ROTOR OF PERMANENT MAGNET TYPE SYNCHRONOUS ROTATING ELECTRIC MACHINE, THE PERMANENT MAGNET TYPE SYNCHRONOUS ROTATING ELECTRIC MACHINE, AND VEHICLE, ELEVATOR, FLUID MACHINE OR PROCESSING MACHINE USING THE PERMANENT MAGNET TYPE SYNCHRONOUS ROTATING ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a rotor of a permanent magnet type rotating electric machine capable of increasing output torque.;SOLUTION: The rotor includes a rotor core 2 having a rotating axis O; and a first permanent magnet 31 and a second permanent magnet 32 which are arranged so as to trace each side of letter V mutually having the rotating axis side as an apex in a cross section of the rotor core perpendicular to the rotating axis and form one pole mutually. In the cross section of the rotor core, the first and second permanent magnets are arranged so as to interpose a straight line connecting a point of the rotating axis to the apex of the letter V mutually, an angle 1 formed by the straight line and the first permanent magnet is smaller than an angle 2 formed by the straight line and the second permanent magnet, and a width 31w of the first permanent magnet in a direction parallel to one side of the letter V traced by the first permanent magnet is smaller than a width 32w of the second permanent magnet in a direction parallel to the another side of the letter V traced by the second permanent magnet.;COPYRIGHT: (C)2011,JPO&INPIT
