This motor is a about half as small as our NEMA-17 stepper and as a result only needs about half the power. The NEMA-14 Stepper is very efficient in converting current into torque and velocity, and is great if you need to fit a stepper in a smaller area.
Please Note: we have only one left in stock. The replacement motor is 33606.
Stepper motors are different from DC motors in that they have to be pulsed to move in set increments. 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.
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.
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.
