3324_0 42STH38 NEMA-17 Bipolar Gearless Stepper
£22.20 £18.50
This NEMA-17 motor generates 3.6 Kg-cm of holding torque at 1.7 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, the 3324 has a maximum speed of 4130 RPM
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.
The mounting holes on this motor are compatible with the 3338 - Mounting Bracket (NEMA17).
