Ac Stepper Motor
Characterized by high-voltage/high-power capabilities, constant torque at high speeds, strong interference resistance, direct mains compatibility, and stable 24-hour continuous operation, these AC stepper motors serve as core drive components for heavy-duty automation, large-scale CNC equipment, and long-cycle assembly line operations. Our entire AC stepper motor lineup has undergone rigorous third-party testing; the specifications are authentic and traceable, certifications are comprehensive, and batch consistency is high. Suitable for both domestic and international industrial high-voltage power environments, these motors represent the ideal solution for high-power, precision positioning equipment.

- Direct High-Voltage Mains Input & Simplified Wiring: Supports direct drive from AC 110V/220V industrial mains, eliminating the need for bulky, high-power DC switching power supplies. This simplifies the control cabinet layout, reduces wiring costs and potential points of failure, and aligns with standardized factory high-voltage power infrastructure, significantly boosting installation and commissioning efficiency.
- High-Speed Constant Torque without High-Speed Roll-off: Leveraging AC magnetic field drive characteristics, it delivers over 40% higher torque retention at high speeds compared to DC stepper motors. It effectively eliminates issues such as power loss, step loss, and vibration during high-speed operation, ensuring stability for continuous medium-to-high-speed feeding and prolonged constant-speed tasks.
- High Power & Heavy-Duty Capability: Optimized high-voltage windings and magnetic circuit structures provide a wider power range and robust output. Capable of driving high-inertia loads-such as heavy-duty slide tables, large indexing tables, and gantry drive mechanisms-it ensures smooth start-stop performance under heavy loads without stalling or positional deviation.

Q1: Can an AC stepper motor be connected directly to 220V AC power?
A1: It cannot be operated by connecting it directly to the power supply; it must be used with a compatible high-voltage stepper driver.
Q2: Do AC stepper motors lose steps at high speeds?
A2: Industrial-grade AC stepper motors effectively eliminate this issue. Leveraging the advantages of high-voltage driving, the motor exhibits no significant torque drop-off in the high-speed range of 0–2000 rpm; when paired with micro-stepping drives, it ensures precise positioning without step loss or positional drift.
Q3: What type of driver is required for an AC stepper motor? Can a standard driver be used?
A3: It requires a dedicated stepper driver designed for AC 220V high-voltage input; a low-voltage DC driver cannot be used as a substitute.
