Tips: How to solve the problem about heating of the stepper motor?
- Reducing heating of the motor means reducing copper and iron loss. There are two directions for reducing the copper loss, including reducing resistance and current. It is thus required to choose the motor with small resistance and rated current when selecting the motor. As for 2-phase motor, the parallel cannot be used if the series one could be used. However, it usually collides against the requirements of torque and high velocity.
- As for the selected motor, it is necessary to make full use of automatic semi-flow control and offline state functions of the stepper motor driver, as for former of which the current will be reduced when the motor is at static state while as for the latter of which the current is cut off.
- In addition, as the current waveform approaches the sine and has less harmonic wave, the heating of motor with subdivided driver is less. There are few methods or reducing the iron loss. It is related to the voltage grade. Though high voltage driver motor could lead to the rise in high speed characteristic, the increase in heating is also brought.
- It is necessary to choose drive motor with proper voltage grade, giving considerations into indexes such as stability, heating and noise, etc.
