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!
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.
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.
