+ | ====== Brushed DC Motor Control ====== | ||
+ | The Brushed DC motor is the simplest type of motor to control, all tht needs to be done is to vary the supply voltage and the motor' | ||
+ | |||
+ | A single transistor and diode can control the speed of a dc motor. | ||
+ | * The motor speed (voltage) is proportional to the transistor ON duty cycle. | ||
+ | * Positive torque only—passive braking. | ||
+ | An H-bridge power circuit enables four quadrant control | ||
+ | * Forward and reverse motion and braking | ||
+ | * Complementary PWM signals applied to the high and low side switches in the bridge | ||
