This NEMA-34 motor generates 34 kg-cm of holding torque at 2.8 Amps. It comes with the rear shaft exposed, so you can mount anencoder or shaft coupler.

When connected to a 1067 - PhidgetStepper Bipolar HC, the 3335 has a maximum speed of 200 RPM.

The 3335 stepper motor connects to a bipolar motor controller such as the 1067 - PhidgetStepper Bipolar HC.

The following diagrams show two connection methods: series and parallel.

Series Parallel

Series wiring will result in higher torque when the motor is stopped or at low speeds. Parallel wiring will provide better torque at higher speeds, but less torque overall. Since the current in parallel mode is split between two paths, the current rating is doubled.

When connecting motor wires to one another, you must solder or screw clamp them together rather than just twisting them together.

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

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.

This motor is large enough that the back EMF generated from stalling or changing directions could easily damage your motor controller. If you're planning on using this motor in high-speed or high-torque applications, feel free to contact us for advice.
