摘要： A motor has a stator having a plurality of teeth for receiving windings, a yoke connected to each tooth, and a rotor having permanent magnets facing the stator. An inner wall surface of each tooth faces the rotor with an air-gap therebetween. Each tooth is separated from an adjacent tooth by a slot-open-section extending between a tailing end of the tooth and a leading end of the adjacent tooth. The inner wall surface of each tooth has an arc extending from a center of the slot-open-section toward the tailing end. The air-gap at the tailing end of each tooth is greater than the air-gap at the leading end of each tooth. The inner wall surface of each tooth includes a straight-line tailing section extending from the center of the slot-open-section toward the leading end. The straight-line tailing section extends tangentially from the arc.

摘要： In a method of magnetizing a material of a permanent magnet portion provided in a rotor for a permanent-magnet motor, the material of the permanent magnet portion is embedded inside the rotor body, while the permanent magnet material has anisotropy in a direction penetrating the permanent magnet portion in section, and then the rotor is incorporated in a magnetizing unit and held in a rotatable manner, and the permanent magnet material is magnetized by flowing a magnetizing current through windings under the condition that the rotor is rotatably held in the magnetizing unit. Thus, the permanent magnet material is completely magnetized in a normalized direction, and even if the rotor is shifted from the normalized position, the rotor is retained back to the normalized position by a magnetic torque.

摘要： A rotor of a motor includes a plurality of sets of permanent magnets 8a, 8b embedded in the rotor. Each includes a permanent magnet at an inner side and another permanent magnet at an outer side with a distance between them. Each permanent magnet 8a, 8b is formed like an arch projecting towards the center of the rotor. Magnetic flux flows easily through an interval between the permanent magnets at inner and outer sides, and the inductance in a q-axis is enlarged. Then, the reluctance torque is generated in addition to the magnet torque, and the motor has a high torque and a high output power.

The prism portion has a length measured in a first direction perpendicular to the lamination direction and a height measured in a second direction perpendicular to the lamination direction and the first direction. The length of the prism portion gradually increases along the lamination direction in at least part of the prism portion. The first rectangular solid portion is adjacent to the prism portion in the second direction. The first rectangular solid portion has a uniform length measured along the first direction. Preferably, a plurality of the armature cores are mounted on a yoke and have armature windings wound to form an armature of a rotary electric machine of a compressor.
