Q1:- In a single phase induction motor
- both the main and auxiliary windings are placed on the stator
- both the main and auxiliary windings are paced on the rotor
- the main winding is on stator and the auxiliary winding is on rotor
- none of the above
Q2:- The rotor windings of a synchro control transformer are
- never connected to the A.C. supply
- connected to the CT taps
- for 3-phase power input only
- connected to the A.C. supply
Q3:- The direction of rotation in a conventional shaded -pole motor can be reversed by
- reversing the line connections
- using a capacitor
- reversing the rotor
- reversing the stator poles 180 degree
Q4:- The effective voltage induced in any synchro transmitter coi depends on the angular position of the
- the differential field flux
- the A.C. magnetic field of the rotor
- a D.C. source
- compensation windings
Q5:- If the centrifugal switch of a capacitor start motor fail to open
- the motor will come to stop
- the auxiliary winding will be damaged the capacitor will be destroyed.
- the capacitor will be destroyed
- none of the above
