摘要： An electric motor of a motor vehicle, in particular a steering motor, includes a housing having a motor compartment and an electronics compartment. The motor compartment and the electronics compartment are separated by a housing wall that has a plurality of openings. A stator is situated in the motor compartment and an electronics system is situated in the electronics compartment. The stator and the electronics system electrically contact one another through phase connections which project through the openings. A separating element is situated between the stator and the electronics system. The separating element at least partially covers the openings and the housing wall.

摘要： A power supplying-side terminal (38) has a power supplying-side hanging portion (38H) extending toward a surface of the circuit board (31), a power supplying-side extending portion (38E) bent from the power supplying-side hanging portion (38H) and extending outwards along the surface of the circuit board (31) and a power supplying-side standing portion (38S) bent from the power supplying-side extending portion (38E) and extending in a direction away from circuit board (31). A power receiving-side terminal (39) has a power receiving-side extending portion (39E) extending outwards along the surface of the circuit board (31) and a power receiving-side standing portion (39S) bent from the power receiving-side extending portion (39E) and extending in the direction away from circuit board (31). The power supplying-side standing portion (38S) and the power receiving-side standing portion (39S) overlap each other, and connected to each other so as to have electrical continuity.

摘要： An electric actuator includes a motor which has a rotor having a motor shaft extending along a central axis and a stator facing the rotor in a radial direction, a motor case for housing the motor, and a deceleration mechanism coupled to one axial side of the motor shaft. The motor case has a case cylinder portion, a lid for covering, and a plurality of screws. The case cylinder portion has a plurality of screw fixing portions. The lid has a top plate portion, an outer cylinder portion which surrounds the case cylinder portion from a radial outer side, an annular groove portion, and a seal member which seals the opening portion of the case cylinder portion. In the lid, an axial thickness of a region which overlaps the annular groove portion as viewed in the axial direction is larger than an axial thickness of the top plate portion.
