PURPOSE:To enable to simultaneously generate two types of voltages having high and low frequencies by one generator by winding a low and high frequency armature windings on a stator core. CONSTITUTION:Exciting windings 5a, 5b are radially wound on a rotor core 6 so that salient poles become the same number of two groups 6Aa, 6Ba. The salient poles 6Aa of the portion A of the core 6 are all excited to N-poles by the windings 5a, 5b, and the salient poles 6Ba of the portion B are all excited to S-poles. A single phase AC output can be obtained from the armature winding 12 wound in the slot 2. When the poles 6Aa of the portion A are all excited to N-poles and the poles 6Ba of the portion B are all excited to S-poles, the bottom of the recess 6Ab between the poles 6Aa is slightly excited to the N-pole, and the bottom of the recess 6Bb between the poles 6Ba is slightly excited to the S-poles. High frequency 3-phase outputs are obtained from 3-phase armature windings 4 wound in the slots 2. |
