摘要： A connection support assembly for a stator assembly can be used to secure electrical jumper wires of an electric machine. The connection support assembly includes a support body and a catch protruding from the support body. The catch defines an opening. The connection support assembly further includes a clip coupled to the support body. The clip includes a clip body and a pin protruding from the clip body. The pin extends through the opening of the catch in order to couple the clip to the support body and clamp at least some electrical jumper wires between the support body and the clip.

摘要： A method and assembly for forming a rotor include forming a rotor core having a plurality of voids and placing the formed rotor core into a die cavity. The method includes moving a plurality of support shoes to define an outer diameter of the die cavity, and injecting at least one of the plurality of voids with a magnetic slurry. At least one permanent magnet is formed from the magnetic slurry by applying pressure to the rotor core and the magnetic slurry within the die cavity and by applying a magnetic field to align the magnetic slurry. After forming the at least one permanent magnet within the rotor core, the plurality of support shoes are retracted and the rotor core removed with the at least one permanent magnet formed therein.

摘要： An electric device and a stator assembly for the electric device includes a stator core defining a plurality of slots spaced from each other. The stator assembly includes a plurality of bar conductors disposed in each of the slots and arranged to present a first winding path, a second winding path and a third winding path. A first set of the bar conductors of the first, second and third winding paths are configured to receive current in a parallel circuit arrangement. The stator assembly also includes a plurality of electrical jumpers electrically connected to a predetermined number of the bar conductors such that an amount of current flowing through the first winding path and the third winding path is substantially the same and an amount of current flowing through the second winding path is different from the amount of current flowing through the first and third winding paths.

摘要： An improved rotor assembly configured for magnets with differing lengths, and methods and systems for manufacturing the same. The rotor assembly may be created by selectively creating first and second tabs extending into apertures of lamination sheets. The first and second tabs may be selectively removed, depending on the different magnet lengths and the specific lamination sheet, according to one of a first finishing schedule and a second finishing schedule. The lamination sheets are stacked with any remaining first and second tabs, and other features, aligned.

摘要： An electric machine includes a stator core defining a number of stator slots (Z). A rotor assembly is positioned at least partially within the stator core. The rotor assembly includes at least one permanent magnet and defines a number of poles (M). A plurality of stator windings are positioned in the number of stator slots and define a number of phases (M). The machine defines a non-integer slots per pole per phase value (X), which is expressed as a mixed fraction in the form of A.(B/C), where A, B and C are integers. Optimal configurations for the electric machine are specified that maximize torque while minimizing torque ripple, noise and manufacturing complexity. In one embodiment, the slots per pole per phase value (X) is 2½. In another embodiment, the slots per pole per phase value (X) is 3½.

摘要： Presented are electric machines with optimized stator tooth geometries and multi-gauge stator conductors, methods for making/using such electric machines, and motor vehicles equipped with such electric machines. An electric machine includes a housing, a rotor assembly rotatably attached to the housing, and a stator assembly coaxial with and separated by an airgap from the rotor assembly. The rotor assembly includes one or more magnets mounted to a rotor core. The stator assembly includes a stator core with multiple axially elongated, circumferentially spaced stator slots, multiple radially aligned stator teeth interleaved between and separating the slots, and multiple electromagnetic windings wound through the slots. Each stator tooth has an elongated tooth body with a tooth head at a radial end of a tooth root, which attaches to a cylindrical hub of the stator core. The tooth head has an axial cross-section with a trapezoidal crown integral with a rectangular tip.
