Project 1

output: 

torque vs speed

In this system, the input is provided by a voltage controlled source using a pulse generator. It then goes to the PWM pulse generstor and then passes to H bridge. From there, DC voltage is fed into a DC motor. A torque source and a motion sensor is used for the detection of rotation of fan. The angular speed is square of the torque generated in the fan load. hence the output can be derived and torque speed characteristic is shown.
