    摘要： A compressor includes a compressing section accommodated in a hermetic container and a motor section, coupled to the compressing section, for driving the compressing section. The motor section has a bored section on an end of the compressing section side and a motor having two rotor poles and including a rotor core in which permanent magnets are buried. The compressing section includes a bearing made of non-magnetic material and extending inside the bored section. This structure reduces both of loss torque due to magnetic attraction between an inner wall of the bored section and the bearing, and eddy-current-loss in the bearing, so that a highly efficient compressor is obtainable.

    摘要： A synchronous motor includes a stator, a rotor and permanent magnets. The rotor includes a rotor iron core and rotatable relative to the stator, a plurality of conductor bars accommodated within corresponding slots in the rotor iron core. The conductor bars have their opposite ends shortcircuited by respective shortcircuit rings to form a starter squirrel cage conductor. The rotor also have a plurality of magnet retaining slots defined therein at a location on an inner side of the conductor bars, in which hole permanent magnets are embedded.

    摘要： A synchronous motor includes a stator, a rotor and permanent magnets. The rotor includes a rotor iron core that is rotatable relative to the stator, and conductor bars accommodated within corresponding slots in the rotor iron core. The conductor bars have their opposite ends short-circuited by respective shortcircuit rings to form a starter cage conductor. The rotor also has a plurality of magnet retaining holes defined therein, in which permanent magnets are embedded. The conductor bar holes are positioned in an axial direction and inwardly from the magnet retaining holes. The conductor bars within the holes protrude outwardly from an axial end of the rotor iron core to form projections for securing an end plate to the end of the rotor iron core, the end plate comprising a non-magnetizable material.
