Analysis of Mechanical Dynamics and Flux Weakening Ability for a Variable Flux Axial Field Permanent Magnet Electrical Machine
摘要
Abstract
To a mechanically variable flux axial field permanent magnet electrical machine(MVFAFPMEM),the mechanical dynamics simulation and electromagnetic analysis are implemented in this paper to obtain the motion characteristic and angle adjustment capability of the mechanically device,as well as flux weakening ability of MVFAFPMEM.The cam angular acceleration and spring deformation are studied at different speed,so the stagger angle between the two rotors with rotor speed can be obtained by virtual prototype technology named Automatic Dynamic Analysis of Mechanical Systems(ADAMS).The air-gap flux distribution of MVFAFPMEM at different stagger angle is calculated by finite element method(FEM),and its electromagnetic characteristics are studied by adopting the mechanical flux-weakening device.The simulation results show that the stagger angle between the two rotors can vary from 0 to 21(deg)by this device,and a better flux weakening ability is obtained.The corresponding experiments are carried out to validate theory analysis,and it shows that the stagger angle between the rotors can be adjusted automatically by the rotor speed at a wide flux regulation range of MVFAFPMEM.关键词
