摘要： An apparatus for manufacturing an electric motor having a laminated core structure formed by a plurality of core plates made of rolled material of electromagnetic sheet steel. The core plates are manufactured by punching rolled electromagnetic sheet steel in a die set. The rolled electromagnetic sheet steel is displaced angularly relative to the die set. The core plates have rolling directions of the electromagnetic sheet steel angularly displaced by a machine angle determined in accordance with the number of slots or poles provided in the laminated core structure so that a phase difference of cogging torques produced by magnetic anisotropy of the core plates is substantially 180°.

摘要： A cooling jacket for an electric motor and a motor unit with a cooling jacket mounted on an electric motor having simple structure and capable of being manufactured with reduced number of processes. A cooling pipe made of copper and the like is bent, and held by plate members and lid members, and resin having high heat-conductivity is filled in between to form a series of segments of the cooling jacket. Adjacent ones of the segments are connected with each other by connecting members to form the cooling jacket. The plate members are formed to conform with a shape of the electric motor. The series of segments are mounted on an outer surface of the electric motor and gaps between the adjacent segments are adjusted to bring the plate members into close contact with the outer surface of the electric motor. Since the cooling jacket is mounted on the electric motor after finishing the manufacturing of the electric motor, the electric motor is easily provided with cooling structure with reduced number of manufacturing processes.

摘要： A motor capable of reducing cogging torque depending on teeth of a stator, and a motor manufacturing apparatus for manufacturing this motor. The angles of rolling directions of cores stacked are set so that the phase difference between the phases of cogging torques produced on the cores is 180° so that the cogging torques produced on the cores cancel each other to reduce the total cogging torque in the motor. The motor comprises a laminated core formed by stacking a plurality of cores made from a rolled electromagnetic sheet steel. The cores forming the laminated core have rolling directions different from each other by a specified machine angle determined depending on the number of slots and/or the number of poles, where the specified machine angle is an angle which produces a phase difference of 180° between the phases of cogging torques produced due to magnetic anisotropy of the cores and the arrangement of teeth depending on the number of slots and/or poles of the motor.

摘要： Flat rolled magnetic steel sheets and strip or a die is turned in the press forming process. Rotor cores are stacked with turning through an angle which is an odd number multiple of about (360°/(number of slots in the motor×natural number n×2) and stator cores are stacked with turning through an angle which is an odd number multiple of (360°/(number of poles in the motor×natural number n×2)). Stacking with turning through an angle which is an odd number multiple converts the phases of cogging torques into mutually opposite phases and cancels and reduces the cogging torque caused by magnetic anisotropy.

摘要： A synchronous electric motor including a rotor having a rotation axis, and a stator surrounding the rotor through a gap. The rotor includes a rotor core having an outer circumferential surface extending about the rotation axis and a plurality of permanent magnets attached to the rotor core to form plural poles along the outer circumferential surface of the rotor core. The outer circumferential surface of the rotor core is provided, at each pole, with a contour deviating from a circular arc and bulging out in a radial outward direction, as seen in a cross-section perpendicular to the rotation axis. The permanent magnets include a plurality of magnet sets individually assigned to the plural poles, each set including two or more permanent magnets. The contour of the outer circumferential surface of the rotor core, at each pole, has at least partially a shape represented by a hyperbolic cosine function or a secant function.
