Abstract

The invention relates to a servo motor test bench and a test method. The invention aims to provide a servo motor test bench which has high detection precision and is not related to the rotating speed of a motor, and a test method. The servo motor test bench comprises a test bench and a load motor mounted on the test bench; a rotor of the load motor is connected with a rotor of a to-be-tested servo motor; a stator of the to-be-tested servo motor is fixedly connected with the test bench; a stator of the load motor is movably connected with the test bench; and the test bench is also provided with a pressure sensor for detecting the rotation moment of the stator of the load motor. The servo motor test bench has the advantages that the torque change process of the to-be-tested servo motor can be detected when the to-be-tested servo motor is subjected to load change, the detection precision is not affected by the given velocity value, the requirement for the torque detection of the large-range speed value of the servo motor can be met, and the detection results are visual and brief.

Description

technical field [0001] The invention relates to the field of servo motor manufacturing, more specifically, the invention relates to a servo motor test bench and a test method for electrical testing of the servo motor. Background technique [0002] Generally, when testing the electrical performance of the motor, the stators of the motor under test and the load motor are fixedly connected to the test bench, and the rotor of the motor under test and the rotor of the load motor are softly connected through a coupling. In the case of electrification separately, various performance parameters of the motor under test are calculated by measuring various electrical parameters. The disadvantage of this test method is that, because the performance parameters of the motor under test are obtained indirectly, the error is relatively large; secondly, generally only the average value can be obtained, and it is difficult to obtain the instantaneous value. For example, when testing the torqu...
