<P>PROBLEM TO BE SOLVED: To provide a synchronous rotary electric machine which can have torque larger than torque generated through mutual action between a rotating magnetic field of a stator and magnetic flux of permanent magnets of a rotor in synchronous operation. <P>SOLUTION: A synchronous rotary electric machine 11 includes a rotor 13 having a plurality of permanent magnets 19 arranged so that adjacent permanent magnets have alternately different magnetic poles, and a stator winding is a concentrated winding. The rotor 13 has bar conductors 20a arranged on inner-diameter sides of the permanent magnets 19 and at positions corresponding to gaps between permanent magnets 19 so as to always perform synchronous operation over the entire rotation area. The synchronous rotary electric machine 11 is characterized in that the number (q) of slots of each pole and each phase represented as q=Z<SB POS="POST">1</SB>/(2Z<SB POS="POST">2</SB>m) is a fractional slot smaller than 1/2, where Z<SB POS="POST">1</SB>is the number of slots, Z<SB POS="POST">2</SB>is the number of pole pairs, and (m) is the number of phases. <P>COPYRIGHT: (C)2012,JPO&INPIT |
