Abstract
The disclosure relates to an electric motor having a base motor module and an electronic module. The electronic module is electrically and mechanically connected to the base motor module and comprises a printed circuit board and an electronics housing. The electronics housing forms two supporting surfaces, with which the printed circuit board can be brought into contact.
Claims20
An electric motor comprising:
- a base motor module, and
- an electronic module electrically and mechanically connected to the base motor module, the electronic module comprising:
- a printed circuit board, and
- an electronics housing forming:
- two supporting surfaces configured to contact the printed circuit board, and
- a mandrel extending through an opening in the printed circuit board,
- a plug configured:
- as a separate component from the electronics housing,
- to be inserted within an opening arranged on a peripheral side of the electronics housing, and
- to directly contact one of the two supporting surfaces of the electronics housing so that the one of the two supporting surfaces, via the plug, provides support for the printed circuit board when the printed circuit board is pressed into the electronics housing.

An electric motor configured for an internal combustion engine, the electric motor comprising:
- a base motor module having:
- a housing pot,
- a stator,
- a rotor mounted in the housing pot via a rolling bearing, and
- a flange plate fixed to the housing pot, the flange plate configured to attach the base motor module to a component outside of the electric motor so as to form a heat conduction path between the base motor module and the component, and
- an electronic module fixed to the base motor module via the flange plate, the electronic module comprising:
- an electronics housing having two supporting surfaces and a mandrel,
- a printed circuit board disposed within the electronics housing and supported by the two supporting surfaces, the printed circuit board having an opening configured to receive the mandrel, and
- a plug configured:
- as a separate component from the electronics housing,
- to be inserted within an opening arranged on a peripheral side of the electronics housing, and
- to directly contact one of the two supporting surfaces of the electronics housing so that the one of the two supporting surfaces, via the plug, provides support for the printed circuit board when the printed circuit board is pressed into the electronics housing, and
- the base motor module is inserted into the electronic module and electrical connections between the electronic module and the base motor module are produced by joining the modules together in an axial direction.
