Document Type and Number:
Japanese Patent JP7367413
Kind Code:
B2
Abstract:
A rotating electrical machine equipped with a magnet unit and a magnetic body. The magnet unit is also equipped with magnet covers wrapped about armature-facing peripheral surfaces of the magnets. Each of the magnets has recesses formed in portions of the armature-facing peripheral surface which are located close to q-axes each of which lies at a boundary between magnetic poles. Each of the magnet covers is recessed in the radial direction in accordance with the shape of the magnet recesses. If the armature-facing peripheral surface of the magnets is between a circumferentially adjacent two of the magnet recesses is defined as a main magnetic pole surface, and an angle representing a circumferential range occupied by the main magnetic pole surface is defined as a main magnetic pole angle θa, the main magnetic pole angle θa is selected to be 2π/5<θa<2π/3.
