Equivalent Magnetic Circuit Analysis of a Novel Brushless Hybrid Excitation Synchronous Generator

The paper discusses a brushless synchronous generator combining induced excitation and permanent magnet. The structure and principle of the machine are introduced and an equivalent magnetic circuit (EMC) model is derived. The magnetic flux and the flux density of main parts of the motor obtained by the EMC are coincide well with those by the finite elements method and show clearly the effectiveness and practicability of the hybrid excitation.
