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.
