NEMA17 Geared Stepper Motor
The NEMA17 geared stepper motor has a frame size of 42 mm x 42 mm and consists of an economy planetary gearbox with a NEMA17 stepper motor. Available in 7 standard models, the highest torque they can achieve is 6.9kg.cm/95.8 oz-in. Having a reduction ratio range from 3:1 to 225:1, their output speeds range is between 13rpm and 1000rpm. The various gear ratios, allows the motor to generate higher torque and operate at lower speeds, making it exceptionally well-suited for applications requiring fine control and substantial force.
- Fast Delievery
- Quality Assurance

FAQ
Q: What are the advantages of using a geared stepper motor?
A: Geared stepper motors offer enhanced torque, precise motion control, and reduced speed, making them ideal for applications requiring high torque at low speeds. They improve positioning accuracy, especially when combined with micro-stepping, and can compensate for backlash. Geared motors are energy-efficient, generate less heat, and often simplify mechanical designs. Their versatility and cost-effectiveness make them suitable for a wide range of applications, from robotics to 3D printers. Additionally, they require minimal maintenance due to their robust construction.
Q: Are there any safety considerations when using geared stepper motors?
A: Yes, safety is crucial when using geared stepper motors. Ensure proper electrical wiring, guard moving parts, control temperatures, implement emergency stops, perform regular maintenance, follow load limits, protect against interference, train operators, consider the environment, and adhere to relevant safety standards to prevent accidents and ensure safe operation.
Q: Can l visit your factory before placing the order?
A: Sure. You are most welcome to visit our factory.
