           TASK 3 : Start & run of DC Shunt motor
           1  Make the connections of DC shunt motor with 3 point starter as per circuit diagram.
           2  Ensure that there is no mechanical load on the motor (Do not start DC shunt motor with load).
           3  Check the connections & connect the motor to DC power supply unit through DPST switch.
           4  Start the motor by operating DC 3 point starter.

           5  Record the starting & running current, voltage and speed of the motor.
           6  Now apply the mechanical load gradually on the motor and check the speed of motor by tacho meter. (Note- do
              not over load the motor as shunt motor is not capable to heavy load).

           7  Switch OFF the supply and disconnect the motor.
