Problems solved by technology

[0003] Such motors usually have a deep-drawn motor housing. When designing the interface between the motor housing and the internal parts of the motor, it must be taken into account that internal forces acting on the entire system may additionally be superimposed on external forces, which may be caused, for example, by the entire system occurs due to the strong acceleration of

Embodiment Construction

[0020] figure 1 A deep-drawn motor housing 1 of the electric motor is shown. The motor housing 1 is a pot-shaped body with a substantially cylindrical outer surface 2, a closed, continuous base 3, and an opening opposite the base 3, the opening being circumferentially surrounded by a flange 5 having a substantially cylindrical shape. Rectangular base with four flange corners 6, of which only three flange corners 6 are shown, these flange corners 6 are evenly distributed in the circumferential direction, and each flange corner 6 is provided separately There are through holes 7 for screw-on fixing points 8 . In the area of ​​the flange corners 6 , the flange 5 also has projections 9 and 10 extending downward in the direction of the base 3 . Each flange corner 6 corresponds to two projections 9 and 10 , and the two projections The symmetry axis 100 is arranged in mirror symmetry, and the symmetry axis 100 is respectively connected with the central axis or longitudinal axis 200 ...

Abstract

The invention relates to an electric motor having a deep-drawn motor housing having a flange (5) adjoining an opening (4), the cross-section of which is substantially polygonal, each flange corner (6) being provided with a threaded fastening point (8), each flange corner (6) having in each case two projections (9, 10), in each case, the two projections form a curved edge (14) of the motor housing between the screw fastening point (8) and the opening (4).

Description

technical field [0001] The present invention relates to a motor. Background technique [0002] An electric motor, known as an inner rotor motor, has a rotor that contains the motor shaft and is rotatably mounted within a housing, the rotor is provided with permanent magnets, and a stator is arranged around the motor, the iron core of which carries a plurality of windings. When properly controlled, the windings generate the magnetic field that drives the rotation of the rotor, the windings are usually of a three-phase design, and accordingly three electrical connections are provided through which the windings can be connected to a control unit (ECU). The ends of the windings are contacted by bus bars, which can be encapsulated in bus bar units. [0003] This type of motor usually has a deep-drawn motor housing. When designing the interface between the motor housing and the internal components of the motor, it must be considered that internal forces acting on the entire syste...
