25mm PM stepper motor Features & Advantage：
1. High precision positioning
Since steppers move in precise repeatable steps, they excel in applications requiring precise
positioning, by the number of steps the motor moves
2. High Precision speed control
Precise increments of movement also allow for excellent control of rotational speed for process
automation and robotics. The rotational speed is determined by the frequency of the pulses.
3. Pause and holding function
With control of the drive, the motor has lock function (there is current through motor windings, but
the motor does not rotate), and there is still a holding torque output.
4. Long life & low electromagnetic interference
The stepper motor has no brushes, and does not need to be commutated by brushes like a brushed
DC motor. There is no friction of the brushes, which increases the service life, has no electric sparks, and reduces electromagnetic interference.
Working principle of stepper motor:
The drive of the stepper motor is controlled by software. When the motor needs to rotate, drive will
apply the stepper motor pulses. These pulses energize stepper motor’s in a specified order, thereby
causing the motor’s rotor to rotate in a specified direction (clockwise or counter clockwise). So as to
realize proper rotation of the motor. Each time the motor receives a pulse from the driver, it will rotate by a step angle (with full-step drive), and the rotation angle of the motor is determined by the number of driven pulses and step angle.
