Patent number: 11491861Abstract: An in-wheel electric motor includes at a vehicle side a connector stub, a stator body connected to the connector stub and on an outer surface equipped with stator windings, and further includes a rotor body coaxially enclosing the stator and rotatable around a rotation axis. The electric motor further includes a power electronics device for powering the stator and a detector for an angular position of the rotor body relative to the stator. The connector stub is provided with a support for coupling to the power electronics device which is mounted on the support inside the hollow stator body. The detector includes an angular position sensor mounted inside the hollow stator body and coupled to the rotor body wherein the detector is mounted on the power electronics device coaxially with the rotation axis.Type: GrantFiled: July 20, 2018Date of Patent: November 8, 2022Assignee: E-TRACTION EUROPE B.V.Inventor: Timothy Van Seventer

Patent number: 11309770Abstract: An in-wheel electric motor includes at a vehicle side an elongated connector, a cylindrical stator body connected to the connector and on an outer surface of the stator body equipped with stator windings, a cylindrical rotor body enclosing the stator, and a power electronics device powering the stator windings. The connector is provided with a first opening of a feed channel for coolant and a second opening of a return channel for coolant, each of the feed and return channels being parallel to an axial direction of the connector. The electric motor includes a cooling circuitry with a feed connector and a return connector for coolant, which circuitry includes a coolant supply channel that extends from the feed connector through first the power electronics device and subsequently through a cooling jacket that is situated at the perimeter of the cylindrical stator body and from there to the return connector.Type: GrantFiled: July 20, 2018Date of Patent: April 19, 2022Assignee: E-TRACTION EUROPE B.V.Inventors: Timothy Van Seventer, Reinhard Peter Van Der Wal
