Product Description
This motor is a larger NEMA-17 motor that produces a whopping 4800g-cm of holding torque. The motor is also very efficient in converting current into torque and velocity.
Motor Controller and Connection
The 3303 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.
| Wire Color | Black | Green | Red | Blue |
| Board Connector | A | B | C | D |
Note: Make sure to unplug the power cord from the motor controller before switching wires around.
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. |
