摘要

PROBLEM TO BE SOLVED: To provide a magnetic steel sheet formed body, a magnetic steel sheet laminate, a rotor for permanent-magnet synchronous rotating electrical machines equipped therewith, a permanent-magnet synchronous rotating electrical machine, and a vehicle, an elevator, a fluid machine, and a processing machine using the rotating electrical machine, wherein saturation of q-axis flux is suppressed in a core portion formed in between the upper end faces of two magnet holes arranged in a V shape and the peripheral portion of a rotor to utilize reluctance torque and to enhance magnet torque, large torque is provided at start and in abrupt load fluctuations, and high efficiency is obtained.;SOLUTION: The two magnet holes 2, 3 for inserting two permanent magnets 6, 7 for one pole are provided along a V shape within a range between radial pole pitch lines OP, provided with a predetermined pole pitch angle in a rotor core 11. One of these magnet holes 2 is shifted in the direction of its moving away from the center line OC of the pole pitch lines OP, and the other is shifted in the direction of its coming close to the center line OC of the pole pitch lines OP.;COPYRIGHT: (C)2009,JPO&INPIT
