Segmented magnetic core
Various embodiments associated with a segmented magnetic core are described. The segmented magnetic core can be made up of multiple singular structures so as to allow an individual singular structure to be removed with ease and without disturbing another magnetic core. This modular core design allows for a significant reduction in motor housing weight due to compatibility of the design with lightweight materials and the potential absence of extensive housing when so designed. This modular core design can be incorporated into a motor or a generator and this modular core design can be accomplished, in one example, by way of stacking and/or interlocking employing low cost assembly. In one example, a motor or a generator uses sensors to detect an operational failure in a magnetic core, notifying a user early of the failure.

Terminal connector assembly with an overmolded unit with coil end windings
A vehicle electric machine assembly including a stator core and a terminal block is provided. The stator core includes one or more three-phase terminals connected to end windings. The terminal block includes a connector for each of the three-phase terminals. A portion of the end windings extending from the stator core, the three-phase terminals, and the terminal block are overmolded as a single unit such that a portion of each of the connectors is exposed for connection to an inverter. The terminal block may further include one or more threaded apertures, each sized to receive a threaded stud to facilitate an electrical connection between one of the one or more three-phase terminals and the inverter. Each of the one or more three-phase terminals may extend axially along an axis substantially parallel to a central axis of a rotor disposed within a cavity defined by the stator core.
Double/twin radial air gap permanent magnet brushless motor
A twin radial air gap permanent-magnet-on-rotor brushless motor with a rotor comprising two magnet rings and a stator comprising individual iron-core-based stator pole modules containing a wound stator pole element with outward facing and inward facing radial pole surfaces, co-planar with the two magnet rings across the twin radial motor operating air gaps. Pole modules are mounted in a circular array upon an insulating surface or printed circuit board in automatic assembly operations interconnecting field coil windings in the desired pattern and including other electrical control components, with pole modules centered on the motor rotation axis and predominantly enclosed by the rotor. Field coil windings are supported by insulating bobbins located around the radial extent of the stator pole elements between the outer and inner facing radial pole surfaces with electrical means for connection to the electrical interconnection function supplied with the insulating surface or circuit board.
MEDIA GAP MOTOR FOR A TURBOCHARGER
The present disclosure relates to a media gap motor for a turbocharger. The proposed media gap motor contains a rotor and a stator, wherein the stator comprises multiple fins which extend from an inner portion radially towards the rotor in a flow chamber formed between the stator and the rotor. The fins do not extend by means of their inner portions as far as the rotor, and therefore a gap is formed between an inner end of the fins and the rotor, wherein in internal diameter of the fins is at least 1.2 times and at most 3 times an external diameter of the rotor.
