NEMA-11 Bipolar 32mm Mini Stepper

ID: 3300_0

This tiny bipolar stepper has a 1.8° step angle and 600 g·cm of holding torque.


Replaced by the 3320_0, the same motor with a rear shaft and encoder mounting holes.

This is a nice, small, efficient stepper motor with good torque characteristics.

The 3300 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.


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


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.

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