Abstract
An electric actuator comprises a motor and a plate, wherein the motor has an electric contact in electrical contact with the plate. An intermediate shaft is in contact with the plate. A controller is fixed to an upper part of the actuator. The controller has an electrical output electrically communicating with the electric contact of the motor through the intermediate shaft and the plate.
Claims21
An electric actuator, comprising:
- a casing having an upper part and a lower part, delimiting an inner volume between them;
- a motor received in a motor housing of the lower part, the motor housing communicating with the inner volume by an opening;
- a plate made from an electrically conductive material arranged on the opening, the plate having a drive shaft orifice in which an upper end of the motor is engaged, a drive shaft emerging from the upper end, the drive shaft supporting a drive pinion, the motor having an electric contact in electrical contact with the plate, wherein an end part of the drive shaft supporting the drive pinion is located on a side of the plate opposite to the motor housing;
- an intermediate shaft made from an electrically conductive material and supporting a toothed wheel meshing with the drive pinion, the intermediate shaft being engaged in an intermediate orifice of the plate and being in contact with the plate;
- and
- a controller fixed to the upper part, the controller having an electrical output electrically communicating with the electric contact of the motor through the intermediate shaft and the plate.

- a casing having an upper part and a lower part, delimiting an inner volume between them;
- a motor received in a motor housing of the lower part, the motor housing communicating with the inner volume by an opening;
- a plate made from an electrically conductive material arranged on the opening, the plate having a drive shaft orifice in which an upper end of the motor is engaged, a drive shaft emerging from the upper end, the drive shaft supporting a drive pinion, the motor having an electric contact in electrical contact with the plate, and wherein the plate includes at least one securing tab urging the upper end of the motor against a determined segment of a peripheral edge of the drive shaft orifice, thus defining a position of the drive shaft relative to the plate an intermediate shaft made from an electrically conductive material and supporting a toothed wheel meshing with the drive pinion, the intermediate shaft being engaged in an intermediate orifice of the plate and being in contact with the plate;
- and
- a controller fixed to the upper part, the controller having an electrical output electrically communicating with the electric contact of the motor through the intermediate shaft and the plate.
