A coil component for an electric machine, having a carrier and a coil winding accommodated in the carrier at least in sections. The carrier has a ring region with multiple grooves distributed in a circumferential direction, and multiple winding sections of the coil winding are received in each groove. An insulation layer is arranged between the carrier and the winding sections in at least one groove and projects with two extension portions over the winding sections towards a radial opening of the at least one groove. A closure element is received in the carrier in the groove with the insulation layer towards the radial opening, and both extension portions are arranged such that the closure element is spaced apart from the carrier by the extension portions. An electric machine is provided with the coil component.

Coil component having a closure element without direct contact to the carrier; and electric machine

An electric machine for driving a motor vehicle, having a stator and a rotor, rotatably mounted relative to the stator. The stator or the rotor is equipped with a winding receptacle region having a plurality of radially extending longitudinal slots distributed in a circumferential direction. Each longitudinal slot has with an opening toward one radial side, the width of which opening is delimited by two ends of two tabs directed toward each other in the circumferential direction, wherein each longitudinal slot has, between a chamber region receiving a plurality of conductors and the two tabs, at least one shoulder reducing a width of the chamber region, the conductors being supported in a radial direction on the at least one shoulder.

An electrical machine for driving a motor vehicle includes a housing, a stator, which is fixedly accommodated in the housing, and a rotor, which is mounted rotatably relative to the stator. The stator has a laminated core composed of a plurality of punched lamination segments and has a wire winding region connected to the laminated core. Each lamination segment has, on its radial exterior, at least one radial recess also created by means of the punching production. A coolant guide channel is delimited directly by an outer periphery of the laminated core. A recess of a first lamination segment is spaced apart, along the outer periphery, from a recess of a second lamination segment directly abutting the first lamination segment in such a way that the recess of the first lamination segment is at least partly axially covered by an end face of the second lamination segment.

An electric machine for a drive of a motor vehicle, having a stator, a rotor which can be rotated relative to the stator, a temperature sensor arranged and designed to capture a temperature of the stator and a rotor condition capture sensor which is arranged and designed to capture a rotational speed and/or rotational position of the rotor accommodated in a stator-fixed manner. The temperature sensor and the rotor condition capture sensor are implemented as subsystems of a common sensor system, wherein a first subsystem having the temperature sensor has an elastic thermally conductive contact element connected to the temperature sensor, which contact element is permanently fitted to a contact region of the stator. A hybrid module having this electric machine is also provided.
