Abstract

The invention discloses a motor temperature control test system based on peak clipping pulse wave modulation control, comprising a single chip microcomputer (1), a power supply module (2), a motor rotating speed control module (3), a rotating speed signal processing module (5), a display (7), and a temperature storage module (10) which are all in connection with the single chip microcomputer (1), a motor (4) to be detected in connection with the motor rotating speed control module (3), a speed transmitter (6) and a temperature sensor (8) which are in connection with the motor (4) to be detected, and a bandwidth-limited circuit (9) in connection with the temperature sensor (8); the power supply module (2) is respectively in connection with the motor rotating speed control module (3) and the temperature storage module (10) ; a peak clipping pulse wave modulation circuit (11) is arranged between the single chip microcomputer (1) and the bandwidth-limited circuit (9). Through the peak clipping pulse wave modulation circuit, the motor temperature control test system can increase stability, and thereby accurately control motor temperatures.

Description

technical field [0001] The invention relates to a motor test system, in particular to a motor temperature control test system based on peak-shaving pulse modulation control. 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 traditional motor test system is not stable in detecting the motor temperature, which may easily cause the motor test system to fail to control the motor operating temperature in time. Contents of the invention [0004] The purpose of the present invention is...
