In case of a shaded pole motor the direction of rotation of the motor is
A). from main pole to shaded pole
B). from shaded pole to main pole
C). either of the above depending on voltage
D). either of the above depending on power factor
The rotor slots, in an induction motor, are usually not quite parallel to the shaft because it
A). improves the efficiency
B). helps the rotor teeth to remain under the stator teeth
C). helps in reducing the tendency of the rotor teeth to remain under the stator teeth
D). improves the power factor
