Abstract

The invention provides a cycle testing device and a testing method for a motor positive and negative rotation power module. The testing device comprises a testing power source input module, a voltage reducing, rectification and voltage stabilization module, a peripheral interface controller (PIC), and a signal switching control module, wherein the voltage of the power source input module provides working voltage for the PIC and the signal switching control module after the voltage reducing, rectification and voltage stabilization module, the PIC is connected with the signal switching control module which is connected with the motor positive and negative rotation power module to be tested, and the PIC is utilized to control the regular switch of motor positive and negative input signals. According to the cycle testing device and the testing method for the motor positive and negative rotation power module, the testing process is automatic without manual operation to switch testing input signals; the cycle testing mode can be programmed, and the working mode is set by key pressing, the testing requirements of different motor loads are more adapted; and a liquid crystal display (LCD) can be used to display the working mode so that accurate and convenient setting of working mode and modularization of testing mode are facilitated.

Description

technical field [0001] The invention relates to a test device and a test method for a motor forward and reverse power module, in particular to a programmable motor forward and reverse power module cycle test device and a test and a test method. Background technique [0002] In the test and inspection of the existing motor forward and reverse power module products, manual switching is often used to input the forward and reverse control voltage and manually control the forward and reverse execution time and switching frequency, resulting in a waste of manpower and a waste of execution time. It is also difficult to achieve precise and consistent control, so it is necessary to introduce a test method that is simple and easy to control and accurately tests the forward and reverse power modules of the motor. Contents of the invention [0003] Aiming at the problems of the prior art, the present invention proposes a motor forward and reverse power module cycle test device and tes...
