Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention is further described as follows:

[0016] Such as figure 1 with figure 2 As shown, the motor plus periodic step load endurance test method, the motor 1 is connected with the hysteresis brake 3 through the coupling 2, the real-time torque of the motor 1 is monitored through the torque sensor 5, and the real-time torque is transmitted to the control system 4, After the control system 4 compares the real-time torque with the set torque, it controls the hysteresis brake 3 to adjust the braking voltage to adjust the loading of the motor 1; the real-time torque is only monitored at the middle position of the motor swing.

[0017] Traditionally, the loading torque is detected near the two limit positions of the motor swing. At this time, the monitored torque is either small or large compared with the actual value, so that the torque actually loaded on the motor 1 will have very large fluctuations. The pre...

Abstract

The invention discloses a motor periodic ladder load endurance test method, which belongs to the field of motor control. A motor is connected with a magnetic remanence brake through a coupling; through a moment sensor, the real-time moment of the motor is monitored and is transmitted to a control system; after the control system compares the real-time moment with a set moment, the magnetic remanence brake is controlled to regulate brake voltage to regulate the load of the motor; and the real-time moment is monitored only on a motor swinging middle position. By use of the method, a way of detecting a loading moment near two traditional motor swinging limiting positions is abandoned, the real-time moment is detected only on the motor swinging middle position, a deviation between a detectionvalue and a practical value is greatly reduced, so that the fluctuation of the load loaded to the motor through closed-loop control is small, and a load fluctuation quantity is controlled within + / -0.1N.m.

Description

technical field [0001] The invention belongs to the field of motor control, in particular to an endurance test method for a motor plus a periodic step load. Background technique [0002] The wiper motor needs to be tested for durability before it is put into use to ensure the control precision and accuracy of the wiper motor. At present, the torque loading system is usually used to test the wiper motor. The torque loading system includes a torque sensor, a hysteresis brake and a control system. The real-time torque of the motor is detected by the torque sensor, and the detected real-time torque is fed back to the control system. The hysteresis brake voltage is adjusted by the control system to adjust the actual load of the motor. However, the torque actually loaded to the motor will have very large fluctuations, and the fluctuation of the loading torque exceeds ±0.4N.m, which does not meet the standard requirements. Contents of the invention [0003] The purpose of the p...
