  • Publication number: 20220149679
    Abstract: A method for producing a stator/housing arrangement for an electrical machine (1) having a stator (5) and a housing (2), wherein a housing part (3, 3a . . . 3c) of the housing (2) has at least one circumferential housing slot (4, 4a . . . 4c) and a stator laminated core (6, 6a . . . 6c) of the stator (5) has at least one circumferential stator slot (9, 9a . . . 9c). Here, the stator laminated core (6, 6a . . . 6c) is placed or pressed into the housing part (3, 3a . . . 3c) in a position in which the stator slot (9, 9a . . . 9c) and the housing slot (4, 4a . . . 4c) have a region of intersection (B). Afterwards, a potting compound (15) is introduced into the stator slot (9, 9a . . . 9c) and the housing slot (4, 4a . . . 4c).

  • Patent number: 10097057
    Abstract: An electric motor of a vehicle component, in particular a window opener drive or seat adjuster drive, includes a rotor, a stator with a three-phase stator winding having at least one coil per phase with first and second coil ends, and a connection element having a number of vias corresponding to the number of coil ends, the vias forming first and second contacting groups. The vias of the first contacting group are paired with a contact ring with contact points for electrically conductively connecting the first coil ends, in particular while forming a neutral point. The second coil ends are guided through the vias of the second contacting group, and a coil end portion or additional conductor element of the coil ends is azimuthally guided along the connection element and guided, preferably axially, out of the connection element while providing a three-phase winding connection at exposed positions.

  • Patent number: 8648503
    Abstract: The invention relates to an arrangement for acoustic decoupling of a stator of an electric motor having two substantially cylindrical decoupling rings disposed on both sides of the stator and concentric to a motor shaft, each fixed to a front side of the stator on one side and each fixed to a housing enclosing the stator on the other side, and comprising recesses on the circumferential surfaces thereof. The decoupling rings hold the stator in a centered position at a distance from the housing. The recesses allow targeted acoustic decoupling. The invention is particularly applicable for electric motors in steering systems for motor vehicles.

  • Publication number: 20120256513
    Abstract: A stator for a motor contains a number of stator sheets stacked in a star-shaped laminated core. The stator sheets contain stator sheets closed in the circumferential direction and have single teeth connected to one another by pole shoe webs and stator sheets open in the circumferential direction and have single teeth spaced apart from one another to form a gap. A bottom starting block is adjoined by a repeat block which has N identical repeat sequences. Each repeat sequence contains n directly consecutive open stator sheets with a gap on the pole shoe side and at least one closed stator sheet. The laminated core also has a terminating block and an intermediate block between the repeat block and the terminating block. The intermediate block contains a closed stator sheet and/or a gap on the pole shoe side created by m open stator sheets, where 1?m?n?1.
