DESCRIPTION

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). The flip side is that they are power-pigs, but ya gotta love this sort of pig!

Sourced by Phidgets, this larger 3324 NEMA-17 stepper motor produces a 3600g*cm (49.99in*oz) of holding torque. 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.

If you're connecting it to a 1063 - PhidgetStepper Bipolar 1-Motor or similar controller, use this table to connect the motor wires to the board connectors to get clockwise rotation. To wire for counter-clockwise rotation, swap the Red 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.

Wiring Guide

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

Note: This is not the internal wiring of the stepper which is usually has A & C and B & D labels tied together, but to be clear the Black & Green wires are connected to one coil in the motor and Red and Blue the other. Datasheet available under documentation tab.
