Device and method for testing motion performance of small and medium-sized AC permanent magnet synchronous motors

Abstract

The invention relates to a device and method for testing the movement performance of a small and medium-sized alternating current permanent magnet synchronous motor. The device comprises a bread slab platform. A dynamic torductor is arranged on the platform surface of the bread slab platform. The input end of the dynamic torductor is connected with the output end of the alternating current permanent magnet synchronous motor through an adaptor shaft. The output end of the dynamic torductor is connected to a magnetic powder brake through another adaptor shaft. An output shaft of the alternating current permanent magnet synchronous motor is sleeved with a photoelectric encoder. The alternating current permanent magnet synchronous motor is driven by a control drive electrical system. The output ends of the control drive electrical system, the photoelectric encoder and the dynamic torductor are electrically connected with the input end of a motor movement control performance detection system. The output end of the motor movement control performance detection system is electrically connected with the input end of the alternating current permanent magnet synchronous motor. The device for testing the movement performance of the small and medium-sized alternating current permanent magnet synchronous motor is light, handy, portable and convenient to use, and technical staff can conveniently research new control strategies for optimizing the alternating current permanent magnet synchronous motor under different working conditions.

AI Technical Summary

Problems solved by technology

By testing the control strategy of small and medium-sized AC permanent magnet synchronous motors in finished equipment, it is impossible to simulate various working conditions required for testing the control strategy, and it is also impossible to monitor data such as control quantities, output quantities, and parameter estimates during the operation of the motor. It will be very difficult to improve the new control strategy, and the unknown defects of the control strategy may cause damage to the equipment, and the cost of testing is also high

[0004] Therefore, the control strategy test is generally done on the motor experiment platform, but most of the existing motor test platforms are cast iron T-slot platforms, which are large in size, heavy in weight, and difficult to move. Motor test not applicable
