Electrical Power Distribution System with Electronically Commutated Motor and Generator for Efficient Accommodation of Starting and Running Loads

Abstract

An electrical power distribution system and method are provided for efficiently accommodating disparities between starting and running loads without requiring an oversized primary power source. The system comprises a battery configured to provide a power supply, an electronically commutated motor (ECM) driven by the battery, a transmission gearbox mechanically coupled to the ECM to increase its rotational speed, an electronically commutated generator (ECG) driven by the gearbox to generate an output current, a charging circuit to recharge the battery with the ECG output, and an output to provide the ECG current to a load. The ECM includes a first coil stator and a first permanent magnet rotor, while the ECG includes a second permanent magnet rotor driven by the gearbox and a second coil stator.
