Product Description
The permanent magnet deceleration stepper motor is a type of motor that combines the advantages of a permanent magnet motor and a stepper motor. It is widely used in various industries due to its unique composition and excellent performance.
This motor consists of several essential components, including a permanent magnet rotor, a stator, a deceleration mechanism, and a control system. The permanent magnet rotor is a key element that generates the magnetic field required for the motor’s operation. It is composed of a series of permanent magnets with alternating polarities, which create a rotating magnetic field when energized. The stator, on the other hand, houses the windings that produce electromagnetic fields to interact with the rotor’s magnetic field. The deceleration mechanism, such as a gear system or a belt drive, is responsible for reducing the motor’s speed and increasing its torque. Lastly, the control system regulates the motor’s operation by providing precise electrical pulses to the windings, enabling accurate positioning and control.
1. The trapezoidal claw pole of stepper motors is stamped and extended, making it easy to manufacture and process;
2. The trapezoidal claw pole design is suitable for multi-pole structures, which not only reduces the step angle of the permanent magnet stepper motor, but also has high material utilization rate;
3. Since the number of claw pole teeth is equal to the number of rotor poles, the tooth harmonic torque is the second harmonic torque, and the two stators are offset from each other by 90° electrical angle, so the tooth harmonic torque amplitude of the two stators is equal and the phase is opposite. The result is zero.
