100% Pass
1. What is the function of laminations in motor field poles: Reduces eddẏ currents
2. Shifts the neutral plane with direction of rotation in generators: Armature Reaction
3. Armature Winding for high Current application: Lap windings
4. Armature Winding for high Voltage application: Wave windings
5. What is the current called that must flow through the field coil windings of a DC
generator to produce a magnetic field: Excitation
