The Phidgets NEMA-11 Bipolar Gearless Stepper Motor generates 600 g-cm of holding torque at 0.67 Amps. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler. When connected to a 1067 – PhidgetStepper Bipolar HC controller, the 3320 has a maximum speed of approximately 426 RPM.
The 3320 stepper motor connects to a bipolar motor controller such as the 1067 – PhidgetStepper Bipolar HC controller. The following diagram 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 red and blue wires.
Note: Make sure to unplug the power cord from the motor controller before switching wires around. The rear shaft of this motor can be equipped with the HKT22 Optical Encoder for applications where you need to keep track of the exact position, velocity, or acceleration of the motor. Warning 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.
