *Y1. The end of the PLC built-in switch Y1 furthest from the negative terminal of the first power supply 11 is connected to one end of the second indicator light 013ZSD and one end of the second intermediate relay *KM1. The end of the third switch SB2 furthest from the second switch SB1 is connected to one end of the third indicator light 014ZSD. The positive terminal of the first power supply 11 is connected to the end of the first indicator light 011ZSD furthest from the first PLC built-in switch Y0, the end of the second indicator light 013ZSD furthest from the second PLC built-in switch Y1, the end of the third indicator light 014ZSD furthest from the third switch SB2, the end of the first PLC output point *Y0 furthest from the fourth switch SB3, the end of the second PLC output point *Y1 furthest from the fourth switch SB3, the end of the first intermediate relay *KM0 furthest from the first PLC built-in switch Y0, and the end of the second intermediate relay *KM1 furthest from the second PLC built-in switch Y1.

[0050] In this embodiment, when the first switch SB0 and the fourth switch SB4 are simultaneously turned on, the first PLC output point *Y0 is determined to be working. The working of the first PLC output point *Y0 will turn on the first PLC built-in switch Y0, which will illuminate the first indicator light 011ZSD and simultaneously activate the first intermediate relay *KM0, correspondingly turning on the first intermediate relay switch KM0. Therefore, the steps for the second switch SB1 and the fourth switch SB4 to control the second indicator light 013ZSD and the second intermediate relay *KM1 are the same as described above. The first indicator light 011ZSD, the second indicator light 013ZSD, and the third indicator light 014ZSD represent the selection of modes 011 / 013 / 014, respectively. Modes 011 and 013 correspond to the first motor circuit and the second motor circuit described below, respectively. The difference between 011 and 013 in terms of motor forward and reverse rotation lies mainly in the wiring and the corresponding control program, while 014 can only achieve one direction of motor rotation. Since mode 014 does not have dual-direction control, it is unnecessary to connect to the PLC output point. The gear break-in control circuit can be directly controlled by the second switch SB1 and the third switch SB2 to achieve mode 014 and illuminate the third indicator light 014ZSD. The relationship between *Y0 and Y0 is that *Y0 is a component similar to a control device, while Y0 refers to the internal or associated switch of that control device. When *Y0 is normally conducting, the corresponding Y0 is equivalent to a closed switch; when *Y0 is not conducting and not in operation, the corresponding Y0 is equivalent to a normally open closed switch. The working principle of the subsequent *T0 and T0 series (T0, T1, T2, T3), KM0 and *KM0 series (KM0, KM1, KM3, KM4), and *M0 and M0 (M0, M1) series is the same as that of *Y0 and Y0, which is the same as the control principle of a relay. The switch control circuit 20 is used to implement the circuit of the mode indicator light and select the corresponding break-in mode to control the motor mode selection circuit 40.

[0051] The first switch SB0 and the second switch SB1 are first rocker switches, the third switch SB2 and the fourth switch SB3 are second rocker switches, and the third switch SB2 is a dual-control reverse switch.

[0052] In this embodiment, the first switch SB0 and the second switch SB1 are first rocker switches, and the third switch SB2 and the fourth switch SB3 are second rocker switches. These two rocker switches are equivalent to two selector switches, providing four selection modes and enabling selection of different modes. Furthermore, the third switch SB2 is a dual-control reverse switch. This means that when the third switch SB2 in the switch control circuit is open, the corresponding third switch SB2 in the motor break-in control circuit is closed; their on / off states are opposite. This achieves two different control directions. The function of the third switch SB2 is the 014 mode, because 014 only has one rotation direction, while the third switch SB2 in the motor break-in control circuit controls both rotation directions. Therefore, when in 014 mode, dual rotation direction control is not required, so the third switch SB2 in the motor break-in control circuit is closed. This achieves control of the single-direction 014 mode and uses rocker switches to achieve the desired effect while reducing the number of switches used.

[0053] In one embodiment, reference is made to... Figure 4 As shown, the motor mode selection circuit 40 includes a first intermediate relay switch KM0, a second intermediate relay switch KM1, a third intermediate relay switch KM3, a third intermediate relay *KM3, a fourth intermediate relay *KM4, a third PLC built-in switch Y3, a fourth PLC built-in switch Y4, a fourth indicator light ZSD0, a first motor circuit, and a second motor circuit.

