Description
technical field [0001] The invention relates to a motor test system, in particular to a motor temperature control test system based on a field effect tube drive circuit. Background technique [0002] With the development of the national economy and science and technology, motors play an increasingly important role in all walks of life. At the same time, with the development of various industries, higher and higher requirements are put forward for motor products, so motor products need to pass some test items to verify whether their characteristics meet the application requirements. Therefore, the motor testing technology is of great significance to the performance verification of the motor. [0003] However, the driving speed of the traditional motor test system is slow, and the efficiency is low when detecting the temperature of the motor, so that the motor test system cannot control the working temperature of the motor in time. Contents of the invention [0004] The pu...
