单相永磁力矩马达的力矩转角特性
Torque-angle Characteristics of Permanent Magnet Torque Motor with Single-phase Excitation
摘要
Abstract
In order to solve the problem that conventional electro-mechanical converter of 2D valve had deficiency of complicated magnetic circuit and structure,a single-phase excited magnetic circuit with axial asymmetrical topology is proposed,and based on that a novel permanent magnet torque motor is developed.Firstly the equation of torque-angle characteristics is derived via analytical method,then a finite element analysis model is built to describe magnetic field distribution,and therefore numerical results of torque-angle characteristics are obtained.Prototype motor is designed and fabricated based on numerical simulation.The experimental rig is built up to study torque-angle characteristics.The experimental results agreed well with simulations,which indicates prototype motor has large magnetic torque and its torque-angle characteristic is close to linear relationship whose amplitude increases with excited current.The proposed motor is appropriate to be electro-mechanical converter of 2D three-way valve and other similar control components.关键词