[0054] The negative terminal of the first power supply 11 is connected to one end of the third intermediate relay switch KM3, one end of the fourth indicator light ZSD0, one end of the third PLC built-in switch Y3, and one end of the fourth PLC built-in switch Y4. The end of the third PLC built-in switch Y3 furthest from the negative terminal of the first power supply 11 is connected to one end of the third intermediate relay KM3. The end of the fourth PLC built-in switch Y4 furthest from the negative terminal of the first power supply 11 is connected to one end of the fourth intermediate relay KM4. The other end of the third intermediate relay switch KM3 is connected to one end of the first intermediate relay switch KM0 and one end of the second intermediate relay switch KM1. One end is connected, the end of the first intermediate relay switch KM0 away from the third intermediate relay switch KM3 is connected to the output terminal of the first motor circuit, the end of the second intermediate relay switch KM1 away from the third intermediate relay switch KM3 is connected to the output terminal of the second motor circuit, and the positive terminal of the first power supply 11 is connected to the end of the fourth indicator light ZSD0 away from the negative terminal of the first power supply 11, the input terminal of the first motor circuit, the input terminal of the second motor circuit, the end of the third intermediate relay KM3 away from the third PLC built-in switch Y3, and the end of the fourth intermediate relay KM4 away from the fourth PLC built-in switch Y4.

[0055] In this embodiment, after the switch control circuit 20 selects the switch mode, it controls the motor mode selection circuit 40 to select the mode. In the motor mode selection circuit 40, the third PLC built-in switch Y3 and the fourth PLC built-in switch Y4 are controlled by the third PLC output point *Y3 and the fourth PLC output point *Y4 in the motor break-in control circuit 30. That is, when the third PLC output point *Y3 is working, the third PLC built-in switch Y3 in the motor mode selection circuit 40 is closed, and the motor rotates forward through the third intermediate relay *KM3; when the fourth PLC output point *Y4 is working, the fourth PLC built-in switch Y4 in the motor mode selection circuit 40 is closed, and the motor rotates in reverse through the fourth intermediate relay *KM4. Furthermore, when the power supply circuit 10 provides the first power supply, it directly illuminates the fourth indicator light ZSD0, indicating that power is on. Furthermore, when the first row control switch SB4 in the motor break-in control circuit 30 is closed, it is equivalent to the third intermediate relay switch KM3 being closed. Based on the switch selection in the previous switch control circuit 20, it can be determined whether the 011 motor circuit or the 013 motor circuit is activated. For example, when the switch control circuit 20 selects to activate both the first switch SB0 and the fourth switch SB4, the first indicator light 011ZSD will be illuminated, and the first intermediate relay *KM0 will operate, thus activating the first intermediate relay switch KM0, and consequently activating the 011 motor circuit. Therefore, the process of activating the 011 motor circuit is similar to the above. While the timing of 013 and 011 may differ, the actual difference lies in the wiring of the control circuit. The 014 mode only has single-rotation capability, so it does not necessarily need to be connected to the circuit; it can be directly controlled by the motor break-in control circuit 30 after the switch control circuit 20. This allows for the selection of different modes and the control of forward and reverse motors.

[0056] In one embodiment, reference is made to... Figure 5 As shown, the first motor circuit includes a first motor DJ011-1, a second motor DJ011-2, a third motor DJ011-3, a fourth motor DJ011-4, a fifth motor DJ011-5, a sixth motor DJ011-6, a seventh motor DJ011-7, an eighth motor DJ011-8, a ninth motor DJ011-9, and a fourth intermediate relay switch KM4;

[0057] One end of the first motor DJ011-1, one end of the second motor DJ011-2, one end of the third motor DJ011-3, one end of the fourth motor DJ011-4, one end of the fifth motor DJ011-5, one end of the sixth motor DJ011-6, one end of the seventh motor DJ011-7, one end of the eighth motor DJ011-8, and one end of the ninth motor DJ011-9 are connected to the output terminal of the first motor circuit. The ends of the first motor DJ011-1, the second motor DJ011-2, and the third motor DJ011-3 that are furthest from the output terminal of the first motor circuit are also connected. One end of the fourth motor DJ011-4, the end of the fifth motor DJ011-5, the end of the sixth motor DJ011-6, the end of the seventh motor DJ011-7, the end of the eighth motor DJ011-8, and the end of the ninth motor DJ011-9 are respectively connected to the output terminal of the first motor circuit and one end of the fourth intermediate relay switch KM4. The end of the fourth intermediate relay switch KM4 that is away from the motor is connected to the output terminal of the first motor circuit.

