Today, superconductor materials are widely used in electric machines because of their unique properties. This has been always a question for designers and researchers whether super-conductors can be a good substitute for Permanent Magnet (PM) or not. In this paper, the performance of a dual stator linear vernier machine under identical conditions in the presence of High-Temperature Superconductor Bulk (HTS-Bulk) and PM are analyzed and compared. HTS-Bulk and PM are located between the slot of the stator to illustrate the advantages and disadvantages of the superconductor. The performance of both machines is based on the magnetic gear effect which due to the existence of numerous magnetic pole pairs is able to generate relatively high thrust force at very low speed. The main parameters of both machines such as: air gap flux density, PM flux, back-EMF, self-inductance, mutual-inductance, power factor, detent force and thrust force have been compared to each other at the same geometry by finite element method.

如今，超导材料因其独特的性能而广泛用于电机中。对于设计人员和研究人员而言，这一直是一个问题，超导体是否可以很好地替代永磁体（PM）。本文分析并比较了在高温超导体（HTS-Bulk）和永磁体存在的条件下，双定子直线游标机在相同条件下的性能。HTS-Bulk和PM位于定子的槽之间，以说明超导体的优缺点。两种电机的性能均基于电磁齿轮效应，由于存在许多磁极对，因此能够以非常低的速度产生相对较高的推力。两台机器的主要参数例如：气隙磁通密度，PM磁通，
