3302_0 - NEMA-17 Bipolar 48mm Stepper (0.9° Step Angle) - Discontinued

Product Features

This precise bipolar stepper has a 0.9° step angle and 4.28 kg·cm of torque at low speeds.

Replaced by the 3340_0, the same motor with a rear shaft and encoder mounting holes.

Product Description

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

Motor Controller and Connection

The 3302 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).


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.
