Design and Research of Permanent Magnet Limited Angle Torque Motor
With the rapid development of multi electric aircraft and the urgent need for lightweight and high efficiency ac-cessories,the application of limited angle torque motor in aircraft air bleed system is increasingly urgent.On the one hand,the limited angle torque motor can significantly simplify the structure of the high-temperature air bleed control valve and reduce the volume;on the other hand,it can also realize the on-demand adjustment of the air bleed pressure and temperature based on the system demand,reducing the fuel compensation loss.In order to solve the problem that it is dif-ficult to predict the working characteristics of the high-temperature limited angle torque motor,the mathematical model and simulation model are established,and the accuracy of the simulation model is verified through physical tests.The re-search results provide a reference for the research on the characteristics of limited angle torque motor.
