Publication number: 20230291264Abstract: A dynamo electric machine stator which is easy to assemble, includes a stator body with stator grooves and a winding mat with groove sections arranged in the stator grooves and lie one over the other in different radial positions, and with head sections which connect the groove sections. A wave winding conductor changes position by precisely one radial position in the stator grooves in the center of the extension of the wave winding conductor in the winding direction. The winding mat includes a first sub-winding mat with one first set of wave winding conductors for each section, the first sets being joined together in an X-shaped manner in the region of the position change such that the conductors are aligned in a specific manner at the intersections between the wave winding conductors.Type: ApplicationFiled: June 16, 2021Publication date: September 14, 2023Applicant: Schaeffler Technologies AG & Co.

Publication number: 20230231454Abstract: An electric machine designed as a permanently excited synchronous machine, including a rotor with a rotor body arranged on a rotor shaft, a stator, and a displacement device that generates a relative axial movement between the rotor body and the stator based on a torque produced between the rotor shaft and the rotor body. The displacement device has first and second displacement elements and at least one rolling body arranged between the first and second displacement elements. The first displacement element is axially movable and rotatable to a limited degree on the rotor shaft, and the second displacement element is connected to the rotor shaft rotationally fixed. The displacement elements provide that upon rotation of the first displacement element relative to the second or vice versa, the rotor body is pushed on the rotor shaft axially against the spring force.Type: ApplicationFiled: May 3, 2021Publication date: July 20, 2023Applicant: Schaeffler Technologies AG & CO.

Patent number: 10136474Abstract: A heat generating element for an electrical heating device of a motor vehicle, including at least one PTC element and two contact plates which are in contact with opposite sides of the PTC element and are provided on their outer side facing away from the PTC element with an insulating layer. Shielding is provided, comprising a first shell-like shielding plate and a second shell-like shielding plate which are each provided on the outer side of the insulating layer and are connected thereto in a thermally conductive manner. The longitudinal wall sections, directed towards one another, of the first and second shielding plate form an overlapping region. In order to reduce EMC problems, two shielding plates are sealed by way of an adhesive which is received in one of the two shielding plates and into which the end of a rim of the other shielding plate dips.Type: GrantFiled: July 10, 2013Date of Patent: November 20, 2018Assignee: Eberspacher catem GmbH & Co.

Patent number: 9398641Abstract: An electrical heating device for a motor vehicle includes a frame that has openings formed on oppositely situated sides for the passage of a medium to be heated, a layer structure, arranged in the frame, and a connecting housing. The layer structure comprises layers of corrugated-rib elements and heat generating elements, and each heat generating element has at least one PTC element arranged between parallel contact plates. At least one power dissipation generating power switch is provided in the connecting housing. A heat sink lies exposed on the outside of the connecting housing. Improved and adequate cooling of the electrical heating device having the power switch is created as a result of the insertion of the heat sink into the connecting housing in a sealing manner.Type: GrantFiled: December 21, 2012Date of Patent: July 19, 2016Assignee: Eberspächer catem GmbH & Co. KGInventors: Franz Bohlender, Michael Niederer, Christian Morgen

Patent number: 9338831Abstract: A heat generating element for an electrical heating device of a motor vehicle includes a positional frame which forms a receptacle in which a PTC element is accommodated, and two contact plates abutting on oppositely situated sides of the PTC element. A heat generating element has a sheet metal cover that is connected to the positional frame. Also provided are a frame, which has oppositely situated side openings for the passage of a medium to be heated, and a layer structure, which is arranged in the frame and which comprises layers of corrugated-rib and heat generating elements, such that the heat generating element has at least one PTC element arranged between two parallel contact plates. The electrical heating device is protected against EMC via sheet metal covers that are arranged on both sides of the heat generating element and between the corrugated-rib elements and the contact plates.Type: GrantFiled: December 21, 2012Date of Patent: May 10, 2016Assignee: Eberspächer catem GmbH & Co.
