[0035] See also Figure 1 The present invention provides a method for controlling automatic speed change of an intelligent motor, comprising the following steps:

[0036] S10. The intelligent sensor, intelligent protector, and intelligent tester provided on the information acquisition module obtain information such as the speed, voltage, temperature, static electricity, noise, and functional abnormality of the circuit, and transmit the information to the control center;

[0037] S20, the control center compares the actual motor operating parameter information with the motor target speed and safe operating parameters stored in the memory: if the information is consistent, the speed is maintained and the operation continues; if the information is inconsistent, the alarm is transmitted to the alarm and the functional protection module is notified to adjust the parameters;

[0038] S30. The functional protection module adjusts the actual parameter information of the motor such as the circuit, structure, differential, overload, high temperature, high voltage, static electricity, and abnormal functional protection information to realize differential protection and overload protection of the motor to ensure the normal operation and life of the motor, and transmits the information to the data optimization module. If the motor is accelerated but the high temperature control is ignored, the motor will overheat and cause a fire accident.

[0039] To further explain, the so-called high temperature of the motor refers to the temperature that is too high when the motor is running. If it exceeds the normal temperature, it will cause a fire. It is generally caused by abnormal power supply, abnormal load, abnormal motor, and poor ventilation and heat dissipation.

[0040] It is further explained that the power supply abnormality includes the power supply voltage being too high or too low, voltage asymmetry, three-phase power supply imbalance, etc., which may cause the motor to overheat. When the power supply voltage is too high, the motor's back electromotive force, magnetic flux and magnetic flux density will increase accordingly. Since the iron loss is proportional to the square of the magnetic flux density, the iron loss increases, causing the iron core to overheat, and the increase in magnetic flux causes the excitation current component to increase sharply, causing the stator winding copper loss to increase and the winding to overheat. Therefore, when the power supply voltage exceeds the rated voltage of the motor, the motor will overheat; when the power supply voltage is too low, if the electromagnetic torque of the motor remains unchanged, the magnetic flux will decrease, the rotor current will increase accordingly, and the load power component in the stator current will increase accordingly, causing the copper loss of the winding to increase, resulting in overheating of the stator and rotor windings; when the power supply voltage is asymmetric, one phase of the power line is disconnected, one phase of the fuse is blown, or the angle head of the knife starting device is burned, causing one phase to be blocked, the three-phase motor will run in single phase, causing the running two-phase winding to pass large current and overheat, and even burn out; when the three-phase power supply is unbalanced, the three-phase current of the motor will be unbalanced, causing the winding to overheat.

[0041] To further clarify, abnormal loads include motor overload, abnormal operation of the driven mechanical load, or motor overheating caused by a fault in the driven machinery. When the motor is overloaded or the equipment is incompatible, the motor load power exceeds the rated power of the motor, resulting in long-term overload and overheating. When the mechanical load driven by the motor is operating abnormally, the load fluctuates, causing the motor to overload and heat. When the driven machinery malfunctions, the motor becomes stiff or stuck, all of which can cause the motor to overload and overheat its windings.

[0042] Further explanation: the motor abnormalities include motor winding open circuit and short circuit, wrong or reverse motor connection, motor mechanical failure, etc., which lead to overheating. When one phase of the motor winding is open circuit, or one branch in the parallel branch is open circuit, it will cause three-phase current imbalance, causing the motor to overheat; when a short circuit occurs in the motor winding, the short circuit current is much larger than the normal operating current, which increases the copper loss of the winding, causing the winding to overheat, or even burn out; when the delta-connected motor is mistakenly connected to a star, the motor still runs at full load, and the current flowing through the stator winding exceeds the rated current, which may even cause the motor to stop automatically. If the stop time is slightly longer and the power is not cut off, The winding will not only overheat seriously, but also burn out; when a star-connected motor is mistakenly connected into a triangle, or a motor with several coil groups in series in one branch is mistakenly connected into two branches in parallel, the winding and the iron core will overheat, and in severe cases, the winding will burn out; when a coil, coil group or one-phase winding is connected reversely, it will cause a serious imbalance in the three-phase current, causing the winding to overheat; when the motor shaft is bent, poorly assembled, or the bearing has problems and other mechanical faults, the motor current will increase, copper loss and mechanical friction loss will increase, causing the motor to overheat.

[0043] Further explanation: the poor ventilation and heat dissipation leading to motor overheating include: the ambient temperature is too high, causing the air inlet temperature to be high; the air inlet is blocked by debris, making the air inlet poor and resulting in a small air intake volume; there is too much dust inside the motor, affecting heat dissipation; the fan is damaged or installed upside down, resulting in no wind or small air volume; there is no wind hood or no wind shield installed in the motor end cover, resulting in the motor having no certain air path.

