Electronic components need to be aging tested before they leave the factory. Aging is to make defects appear in a short period of time by allowing the semiconductor to overwork, avoiding failure in the early days of use. If not by aging, many semiconductor finished products will cause many problems in use due to the complexity of the device and manufacturing process. There are several main ways for stepper motor driver aging test:
    1. Driver performance test: mainly focused on driver efficiency, harmonic analysis, three-phase unbalance analysis, interference analysis and other test items;
    2, driver response test: mainly through the motor test bench, to apply different loads to the motor, observe the load changes when the motor driver can quickly adjust the working state of the motor according to the algorithm, evaluate the response performance of the drive.
    3, drive aging test: the main test drive aging resistance.
