In a commercial synchronous generator, why is the armature winding generally kept stationary on the stator?
- 1The rotor cannot mechanically support any winding under any circumstances.
- 2A stationary armature significantly reduces the main magnetic field requirement.
- 3It simplifies high-voltage insulation and allows direct connection without slip rings.✓
- 4The generator produces substantially more electrical power if windings are stationary.
Correct answer
It simplifies high-voltage insulation and allows direct connection without slip rings.
