The equivalent circuit of a single-phase single winding induction motor with the standstill rotor is shown below. The forward and the backward flux induces a voltage E mf and E mb respectively in the main stator winding. E m is the resultant induced voltage in the main winding. Now, with the help of an auxiliary winding, the motor is started.

EE Laboratory Experiment 6 Single Phase Induction Motors Answer the following questions. 3. How can the direction of rotation of a split-phase or capacitor-start induction motor be reversed? 4. Compare capacitor start and capacitor run motor with respect to (i) starting torque, (ii) power factor at rated speed. (Answer either high or low.).

3. To study the different starting methods of 3-phase induction motors also study how to reverse the direction of rotation in a 3-phase induction motor. 4. To perform no load test on a three phase induction motor to find out its performance parameters with the help of Equivalent circuit 5. Exercise 1 - Operation and Characteristics of Single-Phase Induction Motors In step 22 of this exercise, the voltage control knob must be set higher than 50%. Also, the circuit breaker protecting the Capacitor-Start Motor trips after very short time intervals. similar lines as that of a transformer’s. The equivalent circuit for a single-cage induction machine is shown in Fig.(1). Here, (R 0 r + R 0 r (1 s s)) + jX r1 represents the rotor circuit impedance as a function of slip s.
