Abstract

The invention provides a motor test system and method. The motor test system comprises a clamp for clamping a to-be-tested motor stator, a dynamometer for testing the power of the to-be-tested motor,a connection shaft connected with an extending shaft of the dynamometer and a bearing, wherein the bearing comprises a main shaft connected with the connection shaft and a shaft sleeve sleeving the main shaft; the shaft sleeve and the clamp are fixedly arranged; and the main shaft is suspended in the shaft sleeve. According to the motor test system and method provided in the invention, through suspending the main shaft connected with the rotor of the to-be-tested motor in the shaft sleeve, direct contact with the inner wall of the shaft sleeve in the case of rotating of the main shaft is avoided, the mechanical friction loss of the motor test system is reduced, and the stability and the consistency in the case of motor test can be improved.

Description

technical field [0001] The invention belongs to the technical field of motor testing, and in particular relates to a motor testing system and method. Background technique [0002] During the development process of refrigerator compressors, the efficiency of the motor largely determines the energy-saving effect of the compressor; in addition, the pursuit of cost-effective compressor products requires the motor to reasonably meet the power demand of the compressor pump body load. In both cases, technicians need to evaluate the output power, speed, current and efficiency through the motor performance test bench to judge the pros and cons of the design scheme. [0003] At present, there are many motor performance testing equipment, such as figure 1 As shown, the motor performance testing equipment includes a regulated variable frequency power supply 1', a test bench 2', a dynamometer 3', a fixture for the motor under test 4', a dynamometer controller 5', a power analyzer 6', an...
