| 20120235535 | ROTARY ELECTRIC MACHINE - There is provided a rotary electric machine. A stator is formed by laminating first steel plates and second steel plates, which are formed from an identical magnetic material and having an identical planar shape but different thickness dimensions. Hence, in contrast to a motor/generator (a comparative example) including a stator formed by laminating steel plates having an identical thickness dimension, with which a single resonance frequency is generated (such that a peak value is large), two resonance frequencies are generated, and therefore the peak value can be dispersed between the respective resonance frequencies (such that the peak value is small). | 09-20-2012 |
