This NEMA-23 motor has an integrated Planetary gearbox with a 

76 49/64 :1 ratio. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler. See the “”Compatible Products”” tab for a complete list of attachments.

When connected to a 1067 – PhidgetStepper Bipolar HC, the 3334 has a maximum speed of 25 RPM. At the output of the gearbox, the step angle approximately 0.023В°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8В° by the gearbox reduction ratio. See the “”Compatible Products”” tab for wiring details.

At 2.8 Amps, this stepper motor can produce a maximum torque of 960 kg-cm. However, the gearbox is only rated for 240 kg-cm of continuous torque. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.

Connection

This motor must be controlled by a constant current or chopper drive controller. You can find a list of suitable controllers on the Compatible Productstab. 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.

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.

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