Frequently Asked Question
1.How to reduce the heat of the stepper motor:
Reduce heat generation is to reduce copper loss and iron loss. Reduce copper loss in two directions, reduce resistance and current, which requires the selection of small resistance and rated current as small as possible when the motor, the two-phase motor, can use the motor in series without parallel motor. But this often contradicts the requirements of torque and high speed. For the selected motor, the drive's automatic half-current control function and offline function should be fully utilized, the former automatically reduces the current when the motor is at rest, and the latter simply cuts off the current. In addition, the subdivision drive, because the current waveform is close to sinusoidal, less harmonics, motor heating will also be less. There are few ways to reduce iron loss, and the voltage level is related to it. Although a motor driven by high voltage will bring an increase in high-speed characteristics, it also brings an increase in heat generation. So we should choose the right drive voltage level, taking into account the high speed, smoothness and heat, noise and other indicators.
2.Principle of stepper motor:
The speed of a stepper motor is controlled with a driver, and the signal generator in the controller generates a pulse signal. By controlling the frequency of the pulse signal sent, when the motor receives a pulse signal will move one step (we only consider the whole step drive), you can control the speed of the motor.
3.What factors affect the speed of a stepper motor?
The speed of a stepper motor is determined by the driver frequency, the step angle of the stepper motor and the gearbox.
