ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2013/077109
Kind Code:
A1
Abstract:
Each flux barrier has a near-outer periphery section serving as a rotor outer peripheral-side plane and a near-inner periphery section serving as a rotor inner peripheral-side plane that extend from a connection section. At least the near-outer periphery section or the near-inner periphery section is continuously formed with an end of a magnet fixation section of a magnet hole in the inward direction of the magnet hole, and a bulge section, which bulges in the inward direction of the flux barrier, is provided at least on the near-outer periphery section or on the near-inner periphery section, whichever is continuously formed with the magnet fixation section. A narrow section, where the width of the flux barrier is narrower than the width of the flux barrier section positioned on the side closer to the connection section with respect to the bulge section, is formed by means of the bulge section.
