摘要： A mold used in a manufacturing process of a rotor of an electric motor, the rotor including a rotor core with a plurality of magnet-retaining apertures and a plurality of permanent magnets individually retained in the magnet-retaining apertures of the rotor core, for pouring a resinous material into gaps defined between the magnet-retaining apertures and the permanent magnets. The mold includes a cavity for accommodating the rotor core at a predetermined position, with the rotor core receiving the permanent magnets individually in the magnet-retaining apertures; and a deformation inhibiting surface provided in the cavity and coming into at least local contact with an outer circumferential surface of the rotor core, during a period when the resinous material is poured into the gaps, to inhibit the bulging deformation of the outer circumferential surface.

摘要： A rotor of an electric motor, including a rotor core having a plurality of magnet-retaining apertures, a plurality of permanent magnets individually received and retained in the magnet-retaining apertures of the rotor core, and a resinous filler filling a gap defined between each magnet-retaining aperture and each permanent magnet and fixing the permanent magnets to the magnet-retaining apertures. The rotor also includes an engaging projection provided in the rotor core, the engaging projection tightly engaged with each of the permanent magnets received in the magnet-retaining apertures and temporarily holding each permanent magnet at a predetermined position in a corresponding magnet-retaining aperture, in an unfinished state of the rotor where the resinous filler is not arranged in the gap.

摘要： A housing of an electric motor is fitted with an oil seal having the function of sealing an output shaft (rotary shaft) of the motor. The housing is provided with a hole for motor airtightness testing communicating with an internal space of the motor. A local or annular projection configured to close the hole for motor airtightness testing, thereby maintaining the airtightness of the internal space of the electric motor, is disposed on that surface of the oil seal which faces the housing.
摘要翻译：电动机的壳体配有具有密封电动机的输出轴（旋转轴）功能的油封。壳体设置有用于与电动机的内部空间通信的电动机气密性测试的孔。在面向壳体的油封的表面上设置有用于闭合用于电动机气密性测试的孔，从而保持电动机的内部空间的气密性的局部或环形突起。
