The third pin accepts PWM (Pulse-Width Modulation) control signals, compatible with microcontrollers and Arduino boards. This signal determines the motor's rotation angle through varying pulse lengths, offering simpler control compared to stepper motors.
The system uses a deviation counter to compare external pulse signals with encoder feedback. During operation, accumulated pulses (positioning deviation) are generated and controlled to reach zero, enabling precise position holding through servo control.
Common in smaller unipolar motors with internally connected common coil wires. This configuration operates exclusively as a unipolar motor.
Features joined common wires of two paired phases. Can be configured as a 5-wire unipolar motor or operated as a standard bipolar motor.
The most versatile configuration supporting multiple drive methods: 4-phase unipolar, 2-phase series bipolar, and 2-phase parallel bipolar. Parallel bipolar wiring provides higher torque and speed capabilities despite requiring double the current.
