Abstract
An electric machine may include a housing that encloses both a radial motor producing radial flux in a first direction, the radial flux influences a first magnetic unit to produce a first torque on a rotor arm attached to a shaft. The housing can also include an axial motor producing axial flux in a second direction to influence a second magnetic unit to produce a second torque on the rotor arm attached to the shaft, wherein the radial motor and the axial motor are positioned in the housing to reduce cross magnetic flux from either the radial motor or the axial motor. The primary radial motor can include either a permanent magnetic motor or an induction motor. The secondary radial motor can include one of a permanent magnet motor, an induction motor, or a transverse flux motor. The current and phase of primary and secondary motors can be independently controllable.