[0044] S40. The data optimization module performs data optimization processing based on the functional protection information and the actual motor operation parameter information, eliminates parameters that are useless for acceleration, obtains parameter information that is useful for acceleration, and transmits the information to the acceleration parameter module. This ensures that the motor can be accelerated, braked, and reversed at high speed without affecting its lifespan, thereby reducing energy consumption during the conversion process and maximizing energy efficiency.

[0045] S50, the acceleration parameter module selects the motor acceleration process parameters and acceleration program instructions according to the motor acceleration parameter information, and transmits them to the drive acceleration module;

[0046] S60, the driving acceleration module controls the motor's acceleration according to the acceleration process parameters and the acceleration program instructions, and transmits them to the information acquisition module, and executes the above steps S10 to S60 until the motor reaches the target speed.

[0047] See also Figure 2 The present invention provides a control method for automatic speed change of an intelligent motor, which also includes a control system for automatic speed change of an intelligent motor, including: an information acquisition module, a function protection module, a data optimization module, an acceleration parameter module, a drive acceleration module, a wireless communication module, an alarm, a memory, a control center, and a smart phone; the information acquisition module, the function protection module, the data optimization module, the acceleration parameter module, the drive acceleration module, the wireless communication module, the alarm, and the memory are respectively connected to the control center; the smart phone is automatically networked with the wireless communication module through the Internet of Things or the Internet within the scope of the Internet of Things or the Internet.

[0048] When the actual operating parameter information of the motor is inconsistent with the stored motor target speed and safe operating parameters, the alarm automatically sounds an alarm and transmits the information to the functional protection module to adjust the parameters.

[0049] The memory is responsible for storing information of the information acquisition module, function protection module, data optimization module, acceleration parameter module, and drive acceleration module, as well as storing the safe operation parameters and target speed of the motor.

[0050] The wireless communication module is provided with an Internet of Things module, which can automatically form a network within the scope of the Internet of Things or the Internet, and connect to the wireless network of the smartphone, and is responsible for sending and receiving wireless network signals.

[0051] The control center is responsible for information transmission among the information acquisition module, function protection module, data optimization module, acceleration parameter module, drive acceleration module, wireless communication module, alarm, and memory. It is the hub of the system and compares the actual parameter information of the motor operation with the motor target speed and safe operation parameters stored in the memory: if the information is consistent, the speed is maintained and the operation continues; if the information is inconsistent, the information is transmitted to the alarm and the function protection module is notified to adjust the parameters.

[0052] The data optimization module performs optimization processing based on data that is beneficial to functional protection and motor acceleration, eliminates useless parameter data, retains useful parameter data, and transmits the data to the acceleration parameter module.

[0053] The information acquisition module is equipped with intelligent sensors, intelligent protectors, and intelligent testers, which are responsible for obtaining actual parameter information such as the speed, voltage, temperature, static electricity, noise, and functional abnormalities of the circuit, and transmitting it to the control center.

[0054] It is further explained that the intelligent sensor has sensing functions for voltage, current, power, temperature, static electricity, noise, etc., and is responsible for obtaining various performance parameters of the circuit, such as current, voltage, power, efficiency, power factor, speed, temperature, noise, etc.

[0055] It is further explained that the intelligent protector is responsible for obtaining abnormal information such as motor overload, phase loss, stall, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, bearing wear, stator and rotor eccentricity, axial movement and radial runout, which can ensure the service life and normal operation of the motor.

[0056] It is further explained that the intelligent tester has the functions of testing the winding, vibration, balance, laser calibration, etc. of the motor. It is responsible for obtaining the winding parameters such as the resistance / inter-turn voltage / insulation resistance of the motor, whether the motor vibrates during operation, dynamic balance correction, whether the motor axis and coupling are accurately relative, etc. It can determine whether there is any abnormality in the motor, improve the smoothness and stability of the motor operation, and ensure the matching accuracy of the motor and the transmission system.

[0057] The functional protection module is responsible for adjusting the actual parameter information of the motor such as circuit, structure, differential, overload, high temperature, high voltage, static electricity, and abnormal functional protection information to realize differential protection and overload protection of the motor to ensure the normal operation and life of the motor, and pass it to the data optimization module.

[0058] It is further explained that the differential protection includes differential quick-break protection and compound ratio differential protection with or without second harmonic braking. It can be used in situations with three-side differential current input (three-turn transformer) at most. It has a complete and powerful acquisition function for the analog and switch quantities of voltage and current of primary equipment. It is equipped with standard RS485 and industrial CAN communication ports, and through reasonable configuration, it can realize protection and measurement and control functions such as three-turn main transformer differential protection, two-turn main transformer differential protection, two-turn distribution transformer differential protection, generator differential protection, motor differential protection and non-electrical quantity protection.

