What is a stepper gear motor?

A stepper gear motor combines a stepper motor with a reduction gearbox to increase torque, improve positioning accuracy, and provide stable low-speed motion. It is ideal for applications that require precise control and high torque in a compact form factor.

How does a gearbox improve the performance of a stepper motor?

The gearbox multiplies torque and reduces output speed, allowing the stepper motor to drive heavier loads while maintaining precision. It also decreases step angle, resulting in smoother motion and higher positional resolution.

What torque levels can your stepper gear motors achieve?

Torque output depends on gearbox ratio and motor size. As a manufacturer, we can provide custom torque ranges, from small micro-geared steppers to high-torque industrial units. Send your load requirements for exact recommendations.

Can I customize shaft size, gearbox ratio, or wiring?

Yes. As a manufacturer, we offer full customization including: Gear ratios, Output shaft shape (D-shaft, round, threaded, hollow), Cable length & connectors, Step angle and coil impedance, Mounting holes & flanges, Customization ensures compatibility with your device and performance targets.

What is the typical lifespan of a stepper gear motor?

Lifespan depends on load, gearbox type, lubrication, and duty cycle. Under normal conditions, quality stepper gear motors offer 5,000–20,000 hours of service life. Metal gearboxes and planetary designs provide higher durability.

Are stepper gear motors noisy?

Noise comes mainly from the gearbox. Spur gearboxes are louder, while planetary and worm designs reduce noise. We can optimize noise performance through gear material, lubrication, and precision machining.

What is the maximum speed of a stepper gear motor?

Gear reduction limits output speed, typically 5–500 RPM depending on ratio. Stepper motors without gearboxes can run faster, but geared versions are optimized for high torque at low speed.
