This motor is about half as small as our NEMA-17 Stepper and as a result only needs about half the power. Compared to the other NEMA-14 stepper we carry, it's a little longer but has the option to mount an encoder to the rear shaft!


Description [Hide]

Stepper motors are different from DC motors in that they have to be pulsed in set increments in order to move. That means you can't simply hook them up to a power supply to make them go, but they have other advantages, like accurate positioning (1 pulse=1 increment of movement), and lots of low-speed torque (ability to twist things). To control this type of motor you'll need a circuit that has 4 or more mosfets, a dual H-bridge, or a specifically designed stepper driver.

Product Features

  • Good torque and high speed
  • 1.8° Step angle
  • NEMA-14 bipolar 4-wire
  • Rear shaft exposed for use with encoders

The following table 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 yellow and blue wires.

  • Board Connector A is Black
  • Board Connector B is Green
  • Board Connector C is Red
  • Board Connector D is Blue

Please Note: 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.
