摘要： In a method for firmly connecting a shaft to a rotor-housing part, the rotor-housing part is provided having a bearing flange and the shaft is provided having a recess, extending in the circumferential direction of the shaft, on an outer circumference of the shaft. The shaft is inserted into the bearing flange such that the recess and the bearing flange overlap one another. Material of the bearing flange is introduced into the recess. With the connection, created in this way, between the shaft and bearing flange, a high press-out force is achieved.

摘要： In a motor device, since the bearing support member mounted to the housing and supporting, from the axial direction, the another axial side of the ball bearing (outer race) includes the annular support part (annular flat surface) which supports, from the axial direction, the entire circumference of the another axial side of the ball bearing (outer race), tilting of the ball bearing with respect to the housing can be suppressed in the case where a lateral force acts on the rotating shaft. Therefore, it is possible to improve the fixing strength of the ball bearing to the housing, and thus suppress rattling of the speed reduction mechanism.

摘要： A drive includes an electric motor disposed in a housing and driving a motor shaft, a Hall effect sensor adjacent to the motor, a power and control assembly, and a pinion gear driven by the motor shaft. A planetary gear reduction assembly is driven by the pinion gear, and an output axle has an axis of rotation that is offset from and parallel to the motor shaft axis of rotation. The reduction drive is substantially bilaterally symmetrical about a plane passing through the motor shaft axis of rotation and the output axle axis of rotation. The power and control assembly comprises a control board oriented perpendicular to a power board and includes a heat dissipation apparatus that applies multi-point, localized, indirect pressure to a plurality of field effect transistors mounted on the power board.

摘要： A canned electric motor for a fluid pump. The canned electric motor includes a static motor frame, a rotor shaft, a rotatable motor rotor which is co-rotatably connected with the rotor shaft, a static motor stator having a stator body which is directly fixed to the static motor frame, and a separating can which fluidically separates the static motor stator from the rotatable motor rotor. The separating can has a first axial support which protrudes radially from an outside of the separating can. The separating can is supported in a first axial direction by the stator body via the first axial support and in a second axial direction by the static motor frame. The first axial direction is opposite to the second axial direction.

摘要： An electric assembly includes: a box assembly, a motor, and a transmission. A mounting plate is disposed in the box assembly and divides a space within the box assembly into a motor holding cavity and a transmission holding cavity arranged along an axial direction of a motor shaft. The mounting plate has a shaft via-hole making the motor holding cavity and the transmission holding cavity be in communication. The motor is disposed in the motor holding cavity. The transmission is disposed in the transmission holding cavity. The motor is power-coupled to the transmission. At least one of a surface of the mounting plate facing the motor and a surface of the mounting plate facing the transmission is provided with ribs including strip-shaped ribs extending along a radial direction of the motor. Heights of the strip-shaped ribs decrease from a center portion of the mounting plate to a periphery portion of the mounting plate.
