Includes protection schemes to prevent the failure of motors due to any faults.The motor can be a brushless DC motor, brushed DC motor, stepper motor, other DC motors etc. This high current signal is then given to the motor. The function of the circuit is to convert the low current signal to a high current signal. The input to the motor driver IC or motor driver circuit is a low current signal.
#L293D MOTOR DRIVER CIRCUIT DRIVERS#
Motor drivers are made from discrete components which are integrated inside an IC. They act as a bridge between the controller and the motor in a motor drive. Motor Driver circuits are current amplifiers. If there are multiple servo motors then PIC, ATMEGA etc. Usually, 8051 controllers are used for controlling a servo motor driver with a single servo motor. The major motor drive components for a servo motor are a controller, power supply unit, servo motor and the necessary connections with the motor.Ĭommonly, motor drive for a servo motor is also known as Servo motor controller or Servo Motor Driver. Servo motor is a type of actuator device that consists of a motor and a sensor to control velocity, acceleration etc. Power Supply Unit: Provides the required power to the motor drive.While stepper motor is a brushless DC electric motor that converts electrical pulses into discrete mechanical motions. In a brushless DC motor, it consists of a DC power source, an inverter producing an AC signal to drive the motor. DC motor is a type of motor that can convert DC into a mechanical power. While interfacing with the controller some of the motors like DC motor, stepper motor and brushless dc motor may require a driver IC or driver circuit. Motor: Motor is defined as an electric or mechanic device that can create a motion.Motor Driver IC or Motor Driver Circuits: They are basically current amplifierswhich accept the low current signal from the controller and convert it into a high current signal which helps to drive the motor.Controller: The controller can be a microprocessor or a microcontroller.The major motor drive components for DC motors are: a controller, a motor driver IC or a motor driver circuit, the desired DC motor being used, power supply unit and the necessary connections to the motor. These drive circuits can be easily interfaced with the motor and their selection depends upon the type of motor being used and their ratings (current, voltage). In other words, they are commonly used for motor interfacing. Motor drives are circuits used to run a motor.
