Connection unit for a stator with a stator winding having a number N of phases, having first to Nth contact portions, which are each designed for electrically conductively contacting one of N connection portions of the stator, form a receiving chamber for receiving one of the connection portions and have a guide. A respective contact portion has a wall, which limits the receiving chamber on one side, and the guide of the contact portion has a wall, which adjoins the wall of the contact portion and is bevelled with respect to the wall of the contact portion in a manner facing away from the receiving chamber. A conductor arrangement, which either electrically conductively connects the first to Nth contact portions or comprises N conductor portions, which are electrically isolated from one another and are each electrically conductively connected to one of the contact portions.

Connection unit for a stator, stator arrangement for an electric machine, method for producing a stator arrangement, and electric machine for driving a vehicle

Connection device for a stator having a stator winding, including N phases, first and second connection units which each comprise N contact portions and a conductor arrangement. The contact portions of the first connection unit are each designed for electrically conductive contacting of one of N connection portions of the stator winding, and the conductor arrangement of the first connection unit electrically conductively connects the contact portions of the first connection unit. The contact portions of the second connection unit are each designed for electrically conductive contacting of one of N further connection portions of the stator winding and the conductor arrangement of the second connection unit comprises N conductor portions, which are electrically insulated from each other and are each electrically conductively connected to one of the N contact portions of the second connection unit. A fastening mechanism permits the connection units to be detached and fastened.

Connection device for a stator, stator arrangement for an electric machine, method for producing a stator arrangement and electric machine for driving a vehicle

A stator for an AC motor, includes windings of a first layer, which extend over a first region of the stator and are connectable to a first phase, and windings of a second layer, which extend over a second region of the stator and are connectable to a second phase, wherein the first region is offset relative to the second region and at least one overlap region is formed which is smaller than the individual regions, and wherein a temperature detection unit is arranged in the overlap region and is designed to measure the temperature of the windings in the overlap region.

Stator with a temperature detection unit for an electric motor

A temperature detection unit for a stator of an electric motor, includes a plate, a support element, at least two feet, and at least two temperature sensors, wherein the temperature sensors are arranged one on each of the feet.

Exchangeable temperature detection unit for a stator of an electric motor

A contact ring for a stator of an electric motor has three planes, i.e. a first plane with at least one first conductor; a second plane made of an electrically insulating material; and a third plane with at least one second conductor, and at least one first and one second feedthrough passing through the second plane. The first feedthrough is smaller than the second feedthrough, and the first feedthrough guides coil wires of one coil and the second feedthrough guides coil wires of at least two coils.
