Stator, radial flux twin-rotor machine and method for its manufacture

Abstract

The present invention relates to a stator for a radial flux twin-rotor machine, in particular for a wheel hub motor, comprising: a stator core; a winding placed in the stator core, which is self-supporting for torque support of the stator, wherein the winding projects beyond the stator core at at least one axial end; and a support device arranged axially offset from the stator core, which is in positive engagement with the winding at the at least one axial end for torque support, wherein the support device is designed at least partially as an electrical insulator and is arranged between the stator core and a winding head of the winding, the winding head having a heat sink separate from the support device. The present invention further relates to a radial flux twin-rotor machine, in particular for a wheel hub drive, with such a stator and to a method for its manufacture.
