By Polarity
Bipolar
- The bipolar stepper motor has two coils (phases) with a single winding per phase and no center taps.
- Requires a complex driver circuit, often an H-bridge driver, to reverse the current through the coils.
Unipolar
- Unipolar stepper motor has two center-tapped coils, four windings, simpler circuitry for driving.
- Requires a simpler driver circuit, typically with a single transistor per winding.
By control system
Open-Loop
- No Feedback: Open-loop stepper motor operates without feedback, assuming the motor follows a predefined pulse sequence accurately.
- Control: Simple control scheme where the motor's position is determined by the number of input pulses.
Closed-Loop
- Feedback Mechanism: Closed-loop stepper motor uses sensors to monitor the motor's location, speed, and sometimes torque continuously.
- Control: Complex control system adjusts motor operation in real-time, ensuring precise position & speed.
Encoder Feedback
- Feedback Mechanism: Encoder stepper motor uses an encoder on the motor shaft to convert motion into electrical signals, providing precise position feedback.
- Control: The control involves using feedback from the encoder to adjust the motor's operation in real-time.
