Abstract: In a method for manufacturing an interior permanent magnet rotor unit, a radial magnetizing part including high magnetic permeability portions and low magnetic permeability portions face a core, and a magnetic field of axial magnetizing parts is applied to the radial magnetizing part in an axial direction of the radial magnetizing part. This causes the magnetic field to enter the core via the radial magnetizing part and cross magnet materials filling insertion holes of the core.

Abstract: At least part of each bridge portion is heated and molten to form a keyhole, and a nonmagnetic element is disposed around the keyhole. Thus, even when the width of the bridge portion in the radial direction is increased, the bridge portion is demagnetized. Therefore, leakage flux in the bridge portion is reduced, and the output power of a motor is increased. Moreover, by increasing the width of the bridge portion in the radial direction, the strength of the bridge portion is increased, and breakage of the bridge portion due to a centrifugal force at high-speed rotation of a rotor is prevented.
Abstract translation: 每个桥接部分的至少一部分被加热并熔融以形成锁孔，并且在锁孔周围设置非磁性元件。 因此，即使在桥接部的宽度方向上的宽度增大的情况下，桥接部也被退磁。 因此，桥接部的漏磁通减少，电动机的输出功率增大。 此外，通过增加桥接部分在径向方向上的宽度，桥接部分的强度增加，并且防止了由于转子高速旋转时的离心力引起的桥接部分的断裂。

Abstract: An orientation magnetization device includes plural orientation magnetization yokes and plural orientation magnetization magnets, and molds field magnets while a rotor core is disposed in a magnetic circuit that is formed by assembling the orientation magnetization yokes and the orientation magnetization magnets into an annular shape. When the rotor core is disposed in the magnetic circuit, protruding portions are disposed at portions of the respective orientation magnetization yokes facing the rotor core. Auxiliary magnets are disposed in gaps between the respective orientation magnetization magnets and the rotor core, on opposite sides of each protruding portion in a circumferential direction of the orientation magnetization device. Each protruding portion and each auxiliary magnet extend in an axial direction of the orientation magnetization device, and are skewed with respect to the axial direction of the orientation magnetization device.

Abstract: A radial magnetizing part including permanent magnets is disposed so as to face a rotor unit in a radial direction of the rotor unit. Axial magnetizing parts are disposed on both end faces in an axial direction of the rotor unit. The axial magnetizing parts include low magnetic permeability portions and high magnetic permeability portions. The low magnetic permeability portions are disposed so as to face magnet materials. Magnetic flux from the N pole of the permanent magnet of the radial magnetizing part enters a core in the radial direction, crosses the magnet material, and returns to the S pole of the permanent magnet. The magnetic flux from the N pole of the permanent magnet of the radial magnetizing part also enters the core through the high magnetic permeability portions of the axial magnetizing parts, crosses the magnet material, and returns to the S pole of the permanent magnet.
