| 发明名称 | Rotor for electric rotating machine | ||
| 摘要 | The rotor for an electric rotating machine includes a rotor core fixed to a rotating shaft and formed with at least one magnet accommodating hole, a magnet accommodated in the magnet accommodating hole, a resin portion filled in the magnet accommodating hole accommodating the magnet, a first end plate fixed to the rotating shaft at one axial side of the rotor core, and a second end plate fixed to the rotating shaft at the other axial side of the rotor core. The axial fixing force of the second end plate against the rotating shaft is smaller than that of the first end plate. At least a part of the resin portion is present in an axial area between the magnet accommodated in the magnet accommodating hole and the first end plate, and the magnet is in direct contact with the second end plate. | ||

| 主权项 | 1. A rotor for an electric rotating machine comprising: a rotor core fixed to a rotating shaft of the electric rotating machine and formed with at least one magnet accommodating hole; a magnet accommodated in the magnet accommodating hole; a resin portion filled in the magnet accommodating hole accommodating the magnet; a first end plate fixed to the rotating shaft at a first axial side of the rotor core; and a second end plate fixed to the rotating shaft at a second axial side axially opposite to the first axial side of the rotor core, an axial fixing force of the second end plate against the rotating shaft being smaller than an axial fixing force of the first end plate against the rotating shaft; wherein a part of the resin portion is present in an axial area between the magnet accommodated in the magnet accommodating hole and the first end plate, and the magnet is in direct contact with the second end plate. | ||