[0059] To further clarify, the overload protection mentioned above refers to the fact that motor coils are typically wound with very fine copper wire, which has poor current resistance. When the motor is heavily loaded or stuck, the current flowing through the coils increases rapidly, causing the motor temperature to rise sharply, and the copper wire windings are very likely to burn out. If a polymer PTC thermistor can be connected in series with the motor coil, it will provide timely protection when the motor is overloaded and prevent the motor from burning out. Therefore, thermistors are installed near the coils to better sense the temperature, making protection more rapid and effective. This includes using the KT250 thermistor with a higher voltage rating as primary protection, and using the KT60-B, KT30-B, KT16-B, and sheet-type motors with lower voltage ratings as secondary protection.

[0060] Further explanation: the functional protection information abnormalities include: when overload causes the winding current to increase, the winding and core temperature to rise, and in severe cases, a fire may be caused; when phase-out operation causes the winding current to increase, the motor may be burned and a fire may be caused; when contact is poor, the contact resistance may be too large and heat may be generated or an arc may be generated, and in severe cases, the combustibles in the motor may be ignited and a fire may be caused; when insulation damage occurs, phase-to-phase and turn-to-turn short circuits may be formed, thereby causing a fire; when mechanical friction causes bearing damage, it may cause stator and rotor friction or the motor shaft to be stuck, generating high temperature or winding short circuit and causing a fire; when the core consumption is too large, the eddy current loss may be too large, causing the core to heat up and the winding to overload, and in severe cases, a fire may be caused; when a winding pair is short-circuited, the grounding may be poor, which may cause the motor casing to be charged, which may cause personal electric shock accidents on the one hand, and cause the casing to heat up on the other hand, and in severe cases, ignite the surrounding combustibles and cause a fire.

[0061] The acceleration parameter module selects the process parameters and program acceleration instructions for motor acceleration according to the optimized motor data information, and transmits them to the drive acceleration module.

[0062] The driving acceleration module is provided with a small accelerator, which controls the acceleration of the motor according to the acceleration process parameters and the acceleration program instructions, and transmits them to the information acquisition module.

[0063] To further explain, the accelerator is a device that can change the motion state of an object to increase the object's running speed. It includes multiple components such as a power supply, an accelerator tube, a boost tube, a pulse generator, and an electronic controller. Its principle is: the power supply converts direct current into alternating current and inputs it into the accelerator tube, thereby converting electrical energy into magnetic field energy; the boost tube converts the magnetic field energy into kinetic energy and transmits it to the pulse generator; the pulser converts the kinetic energy into pulse energy and transmits it to the electronic controller; the electronic controller converts the pulse energy into electromagnetic field energy, thereby changing the motion state of the matter and making the matter move at high speed.

[0064] System working principle:

[0065] When the motor is running, the intelligent sensor, intelligent protector and intelligent tester set on the information acquisition module obtains the speed, voltage, temperature, static electricity, noise, functional abnormality and other information of the circuit, and transmits it to the control center; then the control center compares the actual parameter information of the motor operation with the motor target speed and safe operation parameters stored in the memory: if the information is consistent, the speed is maintained and the operation is continued; if the information is inconsistent, it is transmitted to the alarm and notified to the functional protection module to adjust the parameters; then the functional protection module adjusts according to the actual parameter information of the motor's circuit, structure, differential, overload, high temperature, high voltage, static electricity, functional protection information abnormality, etc., to realize differential protection and overload protection of the motor to ensure the normal operation and life of the motor, and transmits it to the data Optimization module; then the data optimization module performs data optimization processing based on the functional protection information and the actual parameter information of the motor operation, eliminates parameters that are useless for acceleration, obtains parameter information that is useful for acceleration, and passes it to the acceleration parameter module, so that the motor can be accelerated, braked and reversed at high speed without affecting its life under the premise of normal operation of the motor, so that it can reduce energy consumption during the conversion process, thereby maximizing energy utilization efficiency; then the acceleration parameter module filters out the process parameters and acceleration program instructions for motor acceleration according to the motor acceleration parameter information, and passes them to the drive acceleration module; then the drive acceleration module controls the acceleration of the motor according to the acceleration process parameters and acceleration program instructions, and passes it to the information acquisition module; until the motor accelerates to the target speed.

[0066] When the motor operator or manager is outdoors or on a business trip, he or she can use a smart phone to automatically establish a network within the Internet of Things or the Internet, and connect to the motor's wireless network through a wireless communication module, so as to control or monitor the operation of the motor, thereby achieving intelligent control and wireless network control of the motor. The motor can be accelerated, braked and reversed at high speed without affecting its life under the premise of ensuring normal operation of the motor, so that it can reduce energy consumption during the conversion process, thereby maximizing energy utilization efficiency.
