   	- Tips: Which types of stepper motor is divided into?
- Stepper motor is divided into three types: permanent magnet stepper motor (PM), variable reluctance stepper motor (VR) and hybrid stepper motor (HB).
- 1. PM stepper motor is generally 2-phase, with small torque and volume, its stepping angle is generally 7.5° or 15°.
- 2. VR stepper motor is generally 3-phase; high torque output can be realized; the stepping angle is generally 1.5, but the noise and vibration is large. The rotor magnetic circuit of VR stepper motor is made of soft magnetic materials. There is multi-phase exciting winding on the rotor. The torque is generated by taking advantage of the change in magnetic conductance.
- 3. HB stepper motor, indicating mixing the advantages of PM and VR, is divided into 2-phase, 3-phase and 5-phase. The stepping angle of 2-phase is generally 1.8°, that of 3-phase 1.2° and that of 5-phase is 0.72°. It is mostly widely applied.

Advantages of Stepper Motor:
   	- 1. The rotation angle of the motor is proportional to the input pulse.
- 2. The motor has full torque at standstill.
- 3. Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3 – 5% of a step and this error is noncumulative from one step to the next.
- 4. Excellent response to starting, stopping, and reversing.
- 5. Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.
- 6. The motor’s response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
- 7. It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
- 8. A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
