摘要： A rotor (10) includes a plurality of permanent magnets (14) disposed around a shaft (12) at generally equal intervals, and a plurality of laminated core members (16) disposed between the permanent magnets (14) so as to form magnetic poles. The laminated core members (16) are formed by stacking a plurality of core-laminations (26) made of magnetic materials and an integral core-lamination, and joining them to each other. The integral core-lamination includes a plurality of core-lamination sections each having a shape the same as that of the core-lamination (26), and connecting portions (46) for connecting adjacent core-lamination sections with each other. When the large number of core-laminations (26) and the integral core-lamination are integrally joined by a press-fitting process, the laminated core members (16) are connected with each other in such a relative arrangement of a finished assembly that a space for locating the permanent magnet (14) is defined between the adjacent laminated core members (16), and thus an integral laminated rotor core (48) is formed.

摘要： A rotor (10) includes a plurality of permanent magnets (14) disposed substantially equidistantly round a shaft (12) and a plurality of laminated core members (16) each being disposed between the permanent magnets (14) and forming a magnetic pole.

摘要： An electric motor that does not provide new terminals for carrying out conductive caulking, and further, facilitates the work of using a conductive caulking machine. An electric motor coil connecting structure that connects conductors connected to a power input member and lead terminals of coils by conductive caulking and connects the power input member and the lead terminals of the coil electrically. One end of each of the conductors is formed into a terminal-shaped portion in which the lead terminals of the coil can be fitted and temporarily retained. The lead terminals of the coil are fitted in the terminal-shaped portion of the conductors and temporarily retained, and connected by conductive caulking.

摘要： A permanent magnetic synchronous electrical motor, in which the waveform of the induced voltage is more similar to the sine curve than the prior art, so as to reduce the torque ripple. The outer shape of a rotor core of the electrical motor is specified by using the reciprocal of the cosine function. In the invention, the range of an electrical angle of the rotor, in which the reciprocal of the cosine function is applied to the outer shape of the rotor core, is equal to or more than 160 degrees.