[0058] In this embodiment, the first motor circuit (011 motor circuit) and the second motor circuit (013 motor circuit) have the same configuration; only the program that the motor needs to execute is different. Figure 5 The motors 3-7 are omitted in the text. The main point is that the motor rotates normally in the forward direction when the fourth intermediate relay switch KM4 is not activated, and rotates in the reverse direction when the fourth intermediate relay switch KM4 is activated. Another point is that the 014 mode does not require the fourth intermediate relay switch KM4, therefore the 014 motor circuit is not needed. Furthermore, the definition of one end and the other end of the motor needs to be defined according to the positive and negative terminals and wiring requirements; it only indicates the position of external components, without defining the positive and negative terminals of the electrical components. Moreover, the first row control switch SB4 in the motor break-in control circuit 30 controls one row of 9 motors, while this application contains 6 switches identical to the first row control switch SB4, thus enabling the control of 54 motors in 6 groups. The control principle of each row is the same as that of the motor break-in control circuit 30; only different row control switches need to be activated for control. Therefore, this application can achieve simultaneous gear break-in at 54 positions, greatly improving the efficiency of gear break-in.

[0059] In one embodiment, reference is made to... Figure 7As shown, the motor break-in control circuit 30 includes a forward break-in circuit and a reverse break-in circuit. The forward break-in circuit includes a first control switch SB4, a first time relay switch T0, a second time relay switch T1, a third time relay switch T2, a fourth time relay switch T3, a first self-locking relay *M0, a third PLC output point *Y3, a first time relay *T0, and a second time relay *T1.

[0060] The negative terminal of the first power supply 11 is connected to one end of the first control switch SB4, one end of the first self-locking relay switch M0, one end of the third time relay switch T2, and one end of the first time relay switch T0, respectively. The end of the first control switch SB4 furthest from the negative terminal of the first power supply 11 is connected to the end of the first self-locking relay switch M0 furthest from the negative terminal of the first power supply 11, the end of the third time relay switch T2 furthest from the negative terminal of the first power supply 11, and one end of the fourth time relay switch T3, respectively. The end of the fourth time relay switch T3 furthest from the first control switch SB4 is connected to one end of the second time relay switch T1, and the end of the second time relay switch T1 furthest from the fourth time relay switch T3 is connected to one end of the first self-locking relay switch M0. The end of the first self-locking relay switch M0 away from the negative terminal of the first power supply 11 is also connected to one end of the second time relay switch T1. The end of the second time relay switch T1 away from the first self-locking relay switch M0 is also connected to one end of the first time relay *T0. The end of the first time relay switch T0 away from the negative terminal of the first power supply 11 is connected to one end of the second time relay *T1 and one end of the third PLC output point *Y3. The positive terminal of the first power supply 11 is connected to the end of the third PLC output point *Y3 away from the first time relay switch T0, the end of the first time relay *T0 away from the negative terminal, the end of the second time relay *T1 away from the second time relay switch T1, and the end of the first self-locking relay *M0 away from the second time relay switch T1.

[0061] In this embodiment, when the first row control switch SB4 is opened, the first self-locking relay *M0 is activated, causing the first self-locking relay switch M0 to close, which in turn activates the first time relay *T0. The first time relay *T0 performs timing, and after the timing ends, it activates the first time relay switch T0, which in turn activates the second time relay *T1. This, in turn, activates the third PLC built-in switch Y3 in the motor mode selection circuit 40 via the control signal third PLC output point *Y3, enabling the motor to rotate forward via the third intermediate relay *KM3 in its circuit. The slash on the fourth time relay switch T3 indicates the on state, while the absence of a slash indicates the corresponding control state. The first row control switch SB4 controls six motors in one row, while other rows of motors are controlled by other switches. Therefore, the user can activate different row control switches as needed, enabling multi-gear break-in functionality and allowing selection of different modes depending on the situation. The forward and reverse rotation times for each mode can be set by the time relays, and the time relays for each waiting time can also be set, further meeting user needs and allowing for different modes and different times of gear break-in.

[0062] In one embodiment, reference is made to... Figure 7 As shown, the reverse break-in circuit includes the third PLC built-in switch Y3, the fourth PLC built-in switch Y4, the third switch SB2, the third time relay switch T2, the fourth time relay switch T3, the second self-locking relay M1, the second self-locking relay switch M1, the third time relay T2, and the fourth time relay T3;

[0063] The negative terminal of the first power supply 11 is connected to one end of the third PLC built-in switch Y3, one end of the second self-locking relay switch M1, and one end of the third time relay switch T2. The end of the third PLC built-in switch Y3 furthest from the negative terminal of the first power supply 11 is connected to the end of the second self-locking relay switch M1 furthest from the negative terminal of the first power supply 11 and one end of the fourth time relay switch T3. The end of the fourth time relay switch T3 furthest from the third PLC built-in switch Y3 is connected to one end of the third switch SB2. The end of the third switch SB2 furthest from the fourth time relay switch T3 is connected to one end of the second self-locking relay M1. The end of the second self-locking relay switch M1 away from the negative terminal of the first power supply 11 is also connected to one end of the third time relay *T2. The end of the third time relay switch T2 away from the negative terminal of the first power supply 11 is connected to one end of the fourth time relay *T3 and one end of the fourth PLC output point *Y4. The positive terminal of the first power supply 11 is connected to the end of the fourth PLC output point *Y4 away from the third time relay switch T2, the end of the third time relay *T2 away from the second self-locking relay switch M1, the end of the fourth time relay *T3 away from the third time relay switch T2, and the end of the second self-locking relay *M1 away from the third switch SB2.

