  • Patent number: 10475563
    Abstract: The actuator (10) comprises a body (12) formed by a single strip of ferromagnetic material, U-shaped and including a first and a second lateral branch (14, 16) facing each other and interconnected by an intermediate branch or portion (18). A first lateral branch (14) of the body (12) has a frustoconical formation (30) which extends in the region outside the body (12). A coil (22) is fixed in the body (12), and its axis (A-A) extends in a direction essentially orthogonal to the lateral branches (14, 16) of this body (12). A ferromagnetic core (28) is mounted so as to be translatable inside the coil (22), from a rest position to a working position, as an effect of the energizing of the coil (22). One end (32) of the core (28), facing towards the first branch (14) of said body (12), has a frustoconical shape essentially complementary to the internal shape (30b) of the formation (30). The frustoconical formation (30) of the first branch (14) of said body (12) is blind and has a planar distal bottom wall (30a).

  • Patent number: 10454335
    Abstract: A motor housing for an electric motor has a generally cylindrical housing shell (10), which, at one end (26), accommodates a first bearing and a housing cover module (12) such that the housing cover module (12) closes an opposing, open end of the housing shell (10), and serves as a second bearing. The cover module (12) is preferably of metal material and is integrally formed with a plurality of projecting tab and/or arm portions (14, 16, 18). Around the housing shell (10), several recesses or slots (20) are formed, flanked by deformable elements (30,32). By axially applying a tool (60), the deformable elements are deformed to secure the tabs (14, 16, 18) within the slots (20) and to thereby connect the shell (10) and the cover module (12) axially together. The resulting structure is highly resistant to vibrational decoupling, and can readily be obtained by high-speed automated production steps.
