Q1:- When both synchro transmitter and receiver rotors are displace from zero by the same angle they are in
Q2:- capacitor start capacitor run motor is generally coupled with the air conditioner compressor because it
Q3:- A capacitor start capacitor run motor has two capaciotrs. when the motor is started
Q4:- By pushing and pulling the rotor shaft a motor can be checked for
- correspondence
- phase
- error
- unbalanced field synchronism
Q2:- capacitor start capacitor run motor is generally coupled with the air conditioner compressor because it
- takes low starting as well as running current
- is cheaper
- is quit in operation
- does not require any maintenance
Q3:- A capacitor start capacitor run motor has two capaciotrs. when the motor is started
- only one of the capacitors is in circuit
- both the capacitors are circuit and are connected in parallel
- both the capacitors are in circuit and are connected in series
- both are in series
Q4:- By pushing and pulling the rotor shaft a motor can be checked for
- end play
- side play
- firm mounting
- free shaft movement
ANSWER:-1

- bar to bar
- voltage drop
- growler
- all of the above
ANSWER:-4