[0064] In this embodiment, when the second time relay *T1 reaches its timing time, the third PLC output point *Y3 sends a falling signal to the third PLC built-in switch Y3, which activates the second self-locking relay *M1. This causes the second self-locking relay switch M1 to enter the 3-second timing period of the third time relay *T2. Simultaneously, when the second time relay *T1 finishes timing, it deactivates, causing the second time relay switch T1 in the forward running-in circuit to open. Consequently, the first self-locking relay *M0 deactivates, causing its switch to open, ending the forward rotation of the entire row of motors and initiating reverse rotation. The third time relay *T2 then starts timing and, upon completion, provides a rising edge voltage to activate the third time relay switch T2. This triggers the fourth time relay *T3 to start timing, and the control signal at the fourth PLC output point *Y4 activates the fourth PLC built-in switch Y4 in the motor mode selection circuit 40. This, in turn, activates the fourth intermediate relay *KM4 in the circuit, enabling the motor to rotate forward. This completes the control of the forward and reverse rotation of the entire row of motors. In the diagram, K30 represents the time relay's set time of 3 seconds. Another point is that the third switch SB2 in the reverse break-in circuit actually refers to the double control switch of SB2. When the switch control circuit selects the 014 mode of SB2, the third switch SB2 of the reverse break-in circuit will be disconnected because 014 will not be able to reverse. This prevents the 014 mode from entering the reverse control circuit, thus realizing the reverse function of 014. 011 and 013 will keep the third switch SB2 of the reverse break-in circuit in the normally closed state, realizing the multi-functionality of the gear break-in circuit.

[0065] Furthermore, refer to, for example Figure 6 As shown, a flowchart illustrating the first embodiment of the gear break-in control method of the present invention is presented based on an embodiment of the above-described motor break-in control circuit. The steps of the gear break-in control method include:

[0066] Step S10: Obtain the time information of the second time relay, and determine the working state of the first self-locking relay based on the time information;

[0067] In this embodiment, the internal gear break-in controller controls the timing information of the second time relay based on the acquired timing information, thereby achieving different states of the second time relay's timing information. The timing information refers to the internal timing of forward rotation within the second time relay, and the operating state refers to whether the first self-locking relay is in a conducting or self-locking state. The step of determining the operating state of the first self-locking relay based on the timing information includes:

[0068] Step A21: Obtain a preset threshold time value and detect whether the threshold time value matches the time information;

[0069] In this embodiment, the controller acquires a preset threshold time value and checks whether the threshold time value matches the time information. That is, the second time relay internally implements a self-detection function to check whether the current working time is the same as the preset threshold time value. By detecting the time information of the second time relay, the accuracy of the motor rotation time can be ensured.

[0070] Step A22: If the threshold time value matches the time information, the working state is that the first self-locking relay enters the self-locking state;

[0071] Step A23: If the threshold time value does not match the time information, the working state is that the first self-locking relay enters the non-self-locking state.

[0072] When the threshold time value matches the time information, the first self-locking relay enters a self-locking state. This means that when the forward rotation time reaches the threshold time value, the circuit stops supplying power for forward rotation and activates other circuits (the reverse control circuit). The self-locking state refers to the relay not operating, resulting in its own control logic being unresponsive. When the threshold time value does not match the time information, the first self-locking relay enters a non-self-locking state. This means that when the forward rotation time does not reach the threshold time value, the circuit will not stop supplying power for forward rotation, nor will it activate other circuits (the reverse control circuit). Simultaneously, it will update and detect the time information until it matches the threshold time value, at which point it enters the control phase of the reverse control circuit. Accurate detection of the time information ensures accurate control of both the forward and reverse rotation circuits.

[0073] Step S20: If the working state is a non-locking state, then continue to update the time information of the second time relay;

[0074] Step S30: If the working state is a self-locking state, then the reverse running-in circuit is turned on to reverse the motor.

[0075] In this embodiment, when the first self-locking relay is in a non-locking state, meaning it will not lock and allows the forward control circuit to operate normally, the time information of the second time relay is updated, and the operating state of the first self-locking relay continues to be monitored. When the first self-locking relay is in a locking state, meaning it will lock and disable the forward control circuit, the reverse break-in circuit will be activated to control the motor to reverse. This achieves accurate forward and reverse control of the motor.

[0076] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
