Simulation and Analysis of Single-Rotor Dual-Stator Radial Flux Dual-Voltage Permanent Magnet Generator for Military Application

Dual-stator single-rotor (DSSR) machines are designed to generate two different output voltages independently and simultaneously. These generators are finding their place in various directly coupled engine-driven applications due to their better performance and efficiency. In this study, a dual-stator permanent magnet (PM) generator for auxiliary power generator applications has been modeled and analyzed [finite-element method (FEM)] using MagNet software. Various possible rotor configurations based on the mounting of PMs on the rotor between the two stators, their size, and shape were considered. The rotor configuration that establishes better air-gap flux density with ease of manufacturability is identified. Simulation results are presented and discussed.
