Single Phase Stepper Motor is permanent magnet stepper drive motor, it achieves precise angular positioning by pulse signals. Widely used in automation equipment, office machines, small instruments and valve actuators. This single phase stepper motor features compact structure and stable open-loop positioning, it is popular micro stepper motor for light-load automation projects.

Fixed step angle for accurate positioning
Our Single Phase Stepper Motor has stable fixed step angle. It rotates preset angle once receiving one pulse signal, no position feedback sensor required. It ensures reliable positioning of single phase stepper motor at low speed, ideal for small automation machines requiring fixed start-stop points.
Permanent magnet rotor with compact mini size
Single Phase Stepper Motor adopts permanent magnet rotor design, small dimension and light weight as micro stepper motor, saving installation space, widely adopted inside compact instruments as single phase stepper motor.
Controllable unidirectional rotation with simple control logic
Single Phase Stepper Motor has only single phase winding with simple drive circuit. Engineers can finish wiring and commissioning quickly, reducing design difficulty of full stepper motor control system.

Open-loop operation to cut system cost
Single Phase Stepper Motor controls position directly via pulse signals without encoder or feedback parts. It lowers component and assembly cost, becomes preferred single phase stepper motor for automation projects with limited budget.
Holding torque keeps shaft locked at standstill
Single Phase Stepper Motor generates holding torque when powered and static. It locks output shaft without extra brake parts, preventing position shift of stepper motor and improving machine stability.
Brushless design, long service life and low maintenance
Single Phase Stepper Motor has no brush wear, low operation loss and low failure rate. Only simple visual inspection needed for long-term running, cutting later maintenance work of single phase stepper motor.
