A motor includes a rotor, a stator, a bearing, a motor housing, a bearing holder, and a bus bar. The rotor includes an axially extending shaft. The stator radially opposes the rotor. The bearing rotatably supports the shaft. The motor housing accommodates the stator and opens to one axial side. The bearing holder holds the bearing and covers the opening of the motor housing. The bus bar is connected to the conductive wire drawn out from the stator and is located on the bearing holder. The bearing holder includes a recess radially outside of the bearing and including an upper surface recessed to the other axial side. The bus bar includes a base portion and a connection portion. The base portion is located radially outside of the recess and extends in the circumferential direction.

A power connector is provided that is configured to conduct a current. The power connector includes a base structure, an extension structure, and a connector head structure that define a current path for the current. The base structure is coupled to an output node of a primary conductor and receives the current from the primary conductor. The connector head structure is configured to output the current from the power connector to the load. The extension structure is coupled to and extends between the base structure and the connector head structure. The extension structure includes a current constriction region configured to increase a magnetic flux density of a magnetic field produced by the current flowing through the current constriction region at a position of a magnetic current sensor that generates a sensor signal based on the magnetic field magnetic field produced by the current flowing through the current constriction region.

Conventional axial flux motors typically include multiple rotors and stators resulting in a larger and heavier motor. Additionally, conventional axial flux motors include a housing to protect the rotors and stators, but the housing is often difficult to seal from the environment leading to risks of contaminants (e.g., dirt, water) infiltrating the motor and causing failure over time. The present invention overcomes these limitations by disclosing an axial flux motor with a single rotor and two stators. The use of a single rotor reduces the size and weight of the motor. An inboard housing and an outboard housing mechanically support the two stators and are joined together to define an interior cavity. A ring seal is disposed between the two housings to ensure the interior cavity is sealed. Additionally, the two stators may actuate multiple degrees of freedom (DOF) including the rotation of a wheel and actuation of a suspension.

An emotor connection arrangement for connecting power electronics of an electric or hybrid electric vehicle to an emotor. The emotor connection arrangement includes a junction box configured to extend from the power electronics to the emotor, and phase bars that extend in the junction box and electrically connect the power electronics to the emotor. A first access cover is removably connected to the junction box and configured to provide access for connecting the phase bars to the emotor, and a second access cover provides similar access for connecting the phase bars to the power electronics. In order to prevent overheating, the first access cover includes a cooling fluid channel with a cooling fluid inlet configured to be connected to a cooling fluid source and a cooling fluid outlet configured to be connected to a cooling fluid return.

An electric motor module includes: an electric motor; a printed circuit board; a gear that performs conversion such that an output shaft extends is orthogonal to a rotating shaft of the electric motor; a storage portion that houses at least the electric motor and the gear; and a connector storage portion that houses the connector and attached to an opening of the storage portion. A connection portion between the opening and the connector storage portion is inclined with respect to the rotating shaft on a plane perpendicular to the output shaft. The printed circuit board includes: a first portion parallel to the rotating shaft on the plane; and a second portion extending from one end of the first portion toward the rotating shaft. A connector is disposed at another end of the first portion, and a terminal is disposed in the second portion.

In order to improve a housing, in particular for an electrotechnical apparatus, comprising at least two housing parts which each have a connecting face, said connecting faces, in a closed state of the housing, facing one another along a connecting section, it is proposed that at least one of the at least two housing parts, along the connecting section, has at least one integrated protective section, in particular for EMC shielding and/or for mechanical protection.

In an embodiment, a motor is disclosed, comprising: a housing; a cover disposed on top of the housing; a stator disposed inside the housing; a rotor disposed inside the stator; a shaft coupled to the rotor; and a connector disposed on top of the cover, wherein the connector comprises: a connector body; and a shield terminal disposed on the connector body so as to be partially exposed, wherein the cover is formed of a metal material, and wherein the shield terminal is inserted into a hole in the cover so as to come into contact therewith. Accordingly, by using the shield terminal including a curved surface and the hole formed in the cover, a gripping force of the motor can be improved.
