How to judge whether the stepping motor is aging

Stepper motor is an open-loop control motor that converts electric pulse signal into angular displacement or linear displacement. It is the main executive component of modern digital program control system, and is widely used. In the case of non overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and is not affected by the load change It works step by step from a fixed angle and controls the angular displacement by controlling the number of pulses to achieve the purpose of precise positioning. At the same time, the price of the driver controls the motor speed and speed by controlling the pulse frequency Acceleration, to achieve the purpose of speed regulation.

1. Step motor driver response test

Response test is mainly through the motor test-bed, the driver manufacturer to apply different loads on the motor, to observe whether the motor driver can quickly adjust the working state of the motor according to the algorithm when the load changes, and to evaluate the response performance of the driver. This test method can be said to be one of the most commonly used methods to determine whether the driver is aging.

2. Perform driver performance test

Driver performance test mainly focuses on driver efficiency, harmonic analysis, three-phase imbalance analysis, interference analysis and other test items. If these data are qualified, it means that they are not aging.
