| Abstract: | In this paper,a new kind of brushless all-air-core passive compulsator based on Halbach array was designed.The distribution of the magnetic field was analyzed,and the analytical equation of the magnetic flux density were deduced before the solution was gained.The magnetic field of the Halbach array CPA and the traditional CPA were also simulated and compared using the ANSYS software.It demonstrates the advantages of this design and verifies the feasibility of the design. |
