Abstract
An apparatus comprises a stator coil for conducting an electrical input current to activate the stator coil. A magnetic structure is for magnetically interacting with the stator coil to produce mechanical output power and is electrically isolated from the stator coil. The mechanical output power is output by an output shaft fixed to the magnetic structure. The apparatus further comprises a pickup coil configured to be electromagnetically coupled to the stator coil and the magnetic structure to induce an electrical output current. The output current is output by an output line electrically connected to the pickup coil. An electrical load is electrically connected to the output line to be powered by the electrical output current.
