Abstract
A plurality of permanent magnets are provided at a rotor at equal angular intervals. A plurality of magneto coils are provided at a stator at unequal angular intervals. The number of the plurality of magneto coils is not a multiple of three. The plurality of magneto coils include U-phase magneto coils, V-phase magneto coils and W-phase magneto coils. The U-phase magneto coils are arranged and connected such that phases of currents passing through the U-phase magneto coils are equal. The V-phase magneto coils are arranged and connected such that phases of currents passing through the V-phase magneto coils are equal. The W-phase magneto coils are arranged and connected such that phases of currents passing through the W-phase magneto coils are equal.
