Electromagnetic Clutch Braking System with IR Sensor

This paper reveals the fabrication of Electromagnetic clutch braking system with IR sensor. Automotive vehicles are increasingly being equipped with collision avoidance and warning system for predicting collision with an external object, such as another vehicle or a pedestrian. Upon detecting a potential collision, such system typically initiates an action to avoid the collision and/or provide a warning to the vehicle operator. The braking system consists of IR transmitter and receiver circuit and the vehicle. The IR sensor is used to detect the obstacle. There is any obstacle in the path, the IR sensor senses the obstacle and giving the control signal to the microcontroller, which in turn send signal to the motor to stop and also to the solenoid so as to stop the vehicle as programmed. An electromagnetic clutch is a device used to make and brake contact from the transmission operate electrically but transmit torque mechanically. An electromagnetic braking system uses magnetic force to engage the brake but the power required for braking is transmitted manually. The disc is connected to a shaft and the electromagnet is mounted on the frame. The eddy current is created by the relative motion between a magnet and a metal (or alloy) conductor. The reverse magnetic field is induced which results in the deceleration of motion. This proposed the mechanism which implements this phenomenon in developing and electromagnetic clutch and braking system. This reduces complication to control of clutch and brakes.
