Abstract: The invention relates to a shaft drive unit, in particular an electrical drive unit for driving a wheel shaft in vehicles; having an electrical machine comprising a rotor and a stator; having a transmission unit, comprising at least one input connected in a rotationally fixed manner to the rotor of the electrical machine, and at least one output connected in a rotationally fixed manner to the wheel shaft. The electrical machine, the input and the output of the transmission unit and the wheel shaft are arranged coaxially with respect to one another. The electrical machine has at least one associated converter unit and one associated braking resistor unit. The converter unit forms a physical unit with the electrical machine. The braking resistor unit is arranged in the immediate physical vicinity of the electrical machine and around the circumference of the input or output drive shaft of the electrical machine or of the wheel shaft.

Abstract: A method and apparatus for cooling a transverse flow synchronous machine is provided which uses a coolant that is entrained by the rotor rotation during operation of the synchronous machine and is sprayed into the intermediate spaces between the plurality of stepped elements along the surface of the outer stator thereby forming a coolant-air mixture.

Abstract: The invention relates to a stator module for an electric motor, especially an electric motor with transverse flux, comprising at least one stator unit that consists of at least one armature winding and which, when mounted, is associated with a rotor, whereby an interferric space is created in a radial direction in relation to the axis of symmetry of the electric motor.

Abstract: The invention relates to a rotor for an electric machine, specifically a transverse flow machine, comprising at least one support disk and at least one annular pole structure arranged on an end face of the support disk, coaxial to the rotor axis, and extending in axial direction. The pole structure comprises two adjacent rows, separated by an intermediate layer of magnetically and electrically nonconducting material (spacer ring), of the peripheral direction alternately magnetized magnet arrays with interposed collector or soft-iron elements. An end ring is coordinated with each pole structure. A plurality of magnet arrays features an inner and an outer magnet. The design of the collector or soft-iron elements adjoining a magnet array in the peripheral direction is such that they form in radial direction an inner stop and an outer stop for the magnet array.The invention is characterized in that an intermediate element is coordinated with a plurality of magnet arrays.
