Abstract (in Japanese) (See Japanese page) 
(in English) The relationship between the experimental revolution speed characteristics and the sound field in the air gaps analyzed by FEM is investigated. The standing wave sound fields with a reverse phase are generated in the two air gaps by the single drive stator. The traveling wave sound fields are formed in the two air gaps as the superposition of the standing wave sound fields generated by the two stators whose temporal phase and spatial position differ. The traveling direction of the calculated sound fields has coincided with the rotation direction of rotor which has been observed in the experiments.
