Approximate arrival date of new stock: June 7, 2013
This NEMA-17 motor has an integrated Planetary gearbox with a 52/11 :1 ratio. It generates 16.2 Kg-cm of torque at 1.68 Amps.
When connected to a 1063 - PhidgetStepper Bipolar 1-Motor, the 3317 has a maximum speed of a little over 118 RPM. At the output of the gearbox, the step angle is a little under 0.35°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio.
This particular revision of the 3317 is made by a different manufacturer, but should behave very similarly to the revision 0 version.
The 3317 stepper motor connects to a bipolar motor controller:
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.
|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.|
