Product Features


This tiny stepper with a rear shaft has a 1.8° step angle and 520 g·cm of torque at low speeds.
 
Product Description

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.

When connected to a 1067 - PhidgetStepper Bipolar HC, the 3320 has a maximum speed of approximately 426 RPM.


Motor Controller and Connection


The 3320 stepper motor connects to a bipolar motor controller such as the 1067 - PhidgetStepper Bipolar HC.

The following diagram shows how to connect the motor wires to the board connectors 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.

Series

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


The rear shaft of this motor can be equipped with the HKT22 Optical Encoder for applications where you need to keep track of the exact position, velocity, or acceleration of the motor.
Connection

Mounting Bracket


The mounting holes on this motor are compatible with the 3337 - Mounting Bracket (NEMA11).
