1. A system configured to harvest electrical energy from an electric actuator driving a rotating machine, the system comprising:
an AC phase harvesting device configured to harvest electrical energy from the electric actuator;
a thermo-electric energy harvesting device configured to harvest heat energy from the rotating machine;
a resistor electrically connected to the thermo-electric energy harvesting device, wherein at least a first portion of the electrical energy harvested by the AC phase harvesting device is used to provide an electrical current to the resistor, the electrical current heating the resistor, and heat from the resistor being harvested by the thermo-electric energy harvesting device;
a harvesting manager circuit configured to receive power from the thermo-electric energy harvesting device, wherein the harvesting manager circuit is electrically connected to the AC phase harvesting device and a second portion of the energy from the AC phase harvesting device is transmitted to the harvesting manager circuit;
an energy storage device configured to store power transmitted from the harvesting manager circuit; and
a power distribution manager circuit configured to transfer power from the energy storage device to a wireless sensor bundle associated with the rotating machine.
