Abstract

This paper presents the design and optimization of a high-efficiency permanent magnet synchronous alternator with the desired output power of 2 kW at 6 krpm applying to the truck power system. This kind of alternator requires low output voltage and high current. In order to effectively increase the overload power handing capability and efficiency of the designed alternator, the low torque angle is selected at the rated power and speed in the design. Key design methodologies and procedures are introduced and analyzed in detail. The corresponding finite element analysis (FEA) model is built. Structure optimization includes stator and rotor structure size, permanent magnet size, magnetic bridge and air gap length which are analyzed and simulated by ANSYS Maxwell 2D FEA. Thermal analysis is conducted, and the housing of alternator is designed. The alternator prototype is fabricated and tested based on our design. The simulation and test results verified the performance of the alternator.
