Problems solved by technology

In this test method, a dynamic sealing device is added to the transmission connection part of the box. The resistance torque of the dynamic sealing device and the additional torque of the tooling connection are relatively large, which may approach or exceed the test load. The test error for small-load motors is relatively large, so It cannot truly reflect the characteristics of the motor; the second is to carry out the load test through the load-hanging method of the motor output shaft and the torque test plate. After one load in the test chamber, only one load point performance test can be carried out, and continuous testing is not possible. The test time of this method is Long, uncertainties in the test process will affect the test results

Abstract

The invention provides a motor load working characteristic testing system and method. The testing system comprises a force measuring device, a control force measuring device, a load device and a control device, wherein the force measuring device and the control force measuring device are respectively arranged on two sides of a measured motor, and are used for testing torque forces of upper and lower ends of the measured motor, the load device is connected with the control force measuring device and is used for providing load for the measured motor, and the control device is electrically connected with the measured motor and the load device and is used for controlling the start and stop of the measured motor and the output axial force of the load device. According to the testing system, theeffect of changing the load of the measured motor can be realized by changing the output axial force of the load device, the motor load characteristic test can be carried out under special environmental conditions (high and low temperature, vacuum and the like), the load of the tested motor can be continuously changed by continuously adjusting and controlling the output axial force of the load device, different load performance tests of the tested motor can be completed, and the continuous test of the load characteristics of the tested motor can be realized.

Description

technical field [0001] The invention belongs to the technical field of motor laboratory testing, and in particular relates to a testing system and method for the load working characteristics of a motor. Background technique [0002] With the wide application of micro motors and the improvement of the refined application of motors in different environmental conditions by system equipment, it is particularly important to provide different environmental conditions of micro motors, especially the load characteristics at different temperatures or vacuum conditions. Due to factors such as motor structure and materials, there may be a large deviation between the theoretical calculation of the high and low temperature characteristics of the micromotor and the actual performance. Only theoretical calculations cannot meet the actual use needs. Therefore, it is necessary to test the micromotor in different environments such as high temperature and low temperature. Performance measureme...
