直线型磁通切换电机特性分析的时步有限元模型
Time-step finite element model for operational characteristics analysis of LFSPM
摘要
Abstract
In response to the relatively complex structure and insufficient research on the operating characteristics of double-sided linear flux switched permanent magnet motors(DLFSPM),a field-circuit coupling analysis model for studying the operating characteristics of DLFSPM is established by using time step finite element method as a tool.The motor-operation principle of DLFSPM is described,and the operating characteristic equation in ABC coordinate system is derived.A simulation topology for circular-arc motors is established to address the issue of open domain processing in the simulation environment of linear motors.Taking a DLFSPM prototype with a rated electromagnetic thrust of 400 N as an example,the field-circuit coupling time-step finite element model is obtained that can simultaneously consider the internal magnetic field and external circuit characteristics of the DLFSPM.The time step finite element analysis model is used to study its no-load characteristics and force angle characteristics.The comparison curve results between simulation and actual measurement show good agreement between the two,indicating that the model has good computational accuracy and further verifying its correctness and effectiveness.关键词
