Project 1

Aim:

To develop a PWM controlled fanload with DC motor.

Blocks used

H-bridge

It is used as controller to controll the dc motor according to the gate pulses applied by Controlled PWM generator.

Controlled PWM generator

It is used to provide the gate pulses to the Hbridge

Dc motor

Dc motor is used to rotate the fan.

Aero dynamic drag:

Aerodynamic drag is used to provide the necessary aerodynamic drag to the fan while rotating.

Working:

Here the required gate pulses are produced by the controlled pwm generator.The controller control the motor and the corresponding output is observed.output torque and output speed are observed.
