• 86STH65 NEMA-34 Bipolar Gearless Stepper


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 an encoder or shaft coupler. See the "Compatible Products" tab for a complete list of attachments.

When connected to a 1067 Steppercontroller  the 3335 has a maximum speed of 200 RPM. This motor must be controlled by a constant current or chopper drive controller.

Motor Controllers

Series Series

This motor must be controlled by a stepper motor controller. These diagrams show to wiring configurations: series and 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.
