Fabulous 6 Wire Stepper Motor Driver Circuit
A stepper motor can operate in many modes like full step wave drive or half stepping please refer the article on stepper motor for the sequence of steps.
6 wire stepper motor driver circuit. I have a 6 wires stepper motor. This motor uses six wires. Most national instruments stepper motor interfaces do not support 6 wire stepper motors although some motors do not require the center.
This shows that the stepper motor in general starts at a low rpm and the torque decreases as the speed increases. And i used a meter to measure their resistance and divided them into 2 groups. If not the structure won t function as it should be.
In a 6 wire motor you have to find the outer leads and skip the center common leads of the coil. The way that we can determine which wire this is his by. This is because of the way stepper motors are made stepper motors will have two coils and since this motor has six wires that means there are 3 wires per coil.
Wiring the motor in bipolar configuration is probably the easiest. This wiring configuration is best suited for applications requiring high torque at relatively low speeds. And hence this stepper motor driver circuit is essentially a binary counter circuit.
The measurements are as follows 1 2 wires 0 5 ohm 1 3 wires 2 5 ohm 2 3 wires 2 5 ohm 4 5 wires 2 5 ohm 4 6 wires 2 5 ohm 5 6 wires 0 5 ohm. It is a unipolar type stepper motor with 5 wire configuration. Most 6 wire stepper motors can be used in unipolar or in bipolar configuration.
Most stepper motors come with four six or eight wires. This third wire is commonly referred to as the phase s center tap. Basically stepper motors are classified in to unipolar stepper motors and bipolar stepper motors based on the windings of the stator.
