Abstract

The invention discloses a three-phase asynchronous motor efficiency characteristic test system and test method. The test system is characterized in that a power tester is arranged at an input end of a motor and used for testing the input power of the motor; a torque rotating speed tester is arranged on the output shaft of the motor and used for testing the output torque and the angular velocity of the motor; a magnetic powder clutch is arranged at tail end of the output shaft of the motor and used for loading of the motor. Test of a load rate and an efficiency characteristic of a motor can be carried out rapidly and accurately.

Description

technical field [0001] The invention relates to a test system and a test method, in particular to a motor characteristic test system and a test method. Background technique [0002] The motor system has a large number and a wide range of applications, and is a power-consuming machine that consumes a lot of electricity. According to statistics, the total power consumption of motors in my country accounts for about 60% of the total electricity consumption in society, and the total power consumption of motors in the industrial field accounts for about 75% of industrial electricity consumption. The energy efficiency level of motors in my country is low. Part of the reason is that the efficiency of the motor itself is low. The other part is that the matching of the motor system is unreasonable. In some occasions where the load changes greatly, the motor will often run away from the high-efficiency point, resulting in low efficiency. A lot of energy is wasted; therefore, it is of ...
