Across
- 3. An assembly of insulated conducting segments connected to the rotating armature winding.
- 6. Change-over switching in a periodic and automatic manner without interruption of the electric current.
- 7. A distributed winding in which the individual coils of each phase group per pole are concentric and have different coil spans.
- 8. Set of series connected turns.
- 9. The rotating speed at which resonance occurs.
- 11. A material which contains movable electrical charges.
Down
- 1. The factor by which short pitching a coil reduces the back e.m.f.
- 2. The amount of electrical energy stored for a given electric potential.
- 4. Magnetic interaction between stator and rotor resulting in undesired machine operation such as jerkiness.
- 5. The number of tooth pitches which separate the slots in which the two sides of a coil are placed.
- 10. Loss The electrical losses in a machine caused by the magnetisation of the core iron.
