Abstract
An electric motor (2) has a base motor module (3) and an electronic module (18) which is electrically and mechanically connected to the base motor module (3) and comprises an electronics housing (12). The base motor module (3) comprises a flange plate (8) which forms an interference fit with the electronics housing (12). The flange plate (8) may have an opening (36) with a circumferential collar (39) which engages in a fastening passage (35) of the electronics housing (12) and forms the interference fit with the electronics housing (12).
Claims15
An electric motor comprising:
- a base motor module;
- and
- an electronic module which is electrically and mechanically connected to the base motor module and which comprises an electronics housing, the base motor module having a flange plate which forms an interference fit with the electronics housing,
- wherein the flange plate has openings passing through the flange plate, each opening being surrounded by a respective circumferential collar, the circumferential collars each engaging in a respective fastening passage of the electronics housing and forming the interference fit with the electronics housing.
A method of constructing an electric motor comprising:
- providing a base motor module including a rotor, a stator and a base housing enclosing the rotor and the stator, the base motor module further including a flange plate contacting the base housing;
- providing an electronic module comprising an electronics housing and a control board within the electronics housing;
- connecting the base motor module and electronic module together, the connecting including pressing the flange plate onto the electronics housing to form an interference fit between the flange plate and the electronics housing;
- constructing the electronic module prior to the connecting by joining together a plurality of plug modules including a plug connector, the electronics housing and the control board.
