Claims

[Scope of utility model registration request]

A permanent magnet field fixed to a rotating shaft, a first fixed magnetic pole having a magnetic pole piece of one pole, and a second fixed magnetic pole having a magnetic pole piece of the other pole are provided, and the first fixed magnetic pole and the second fixed magnetic pole are provided. In a magnet generator in which the magnetic pole pieces of the magnetic poles are arranged alternately so as to face the permanent magnet field, the fixed magnetic pole pieces are arranged at positions equally divided by the number of magnetic poles of the permanent magnet field plus or minus 2 or 3, A permanent magnet generator characterized in that void spaces corresponding to the adjusted number are provided at equal positions.
