The invention relates to a stator having a multi-phase wave winding made of hairpin conductor elements (). Each phase consists of two parallel or serially connected branches (). Each branch has a first () and a second () winding portion, which are connected to each other in series. The slot position of the two limbs () of each hairpin conductor element alternates by +&#x2212;1. The first winding portion () extends clockwise along the stator circumference; the second winding portion () extends counterclockwise and is connected to the first winding portion via a reverse-connector conductor element (). Both limbs of the reverse-connector conductor element () of the first winding branch () are located in the uppermost slot position; the limbs of the reverse-connector conductor element () of the second winding branch () are located in the lowermost slot position.

Stator for an electric machine

The invention relates to an electric motor, in particular for a motor vehicle, comprising a housing (), a shaft () having an axle (), a stator and a rotor, at least one channel () for conducting a coolant for cooling the electric motor (), wherein the geometry of the alignment of at least one section () of the at least one channel () is designed such that the coolant flows in the direction of the axle () of the shaft () through the at least one channel (), having a deviation of less than 40&#xb0;.

Electrical machine comprising cooling channels

A drive for an hybrid vehicle, having an electric machine situated in a housing and having a clutch that is provided with a release mechanism. The release mechanism is connected to a housing-mounted component, that is locked against rotation, via at least one damping element, the damping element absorbing multi-dimensional motions.

A method for manufacturing an electric machine, made up of a housing, a stator accommodated in the housing, which is formed from a stator body and stator windings, a rotor, which is supported in the housing so as to be rotatable about a rotor axis, and a bearing support fastened on the housing, includes a housing foam part manufactured from at least three individual foam parts and a housing cast blank manufactured using the housing foam part in accordance with a lost foam casting method. Individual foam parts are made up of a center disk having an essentially hollow-cylindrical design and forming an intermediate piece of a housing foam part, an annular disk having an essentially hollow-cylindrical design and forming another intermediate piece of the housing foam part, and a bearing support disk having an essentially cup-shaped design and forming an end of the housing foam part.

A magnetic field sensor, in particular an rpm sensor and/or rotational direction sensor and/or position sensor for the drive train of a motor vehicle, has a sensor array, with a sensor element that responds to a magnetic field, and optionally with a permanent magnet, the latter being sheathed with plastic jointly with the sensor array and parts of terminal conductor tracks, and the conductor tracks are embodied in one piece with a fixing element for the permanent magnet and the sensor array as a stamped grid, wherein stamped grid is shaped as a three-dimensional structure which carries the sensor array and optionally embraces the permanent magnet in the manner of a mount, and the mount and the terminal conductor tracks are first stamped out from a metal sheet as a gridlike developed form, and then deformed to form the mount.
