Abstract: An electric motor for a fluid pump, in particular an oil pump, the electric motor comprising a housing in which a stator, a rotor, and a tapping plate are arranged, wherein the tapping plate comprises connecting contacts for the electrical connection to windings of the stator and connecting elements for connecting to an electronic control system and/or electronic positioning system, the tapping plate is formed or overmolded by a plastic material, and the stator is encased by an overmolding which forms a bearing seat for the rotor. The invention furthermore relates to a modular motor family for forming different, in particular differently powerful, fluid pumps comprising several brushless electric motors, wherein the individual electric motors differ from each other by different motor diameters and/or motor lengths and/or configuration variants. The invention furthermore relates to a production method for an electric motor.

Abstract: A permanent magnet rotor of an electric motor, consisting of a return body and a number of sintered permanent magnets distributed on the case of the return body at intervals, connected to a plastic mass filled with hard magnetic material. The objective of the present invention is to ensure that a generic permanent magnet rotor can be simply and economically produced, along with allowing a great degree of freedom regarding the design of the pole faces, wherein high rigidity and security of the mechanical connection between the permanent magnets and the return body are guaranteed.

Abstract: The invention relates to a drive system having at least one electrical direct drive and at least one bearing module, wherein the bearing module has a radial bearing and/or an axial bearing, and wherein the electrical direct drive and the bearing module have a cooling device.
