Abstract: An electric machine includes a stator having a plurality of stator teeth. Each stator tooth of the plurality of stator teeth includes a winding disposed there around. Each stator tooth of the plurality of stator teeth is shaped to receive a plurality of microchannels. The microchannels contain a circulating heat-transfer fluid; Each stator tooth of the plurality of stator teeth is thermally exposed to the heat-transfer fluid via the plurality of microchannels so as to effectuate heat removal from each stator tooth of the plurality of stator teeth.

Abstract: An electric machine includes a stator having a stator winding disposed thereon. A rotor is electromagnetically exposed to the stator. A field winding and an induction winding are disposed on the rotor. A rectifier is electrically coupled to the induction winding and the field winding. Upon application of a voltage to the stator winding, the stator winding produces a first rotating magnetic field and a second rotating magnetic field that has a different spatial frequency than the first rotating magnetic field. The first rotating magnetic field interacts asynchronously with the induction winding to produce an alternating current in the induction winding. The rectifier changes the alternating current to a direct current that is supplied to the field winding. The field winding interacts synchronously with the second rotating magnetic field.

Abstract: Aspects of the disclosure relate to a cycloidal magnetic gear. The cycloidal magnetic gear includes an outer rotor. A plurality of magnetic pole pairs is disposed on an inner circumference of the outer rotor. A first, second, and third inner rotor is disposed within the outer rotor. The first, second, and third inner rotors includes a magnetic pole pairs disposed on an outer circumference thereof. The first inner rotor and the third inner rotor have a thickness of approximately half the thickness of the second inner rotor. The first inner rotor, the second inner rotor, and the third inner rotor balance moments acting on a drive shaft.

Abstract: In some aspects, a magnetic gear system includes a flux focusing magnet arrangement having a low-pole count rotor, a pair of modulator rotors disposed on either side of the low-pole count rotor, and a pair of high-pole count outer rotors disposed outside of the pair of modulator rotors. In some aspects, a magnetic gear system includes a motor with a stator and a pair of low-pole count rotors disposed on either side of the stator. The magnetic gear system further includes a pair of modulator rotors disposed on either side of the motor, and a pair of high-pole outer rotors disposed on opposite sides of the pair of modulator rotors.
