Mode Of Operation Flashcards
1
Q
Describe what happens when field is rotated
A
Flux lines cross winding = voltage induced and current flow
2
Q
What happens when the current carrying winding produces a magnetic field
A
Builds up on poles, repel and attract, rotor and rotating field spin in same direction
3
Q
Why is rotational speed of rotor always lower than the rotational speed of field
A
Flux lines wouldn’t be cut
Current and voltage = 0
No torque
