Question

Advantages of inside out construction of ac generator

Answer 1

Answer:

1. At high voltages, it easier to insulate stationary armature winding, which may be as high as 30 kV or more.

2. The high voltage output can be directly taken out from the stationary armature. Whereas, for a rotary armature, there will be large brush contact drop at higher voltages, also the sparking at the brush surface will occur.

4. Field exciter winding is placed in rotor, and the low dc voltage can be transferred safely.

5. The armature winding can be braced well, so as to prevent deformation caused by the high centrifugal force.
