NEMA23 Geared Stepper Motor
The NEMA23 geared stepper motor features a frame size of 57 mm x 57 mm and combines an economy planetary gearbox with a NEMA23 stepper motor. They are available in 8 standard models and the maximum torque they can achieve is 13.5 kg.cm (189 oz-in). With reduction ratios spanning from 3:1 to 175:1, these motors offer output speeds ranging from 17 to 1000 rpm. The diverse gear ratios enable the motor to deliver enhanced torque and function at lower speeds, making it exceptionally well-suited for applications demanding precise control and substantial force.

FAQ
Q: What are some common issues with geared stepper motors?
A: Common issues with geared stepper motors include backlash (play in the gears), overheating due to prolonged use, missed steps resulting from excessive load or insufficient current, and noise during operation. Proper maintenance, selecting the right motor for the application, and addressing these issues can help improve performance.
Q: Do you have a minimum order quantity (MOQ) requirement?
A: Our minimum order quantity (MOQ) can vary depending on the product. Some items may have a specific MOQ, while others may be available for purchase in smaller quantities. Please contact our sales team for more information regarding the MOQ for the specific product you are interested in.
Q: Can you give me a discount?
A: Yes, discounts are available based on the quantity you order. Our pricing is competitive in the market, and the discount percentage will depend on the specific quantity. Please provide us with the actual quantity you require, and we can offer you the applicable discount accordingly.
Q: Can I run a geared stepper motor at a lower voltage than its rating?
A: Running a geared stepper motor at a lower voltage than its rating is generally not recommended. Doing so can result in reduced performance, insufficient torque, and potentially missed steps. It's essential to operate the motor within its specified voltage range to ensure proper functioning and avoid potential damage. If lower voltage operation is necessary, consider using a motor with a lower voltage rating.
