Stepper motor, also known as pulse motor, based on the most basic principle of electromagnet, it is a free rotation of the electromagnet, the action principle is to rely on changes in air gap to produce electromagnetic torque.
1. Excellent loadability. Its speed is not affected by the size of the load
2. Easy to control. Stepper motor is "step" as a unit of rotation, the digital features more obvious.
3. The whole structure is simple. The speed motor converts the speed into a voltage and passes it to the input as a feedback signal. The speed motor is a kind of auxiliary motor.
