Design and analysis of a novel linear transverse flux permanent magnet motor using HTS magnetic shielding

Abstract—In this paper, a novel linear transverse flux perma-nent 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 de-signed with minimum cogging force and maximum thrust force. Then, by employing finite element analysis, the advantages and va-lidity of the proposed motor are verified.
