Most national instruments stepper motor interfaces do not support 6 wire stepper motors although some motors do not require the center. A 12v stepper motor is used in this project. Now as shown in the circuit diagram the 555 circuit here is to generate clock or the square wave. The frequency of clock generation in this case cannot be kept constant so we need to get variable speed for the stepper motor. The outer leads will have the most resistance so just measure the resistance of different wire pairs. I have a 6 wires stepper motor. Most stepper motors come with four six or eight wires. Each component should be set and connected with different parts in particular manner. Hence we must make the driver interactive enough to be able to take command from the user and do the required kind of stepping.

The frequency of clock generation in this case cannot be kept constant so we need to get variable speed for the stepper motor. A 6 wire stepper motor is similar to a 4 wire configuration with the added feature of a common tap placed between either end of each phase as shown in figure 2. Wiring the motor in bipolar configuration is probably the easiest. Now as shown in the circuit diagram the 555 circuit here is to generate clock or the square wave. Stepper motors with these center taps are often referred to as unipolar motors. The following image shows a bipolar stepper. I have a 6 wires stepper motor. Most 6 wire stepper motors can be used in unipolar or in bipolar configuration. And i used a meter to measure their resistance and divided them into 2 groups. What we need to do is measure the resistance from one motor wire to another.
And hence this stepper motor driver circuit is essentially a binary counter circuit. It is a unipolar type stepper motor with 5 wire configuration. Hence we must make the driver interactive enough to be able to take command from the user and do the required kind of stepping. If not the structure won t function as it should be. The figure shows the circuit diagram of two stage stepper motor driver. Wiring the motor in bipolar configuration is probably the easiest. A 12v stepper motor is used in this project. Stepper motor driver circuit diagram and explanation. Each component should be set and connected with different parts in particular manner. This is a datasheet of a nema 17 6 wire which can be connected as bipolar or as unipolar.
It is a unipolar type stepper motor with 5 wire configuration. 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. The frequency of clock generation in this case cannot be kept constant so we need to get variable speed for the stepper motor. What we need to do is measure the resistance from one motor wire to another. Most national instruments stepper motor interfaces do not support 6 wire stepper motors although some motors do not require the center. This third wire is commonly referred to as the phase s center tap. A 12v stepper motor is used in this project. Speaking specifically of holding torque the datasheet shows that if you turn the motor on a unipolar driver it loses 30 of the torque. Hence we must make the driver interactive enough to be able to take command from the user and do the required kind of stepping. Most stepper motors come with four six or eight wires.
Now as shown in the circuit diagram the 555 circuit here is to generate clock or the square wave. Hence we must make the driver interactive enough to be able to take command from the user and do the required kind of stepping. The outer leads will have the most resistance so just measure the resistance of different wire pairs. It is a unipolar type stepper motor with 5 wire configuration. Basically stepper motors are classified in to unipolar stepper motors and bipolar stepper motors based on the windings of the stator. Speaking specifically of holding torque the datasheet shows that if you turn the motor on a unipolar driver it loses 30 of the torque. The way that we can determine which wire this is his by. This third wire is commonly referred to as the phase s center tap. If not the structure won t function as it should be. The following image shows a bipolar stepper.
