How to wire a Nema 23 stepper motor to a driver?
You need to figure out which wires make up the coil pairs. Here’s three ways to figure this out.
- You can use a multimeter and measure the resistance between the wires coming from the Nema 23 stepper motor. If you have a reading, it’s a pair. If not, it’s not a pair.
- In addition, if you don’t have a multimeter, turn the motor while touching the wires. Whichever combination makes it difficult to move the motor, it’s a pair.
- Of course, it’s not practical to sort out all possible combinations of connections with an ohmmeter or by feel. It is still easiest to connect the motor according to its datasheet. Assuming you don’t already have one, then read the model number off the motor and search online. You may need to contact the supplier to get the data sheet for the stepper motor.
