Phidgets 35STH40 NEMA 14 Bipolar Gearless Stepper 3323_0
This NEMA-14 motor generates 1.4 Kg-cm of holding torque at 1 Amp. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler. See under Connection & Compatibility for a complete list of attachments.
Connection
This motor must be controlled by a constant current or chopper drive controller. You can find a list of suitable controllers under Connection & Compatibility. There you will also find compatible attachments such as encoders, mounting hardware, and transmission hardware.
Warning
Connecting the motor directly to a power supply will destroy the motor and void the warranty. If you want to check your motor make sure it is connected to a constant current / chopper drive controller.

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.
