Stepping motor stepper motor drives the aging test electronic components must be before they go out three ways to aging test. If there is no after aging test, a lot of semiconductor products with components and production process complexity in use will happen as a result of a number of problems. After aging test is for semiconductor overloaded operations and make the defects appeared in a short period of time, to prevent the use of early fault. Han debao electrical aging test first for stepper motor drives have this several ways: 1, the drive performance test: first converged on the drive efficiency, harmonic analysis, three-phase imbalance degree analysis and interference analysis test item. 2, the device response test: the first is a motor test bench, applying different load to the alternator, observe motor can drive the load change according to the algorithm quickly regulate the job status of motor, assessing response performance of the drive. 3, drive aging test: the primary test drive anti-aging ability.
