Patent ID: 7876063

Claim:
An axial gap type motor/generator comprising: a stator including a plurality of stator iron cores with a coil disposed on each of the stator iron cores; a rotor facing the stator, with the rotor including a plurality of magnetic poles; and an alternating current control device configured to execute alternating current control of a single phase or multiple phase alternating current flowing in the coils, the alternating current control device including a superpositioning control section configured to produce the alternating current by superpositioning a plurality of frequency components including a first order fundamental wave component and a plurality of higher harmonic wave components that have frequencies equal to integer multiples of a frequency of the fundamental wave components and are of orders that are equal to values of the integer multiples; and a frequency component control section configured to control a relationship among the frequency components such that two pairs of the frequency components whose orders differ by two are aligned with respect to each other.
