Explain the steps of the stepper motor!
Stepper motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. It is the main actuator in modern digital program control systems and is widely used. In the case of non-overload, the speed and stop position of the motor depend only on the frequency of the pulse signal and the number of pulses, and are not affected by the load change. When the stepper driver receives a pulse signal, it drives the stepper motor. The set direction is rotated by a fixed angle called the "step angle" whose rotation is performed step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses to achieve the purpose of accurate positioning. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, thereby achieving the purpose of speed regulation.
Main classification
Stepper motors can be divided into reactive stepping motors (VR), permanent magnet stepping motors (PermanentMagnet, PM), hybrid stepping motors (Hybrid Stepping, HS), single-phase stepping motors, Plane stepper motors and many other types.
Wiring
The difference between the four-wire lead-out and the six-wire lead-out is the flexibility of the connection to the drive. Two-phase four-wire stepper motors can only use bipolar drivers.
A two-phase, six-wire stepper motor can use either a bipolar driver or a unipolar driver.
