Design and Analysis of a Novel Linear Transverse Flux Permanent Magnet Motor Using HTS Magnetic Shielding
In this paper, a novel linear transverse flux permanent magnet (TFPM) motor is proposed, which can offer higher thrust force, lower cogging force and easier manufacturing than its counterpart. The key is to propose a new C-shaped TFPM motor topology with the use of HTS bulks. After deriving the expressions of cogging force and thrust force, the proposed motor can be designed with minimum cogging force and maximum thrust force. Then, by employing finite element analysis, the advantages and validity of the proposed motor are verified.
