Title
Performance Optimization Analysis of Hybrid Excitation Generator With the Electromagnetic Rotor and Embedded Permanent Magnet Rotor for Vehicle
Abstract
To solve the problems of the non-adjustable magnetic field of the permanent magnet (PM) generator, large excitation loss and high failure rate of electric excitation generator, this paper proposes a parallel electromagnetic and PM hybrid excitation generator (HEG). The designed generator adopts a high power density PM rotor composed of built-in tangential PM steel and V-shaped PM steel and a salient-pole electromagnetic rotor (EMR) with short axial length, less electromagnetic loss, simple and reliable structure. By adjusting the axial length of two rotors and the size of magnetomotive force sources, the generator can adjust the rotor power distribution to meet various power requirements. Meanwhile, the HEG can adjust the electromagnetic magnetic field (EMMF) by adjusting the size and direction of the excitation current, and then can adjust the size of the synthetic magnetic field to achieve the purpose of stabilizing output voltage. In this paper, the magnetic circuit model of the HEG is established by using the equivalent magnetic circuit (EMC) method, and the rationality of the designed magnetic circuit is verified and analyzed by the finite element method. The prototype is trial-manufactured and tested, and the results show that the designed HEG has a wide magnetic regulation range, stable output voltage, and good output performance.
