This NEMA-17 motor has an integrated Planetary gearbox with a 52/11 :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 3325 has a maximum speed of approximately 900 RPM. At the output of the gearbox, the step angle is a little under 0.35?°. 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 “Compatible Products” tab for wiring details.

At 1.7 Amps, this stepper motor can produce a maximum torque of 18.6 kg-cm. However, the gearbox is only rated for 18 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

FUNCTIONAL

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:

 

 

Encoders

The rear shaft of this motor can be equipped with an encoder for applications where you need to keep track of the exact position, velocity, or acceleration of the motor. The mounting holes on the back of this motor are compatible with the following encoders:

 

Shaft Couplers

If you need to connect the main shaft of this motor to the shaft of another device, you can use a shaft coupler:
