Abstract: A rotating electrical machine of the double stator configuration includes a rotor shaped as a hollow cylinder disposed concentrically between an outer stator and an inner stator. The rotor can include plurality of radially spaced magnet cavities configured to receive permanent magnetic bars. To provide sufficient stiffness and rigidity, the rotor may be made from fiber composite material. To simplify construction, the rotor can be assembled from a plurality of rotor segments radially arranged about an axis line in which the magnet cavities are disposed.

Abstract: An electrical machine has a nonmetallic housing having a stator band and an endplate, wherein the laminated stator core is in self-locked engagement with the housing. Another electrical machine has a unitary nonmetallic housing with an integral stator band and an integral endplate, wherein the laminated stator core is over-molded with the housing. Yet another electrical machine has a unitary nonmetallic housing with an integral stator band and an integral endplate, wherein the laminated stator core is in engagement with the stator band with an interference fit.

Abstract: An electrical machine includes a stator and a rotor in magnetic communication with the stator. The rotor has a cage construction, the rotor having a plurality of passages extending therethrough from a first end of the rotor to a second end of the rotor. A rotor cage has two end rings, one of the end rings disposed at each of the first end and the second end of the rotor, and having a plurality of conductor bars extending through the rotor from the first end to the second end and coupled with the end rings. The conductor bars each include a transition region adjacent to each end ring, and a central region disposed between the two transition regions. Each transition region includes at least one conductor bar dimension that increases proximate the end rings.

Abstract: A rotor assembly includes a rotor member and a plurality of permanent magnets. The rotor member has a hub with a central axis and a plurality of spokes extending radially outward relative to the hub. Each spoke has a radially inward end and a radially outward end. Each spoke also has a body section, a mounting section, and a flux barrier section. The body section extends from the radially outward end towards the radially inward end. The mounting section is interconnected to the hub. The flux barrier section is disposed between the body section and the mounting section and has at least one flux restriction web extending between the body section and the mounting section. The flux restriction web magnetically isolates the body section from the mounting section. A permanent magnet is disposed within each magnet-receiving slot between pairs of adjacent spokes. A motor with the rotor assembly is also disclosed.

Abstract: An electric machine includes a core comprising a plurality of core segments extending in a longitudinal direction and a plurality of slots being equally spaced peripherally around the core and formed between cutouts in adjacent segments. A plurality of windings is disposed on the core and includes straight portions disposed in the plurality of slots and turn portions extending past at least one axial end of the core along the longitudinal direction. The core and windings are assembled together in an unrolled condition, where the mat is placed in an unrolled core, and then rolled together to form a stator or rotor.

Abstract: A combined electric motor and motor drive are provided. The electric motor and motor drive are attached together to form a co-packaged unit. In the co-packaged electric motor and motor drive, both the motor drive and the electric motor generate heat. A thermoelectric cooler is provided that may transfer heat away from the motor drive. The thermoelectric cooler may also insulate the motor drive from the heat generated by the motor.
