Although the overall stepper motor is not as good as the servo motor, but the price is relatively cheap, many areas are also sufficient, is still relatively popular, the technology is also increasingly advanced.
Its working principle is to convert the electrical pulse signal into the corresponding angular or linear displacement when operating. When the pulse signal is input, the motor rotor will rotate an angle or take a step forward, the displacement is the number of pulses input, and the rotation speed is proportional to the pulse frequency. Stepper motor is often called pulse motor. After a period of time, stepper motor will also be aging like other mechanical equipment. So how can you tell when a stepper motor is aging? What are the methods.
1. Stepper motor driver response test
Use the motor test bench to apply different loads on the motor, pay attention to the load changes in the motor driver, adjust the working state of the motor, while judging the responsiveness of the driver. This is also a common method to determine whether the stepper motor is aging.
2. Test the performance of the motor driver
When testing the performance of the motor driver, mainly analyze the harmonics, the efficiency of the motor and the three-phase unbalance and interference capability situation. If the data analyzed meet the standard, it means that the stepper motor does not have aging problems.
These are the methods often used to determine the aging phenomenon of stepper motors, master these basics in order to better check the stepper motor, to ensure its normal operation.
