| Abstract: | This paper analyzes the principle of the rotation permanent magnet eddy current braking firstly.Taking subway vehicle as an example,it designs a type of the brake＇s structure.Then,it analyzes the brake＇s magnetic field and gets the law of distribution of magnetic flux density with the help of ANSYS which is a finite element analysis software.Afterward,on the basis of the electromagnetic field theories,it calculates this brake＇s braking torque by analytical law.The conclusions got from this article provide some foundations for design and optimization as well as the control method of the rotation eddy current brake. |
