4 Wire Bipolar Stepper Motor Wiring Diagram. Bipolar stepper motor wiring diagram wiring diagram is a simplified gratifying pictorial representation of an electrical circuit it shows the components of the circuit as simplified shapes and the talent and signal associates amid the devices. This wiring configuration is best suited for applications requiring high torque at relatively low speeds. In a 6 wire motor you have to find the outer leads and skip the center common leads of the coil.
If your stepper motor has 4 wires it is a bipolar stepper motor. There are slight differences on how the different variant of stepper motors work i e. This is a datasheet of a nema 17 6 wire which can be connected as bipolar or as unipolar. If not the structure won t function as it should be.
Speaking specifically of holding torque the datasheet shows that if you turn the motor on a unipolar driver it loses 30 of the torque.
If your stepper motor has 4 wires it is a bipolar stepper motor. Wiring the motor in bipolar configuration is probably the easiest. This shows that the stepper motor in general starts at a low rpm and the torque decreases as the speed increases. It is not realistic to sort out all of the possible combinations of connections with an ohmmeter or by feel. Stepper motors with these center taps are often referred to as unipolar motors.
