H Bridge Driver Dc Motor. The direction can be changed easily and the speed can be controlled. Role of h bridges in driving motors a dc motor direct current motor is a motor which rotates when a voltage is applied at its terminals.
It is the simple and elegant solution to all motor driving problems. From a simple vibration motor inside a mobile phone to complex stepper motors in cnc machines these dc machines can be found everywhere. H bridge is a simple electronic circuit which enables us to apply voltage to load in either direction.
The direction can be changed easily and the speed can be controlled.
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. The speed of the motor is proportional to the voltage and direction is dependent on the polarity direction of current. An h bridge full bridge driver is quite popular in driving loads such as brushed dc motors and it is widely used in robotics and industry. High efficiency rotation direction change and braking the motor.
