Abstract
An electric machine may include a housing having a front end and a back end where the front end is the primary mechanical coupling end. The electric machine may include a stator and a rotor arranged within the housing and a shaft connected to the rotor. The shaft may extend out of the front end of the housing and the shaft may be configured to be rotationally driven by the rotor or to rotationally drive the rotor. The electric machine may also include an electronic controller configured to control operations of the rotor and stator and the electronic controller may be mounted on the front end of the housing.
Claims20
An electric machine, comprising:
- a housing having a front end bell and a back end bell,
- a stator and a rotor arranged within the housing;
- a shaft connected to the rotor and rotationally coupled to the front end bell and the back end bell and the shaft having an extended length forward of the front end bell, the shaft configured to be rotationally driven by the rotor or to rotationally drive the rotor;
- an electronic controller configured to control operations of the stator and the rotor;
- and
- a controller housing for components of the electric controller forward of the front end bell, the controller housing having an annular structure forming an annular cavity for the controller components concentric with the extended length of the rotating shaft and the annular structure having an inner wall and an outer wall radially spaced from the inner wall and the inner and outer walls configured to form an enclosure seperating the annular cavity from the extended lenght of the rotating shaft to provide a protective barrier between the controller components and the rotating shaft.
An electric machine, comprising:
- a front end bell and a back end bell;
- a stator and a rotor arranged between the front end bell and the back end bell;
- a shaft connected to the rotor and rationally coupled to the front end bell and the back end bell and the shaft having an extended lenghth forward of the front end bell, the shaft configured to be rotationally driven by the rotor or to rotationally drive the rotor;
- an electronic controller including controller components configured to control operations of the stator and rotor;
- and
- a controller housing having an annular structure forward of the front end bell and concentric with the extended length of the shaft and means for integrating the annular structure with the front end bell to form an annular cavity for housing the controller components and an annular enclosure seperating the controller components from the rotating shaft.
An electric machine, comprising:
- a front end bell and a rear end bell;
- a stator and a rotor;
- a shaft connected to the rotor and rotationally coupled to the front end bell and the back end bell and having an extended length forward of the front end bell, the shaft configured to be rotationally driven by the rotor or to rotationally drive the rotor;
- electronic controller components configured to control operations of the stator and the rotor;
- and
- a controller housing for the controller components having an annular structure integrated with the front end concentric with the extended length of the rotating shaft and the annular structure configured to form an annular cavity for the controller components and an enclosure seperating the annular cavity from a power take-off cavity coextending along the extending length of the shaft between the front end bell and a front end of the machine.
