Product Features

This affordable bipolar stepper has a 1.8° step angle and 4.24 kg·cm of torque at low speeds.
Product Description

This motor is a larger NEMA-17 motor that produces a whopping 4800g-cm of holding torque. The motor is also very efficient in converting current into torque and velocity.

Motor Controller and Connection

The 3303 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.

Mounting Bracket

The mounting holes on this motor are compatible with the 3338 - Mounting Bracket (NEMA17).
