This NEMA23 motor has an integrated Planetary gearbox with a 15 ^{3}/_{10 } :1 ratio. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler. See the Connection & Compatibility tab for a complete list of attachments.
When connected to a 1067  PhidgetStepper Bipolar HC, the 3333 has a maximum speed of 116 RPM. At the output of the gearbox, the step angle is approximately 0.12°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio. See the Connection & Compatibility tab for wiring details.
At 2.8 Amps, this stepper motor can produce a maximum torque of 192 kgcm. However, the gearbox is only rated for 150 kgcm of continuous torque. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.
Connecting the motor directly to a power supply will destroy the motor and void the warranty. 
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 counterclockwise 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.

The following stepper controllers can be used to drive this motor:

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 Primer. Here is a list of our 12mm bore pulleys and sprockets:

Systems with heavy loads or pulley/sprocket assemblies often put a lot of sideways strain on the motor shaft. If you're using this motor to drive such a system, you can use rotary bearings to protect the motor:
