Abstract

The invention discloses equipment, a method, a device and a medium for testing pulsation torque of a motor, and the equipment comprises a measurement and control machine, a brake motor, a tested motor, a torque sensor and an acceleration sensor, the measurement and control machine is connected with the brake motor and the tested motor, and is used for enabling the brake motor and the tested motor to be in a constant rotating speed mode or a constant torque mode; the brake motor is connected with the motor to be tested, the torque sensor and the acceleration sensor are arranged on a connecting shaft of the brake motor and the motor to be tested to obtain angular acceleration and torque of the motor to be tested, and the measurement and control machine is connected with the torque sensor and the angular acceleration sensor. The additional torque is confirmed through the angular acceleration and the rotational inertia of the rotor of the tested motor, and the torque is compensated. Therefore, the additional torque is calculated through the rotational inertia and the angular acceleration, the torque is compensated according to the value of the additional torque, no additional equipment is used, the size and the weight of the testing equipment are reduced, and the precision of testing the pulsation torque of the motor is improved.

Description

technical field [0001] The present application relates to the technical field of automation, in particular to a device, method, device and medium for testing the pulsating torque of a motor. Background technique [0002] Due to the existence of many factors such as its magnetic pole structure, commutation and fluctuation of the driving current, the output torque of the motor will fluctuate, that is, the output torque of the motor for one revolution fluctuates around the average output torque value along the 2π angle. Call it pulsating torque. The pulsating torque is especially obvious when the motor is running at low speed, and excessive pulsating torque will seriously affect the output load characteristics of the motor. Therefore, it is necessary to test the pulsating torque in the process of R&D and manufacturing. The current method of testing the pulsating torque of the motor generally uses the braking device as the simulated load, and the torque sensor is connected to ...
