1.Working principle

The variable reluctance stepper motor uses the change of magnetic resistance to generate torque and is a special stepper motor. Its rotor is equipped with multiple pole pairs, each of which is made of magnetic material. The coil on the stator generates a magnetic field through current, and the direction and size of the magnetic field can be controlled by changing the direction and size of the current. When the magnetic field of the stator approaches or reaches the polar magnetic material, the material will be magnetized to become magnetically conductive, so that the rotor generates torque and the stepper motor will rotate.

2.Characteristics

1.High performance: The variable reluctance stepper motor has high rotation accuracy, strong reliability, smooth operation and low noise.

2.High efficiency: Due to the particularity of its working principle, the variable reluctance stepper motor consumes low energy when starting, stopping and decelerating.

3.Strong load capacity: The variable reluctance stepper motor has stable torque output and can work under high load.

4.Simple control: The control method of the variable reluctance stepper motor is simple. You only need to master the direction and size of the current to control the angle and speed of the motor.

3.Application fields

Variable reluctance stepper motors are widely used in industrial automation, medical equipment, printing equipment, robots and other fields. Its high precision, high efficiency, high load capacity and other characteristics make it widely used in various automatic control systems. As an important type of motor, reluctance stepper motors are widely used in the field of automatic control. Its structural characteristics are mainly reflected in the stator, rotor, magnetic pole distribution, etc., and precise position control and motion control are achieved by reversing the direction of current.

4.Summary

Compared with other types of stepper motors, variable reluctance stepper motors have the advantages of fast speed, low noise and simple control. However, compared with servo motors with good speed regulation performance, variable reluctance stepper motors have the disadvantages of narrow speed adjustment range and poor speed stability. Therefore, they need to be selected according to the actual application scenario.
