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.
This motor is particulary suited for precision applications due to its 0.9° step angle.
When connected to a 1067 - PhidgetStepper Bipolar HC, the 3340 has a maximum speed of 2344 RPM.
The 3340 stepper motor connects to a bipolar motor controller such as the 1067 - PhidgetStepper Bipolar HC.
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 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.
