    摘要: The invention relates to an electric machine, in particular to a generator for supplying the electrical system of a motor vehicle, comprising a laminated rotor (20) with an energiser winding (29), which provides the energisation for the machine preferably in conjunction with permanent magnets (24, 25) arranged on the rotor periphery. According to the invention, the rotor laminate bundle (21) is made up of at least two part bundles (21a, b) in the axial direction with grooves (40) running into each other and with poles offset relative to each other (32 to 38). A machine with reduced detent torque is thus obtained with grooves (40) aligned parallel to the axis, in which the energiser windings (29) can be placed with a high filling factor and without production difficulties and without the risk of damaging the winding insulation.

In order to improve the design options of the stator of the machine, its multiphase winding is developed as a fractional-slot winding, whereby, in particular with respect to the selection of the number of slots, many additional options are created, by which both the production is made clearly simpler and less costly and, at the same time, the electrical properties are able to be improved.

    摘要: The present invention relates to an electrical machine having a rotor, a stator, a rotating-field production device, and a pole-field production device. The rotor can rotate about a rotation axis which passes through opposed upper and lower portions of the rotor. The rotating-field production produces an essentially radial magnetic field which rotates about the rotation axis of the rotor. The pole-field production device produces a magnetic field of opposite polarity to the rotor on the upper and lower portions. In order to reduce the size of the electrical machine without reducing the power, the pole-field production device has at least one magnet.
