Product Overview
The NFP-0620-531-MG is a 6mm planetary step gear motor with a 530.842:1 reduction ratio. Therefore, it is suitable for compact products that need precise step motion, low speed, and high torque output.
In addition, the motor uses a 4-stage metal planetary gearbox. As a result, it can provide strong output in a very small size.
Moreover, this model works with 5V DC rated voltage and a 3V to 7V voltage range. Therefore, users can test it with common low-voltage stepper motor driver systems.
Main Features
