[0022] See also Figure 1 , Figure 1 This is a structural block diagram of a device for detecting a motor speed regulator provided by an embodiment of the present invention. Figure 1 As shown, the device 100 for detecting a motor speed regulator includes an eddy current 11, a motor 12, and an automatic throttle control module 13. The device 100 for detecting a motor speed regulator is used to detect the motor speed regulator 200. The automatic throttle control module 13 is connected to the motor speed regulator 200, which is further connected to the motor 12, and the motor 12 is connected to the eddy current 11.

[0023] Specifically, when the device 100 for detecting the motor speed regulator starts to detect the motor speed regulator 200, the automatic throttle control module 13 obtains the operating threshold of the motor speed regulator 200 and sends a control signal to the motor speed regulator 200 based on the operating threshold. After receiving the control signal sent by the automatic throttle control module 13, the motor speed regulator 200 adjusts the speed of the motor 12 according to the control signal to drive the eddy current 11 to operate through the motor 12. When the eddy current 11 is running, the motor speed regulator 200 also receives the operating signal fed back by the eddy current 11 to detect the performance of the motor speed regulator 200 according to the operating signal.

[0024] Among them, the device 100 for detecting the motor speed regulator needs to detect the performance of the motor speed regulator 200 including current tolerance and impact tolerance; the control signal sent by the automatic throttle control module 13 includes a first control signal and a second control signal. When it is necessary to detect the current tolerance of the motor speed regulator 200, the automatic throttle control module 13 will send the first control signal to the motor speed regulator 200, and when it is necessary to detect the impact tolerance of the motor speed regulator 200, the automatic throttle control module 13 will send the second control signal to the motor speed regulator 200. Before the automatic throttle control module 13 sends the first control signal and the second control signal, the automatic throttle control module 13 also obtains the operating threshold of the motor speed regulator 200, wherein the operating threshold includes a current threshold and an impact force threshold, and sets the first control signal according to the current threshold, and sets the second control signal according to the impact force threshold, so that the eddy current 11 feeds back an operating signal that is higher than the current threshold or the impact force threshold to the motor speed regulator 200, thereby detecting the current tolerance or impact force tolerance of the motor speed regulator 200. It should be noted that the first control signal and the second control signal are obtained by adding a preset threshold to the current threshold and the impact force threshold, and the preset threshold is used to make the operating signal fed back by the eddy current higher than the operating threshold of the motor speed regulator.

[0025] When the motor speed regulator 200 receives the first control signal, the motor speed regulator 200 will control the speed of the motor 12 to reach the first speed within the first preset time based on the first control signal. When the motor 12 reaches the first speed, the motor 12 will drive the eddy current 11 to run. At this time, the running speed of the eddy current 11 is also the first speed. When the eddy current 11 runs at the first speed, the eddy current 11 will generate a momentary high current, and the momentary high current will be input into the motor speed regulator 200 through the motor 12 to detect the current tolerance of the motor speed regulator 200. Among them, the first speed is the maximum speed of the motor 12 when it is running, and the first preset time is set to enable the motor 12 to quickly reach the first speed, so that the eddy current 11 can quickly reach the maximum speed from a static state, thereby generating a momentary high current. Optionally, the first preset time is 0.5s.

[0026] When the motor 12 runs at the first speed for a second preset time, the automatic throttle control module 13 will also send a second control signal to the motor speed regulator 200. After the motor speed regulator 200 receives the second control signal, it controls the motor 12 to reach a second speed within a third preset time based on the second control signal. When the motor 12 runs at the second speed, it drives the eddy current 11 to run at the second speed. At this time, the eddy current 11 will generate an instantaneous impact force, and the instantaneous impact force is input to the motor speed regulator 200 through the motor 12 to detect the impact force tolerance of the motor speed regulator 200. The second speed refers to the speed of the motor 12 when it stops running; the second preset time is greater than the first preset time and the third preset time. The first preset time and the third preset time can be the same time or different times. It should be noted that the second preset time is used to allow the motor 12 to reach a stable state before adjusting its speed. This prevents damage to the motor 12 due to sudden changes in its speed during acceleration or deceleration. The third preset time is used to quickly bring the motor 12 from its maximum speed to a disabled state, thereby generating an instantaneous impact force. Optionally, the second preset time is 30 seconds, and the third preset time is 0.5 seconds.

[0027] In some embodiments, the control signal sent by the automatic throttle control module 13 can also be set according to the detection task. Specifically, when the device 100 for detecting the motor speed regulator starts running, the detection task of the device 100 for detecting the motor speed regulator is determined based on the state of the motor 12. For example, when the speed of the motor 12 reaches a first speed, it is considered that the detection task of the device 100 for detecting the motor speed regulator is to detect the impact tolerance of the motor speed regulator 200; when the speed of the motor 12 reaches a second speed, it is considered that the detection task of the device 100 for detecting the motor speed regulator is to detect the current tolerance of the motor speed regulator 200. After determining the current detection task based on the speed of the motor 12, the automatic throttle control module 13 will send a corresponding control signal to the motor speed regulator 200 based on the detection task, so that the motor speed regulator 200 controls the speed of the motor 12 according to the control signal.

[0028] In some embodiments, as Figure 1 As shown, the device 100 for detecting the motor speed regulator further includes a reduction gearbox 14, wherein the reduction gearbox 14 is connected to the eddy current 11 and the motor 12, respectively. The reduction gearbox 14 is used to obtain the output speed of the motor 12, and reduce the output speed of the motor when the output speed of the motor 12 exceeds a first preset threshold; and increase the output speed of the motor 12 when the output speed of the motor 12 exceeds a second preset threshold, so that the output speed of the motor 12 is within the tolerance range of the eddy current 11, thereby protecting the eddy current 11. Specifically, when the motor speed regulator 200 controls the speed of the motor 12 according to the control signal, the motor 12 will cause the eddy current 11 to run at the same speed based on the speed. At this time, if the speed of the motor 12 exceeds the speed tolerance range of the eddy current 11, the eddy current 11 will be damaged. At this time, by providing a reduction gearbox 14 between the motor 12 and the eddy current generator 11, the speed output by the motor 12 is adjusted when the speed of the motor 12 is too high or too low, thereby ensuring that the eddy current generator 11 operates within a preset range. The first preset threshold value refers to the fastest speed at which the eddy current generator 11 can operate, and the second preset threshold value refers to the slowest speed at which the eddy current generator 11 can operate.

[0029] In some embodiments, as Figure 1 As shown, the device 100 for detecting a motor speed regulator further includes a coupling 15, which is used to connect the eddy current sensor 11 and the reduction gearbox 14, and to connect the reduction gearbox 14 and the motor 12. The coupling 15 is used to drive the reduction gearbox 14 and the eddy current sensor 11 to rotate together during the operation of the motor 12.

The automatic throttle control module is used to obtain the operating threshold of the motor speed regulator and send a control signal to the motor speed regulator based on the operating threshold; the motor speed regulator is used to receive the control signal sent by the automatic throttle control module and adjust the speed of the motor according to the control signal to drive the eddy current to operate through the motor; when the eddy current is operating, the motor speed regulator is also used to receive the operating signal fed back by the eddy current to detect the performance of the motor speed regulator according to the operating signal. Based on this, the motor speed regulator can receive different feedback signals according to the different motor speeds, thereby saving detection time and steps while detecting the performance of the motor speed regulator.
