This NEMA-11 motor generates 600 g-cm of holding torque at 0.67 Amps. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler.

Note: Connecting the motor directly to a power supply will destroy the motor and void the warranty. It must be used with a constant current / chopper drive controller such as a Phidget stepper controller.

Features

520 g-cm torque rating
1.8 degree step angle
Rated for 0.67A of current
Connects to a Phidgets stepper controller

Connection

This motor must be controlled by a constant current or chopper drive controller. You can find a list of suitable controllers on the Connection & Compatibility tab. There you will also find compatible attachments such as encoders, mounting hardware, and transmission hardware.

Motor Controllers

This motor must be controlled by a stepper motor controller. This diagram shows how to connect the motor wires to the controller to produce a clockwise rotation in the stepper motor when increasing position. To wire for counter-clockwise rotation when increasing position, reverse the red and blue wires.

Note: Make sure to unplug the power cord from the motor controller before switching wires around.

Pulleys and Sprockets

If you're using this motor to drive a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the motor. Pulleys and sprockets can also be used to transmit the motor's rotation over a long distance. For more guidance on building a transmission system, visit our Rotary Motion Guide. Here is a list of our 5mm bore pulleys and sprockets:
