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.

Note: Connecting the motor directly to a power supply will destroy the motor and void the warranty. It must be used with a constant current / chopper drive controller such as a Phidget stepper 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.

Features

  • 30 kg-cm torque rating
  • 1.8 degree step angle
  • Rated for 4A of current
  • Connects to a Phidgets stepper controller

Connection

This motor must be controlled by a constant current or chopper drive controller. You can find a list of suitable controllers on the Connection & Compatibility tab. There you will also find compatible attachments such as encoders, mounting hardware, and transmission hardware.

Motor Controllers

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.

Pulleys and Sprockets

If you're using this motor to drive a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the motor. Pulleys and sprockets can also be used to transmit the motor's rotation over a long distance. For more guidance on building a transmission system, visit our Rotary Motion Guide. Here is a list of our 12mm bore pulleys and sprockets:

Rotary Bearings

Systems with heavy loads or pulley/sprocket assemblies often put a lot of sideways strain on the motor shaft. If you're using this motor to drive such a system, you can use rotary bearings to protect the motor:
