Abstract
A brushless electric machine includes a housing, a stator assembly, a rotor assembly, a rotary transformer, and a rectifier. The stator assembly is arranged within the housing and includes a stator winding provided on a stator core. The rotor assembly is also positioned within the housing with an airgap separating the rotor assembly from the stator assembly. The rotor assembly includes a rotor shaft, a rotor winding, and a balance ring. The rotary transformer is positioned within the housing and includes a primary coil and a secondary coil. The rectifier includes a plurality of diodes positioned on the balance ring. The rectifier is electrically connected between the secondary coil and the rotor winding.
