Motor Driver Circuit Design

Figure 2 shows actual size single side pcb design for the bldc motor driver circuit.

Motor driver circuit design.

But thanks to valuable comments from instructables users who suggested me to use pwm pins to control motor speed and to improve the circuit. In this project we will make an 8 channel motor driver module circuit for motors based applications. By using this motor driver board we can operate 8 dc motors or four 4 wire stepper motors at a time. If input1 is logical 1 and input2 is logical 0 the motor on the left of the schematic will rotate.

In this circuit we have designed a pcb for driving dc or stepper motors. Here s an interesting bit. So this circuit. A stepper motor driver or stepper motor drive is a circuit which is used to drive or run a stepper motor.

It is the simple and elegant solution to all motor driving problems. Figure 3 depicts component layout for the same. In this instructable we ll be making our own motor driver using transistors. A stepper motor driver is a circuit that takes the pulse signals from a controller and converts them in to stepper motor motion.

This is normal functioning of the chip. The h bridge motor driver circuit this circuit is called h bridge because the mosfets form the two vertical strokes and the motor forms the horizontal stroke of the alphabet h. In my last attempt to use transistor as motor driver i was unable to control the speed of the motor using it. As shown in the bldc motor driver circuit place all the components in the assigned order and avoid any possible errors which may degrade the implementation process.

It is often called a stepper motor driver. In this project we have designed a simple 12v stepper motor driver circuit using 555 timer ic acting as a controller a cd4017 decade counter acting as the driver along with few other components. A stepper motor driver usually consists of a controller a driver and the connections to the motor. Construction of bldc motor driver circuit.
