Description

Technical Field

[0001] The utility model relates to the field of dual-speed permanent magnet drive equipment, in particular to a dual-speed permanent magnet driver. Background Art

[0002] A dual-speed permanent magnet drive is generally regarded as a dual-speed motor. It has the ability to run at two different speeds, which is achieved by changing the number of electromagnetic poles of the motor. It can achieve dual-speed operation. It is based on permanent magnet motor technology and can operate at two different speeds through a specific design. The realization of the dual-speed function depends on changing the number of electromagnetic poles of the motor, specifically by adjusting the connection method of the motor stator winding, thereby changing the magnetic field distribution inside the motor, thereby affecting the speed. This type of drive is widely used in many fields such as shipbuilding and marine engineering, automotive industry and high-precision industrial machinery due to its high efficiency, energy saving and strong stability.

[0003] The existing dual-speed permanent magnet drive base is based on the "An Energy-Saving Dual-Speed ​​Motor" mentioned in the patent number "202321214196.5", which discloses an energy-saving dual-speed motor, including a shell, a support frame is fixedly installed at the bottom of the shell, a base frame is fixedly installed at the bottom of the support frame, a threaded groove is provided on one side surface of the base frame, a screw is movably connected inside the threaded groove, a fixing box is fixedly installed on the top of the shell, a back cover is movably connected to one side of the shell, a connecting rod is fixedly installed on one side of the back cover, and a bolt is provided on one side surface of the connecting rod; this energy-saving dual-speed motor, through the arrangement of a heat-dissipating plate and a fan, when the dual-speed motor is running, a large amount of heat will be generated in the shell. If the temperature is not reduced in time, the use efficiency of the dual-speed motor will be affected, and the dual-speed motor will also be damaged. This patent, through the arrangement of a heat fan plate and a fan, effectively discharges the heat in the shell, and also improves the heat dissipation effect. Such an arrangement prevents the motor from being short-circuited or damaged due to excessive heat. However, there are still some defects. For example, although the heat fan plate and the fan can effectively dissipate heat, the heat dissipation port of the heat fan plate is relatively large, which may cause insects such as cockroaches to enter the heat dissipation plate through the heat dissipation port to build nests after the dual-speed permanent magnet drive is placed in a warehouse when not in use. In addition, in order to avoid insects from entering through the heat dissipation port, the heat dissipation efficiency may be affected. Therefore, it is necessary to provide a new type of dual-speed permanent magnet drive, which will not affect the heat dissipation efficiency when the dual-speed permanent magnet drive is used normally, and can prevent insects from entering when the dual-speed permanent magnet drive is not in use, thereby improving the overall practicality.

By setting the injection hole 506 to be plugged into the external injection needle, accurate filling of the lubricant is achieved, avoiding the problem that the traditional liquid guide port is large and easy to mix with impurities, thereby ensuring the purity and lubricating effect of the lubricant.

[0049] See also Figure 1 , Figure 2 A mounting mechanism 2 is provided at the bottom of the housing 101, and the mounting mechanism 2 includes a connecting plate 201. A base 202 is provided at the bottom of the connecting plate 201. By providing the mounting mechanism 2, a stable foundation is provided for the installation of the driver, so that the driver can be firmly fixed at a predetermined position, thereby improving the stability and safety of the device.

[0050] See also Figure 1 , Figure 2Two adjustment holes 203 are provided at the top of the base 202, and tightening bolts 204 are slidably connected in the adjustment holes 203. By providing two adjustment holes 203 at the top of the base 202 and slidably connecting the tightening bolts 204, the installation of the driver is more flexible and convenient, which can adapt to the needs of different installation environments and improve the applicability and installation efficiency of the equipment.

[0051] See also Figure 1 , Figure 2 A heat dissipation fin 102 is provided on the outer side of the shell 101, an output terminal 103 is provided on the other side of the shell 101, and a connector 104 is installed on the output terminal 103.

[0052] The implementation principle of the utility model is as follows: first, the driver 1 is fixed in an appropriate position using the mounting mechanism 2. This generally involves placing the base 202 in a predetermined position, firmly fixing the connecting plate 201 and the driver housing 101 on the base 202 through the adjustment holes 203 and the tightening bolts 204, and ensuring that the circuit line 403 is properly connected to the driver 1, so as to provide power and control signals to the electric push rod 402 and other electronic components;

[0053] When the driver 1 needs to be started, the control system first sends a signal to start the electric push rod 402. After the electric push rod 402 is started, the connecting rod 406 pulls the rotating seat 405, thereby driving the sealing cover plate 407 to open, exposing the exhaust port of the heat dissipation fan shell 301, so as to ensure that the driver can effectively dissipate heat during operation. During the operation of the driver 1, the heat dissipation mechanism 3 helps to dissipate the heat generated inside through the heat dissipation fan shell 301 and the heat dissipation fins 102. The design of the heat dissipation fan shell 301 ensures that even when running at high speed, it can effectively prevent external debris from entering the driver.

[0054] When the driver 1 is turned off or no longer needs to be operated, the control system will cut off the power supply of the electric push rod 402. After the power is cut off, the electric push rod 402 no longer applies traction to the rotating seat 405, so that the sealing cover plate 407 automatically closes the exhaust port of the heat dissipation fan housing 301 under the action of a reset mechanism such as gravity or a spring. This automatic sealing function effectively prevents insects or other small animals from entering the heat dissipation mechanism 3 when the driver is not in use, thereby keeping the interior of the driver clean and safe.

[0055] In addition, the driver is regularly maintained and inspected to ensure its normal operation. If lubrication is found to be needed, it can be performed through the lubrication mechanism 5. Specifically, the closing cover 503 is opened, and lubricating liquid is injected into the liquid guide seat 501 through the injection hole 506, and then the closing cover 503 is closed to ensure that the sealing strip 504 fits tightly to prevent leakage of lubricating liquid or entry of contaminants.

[0056] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
