In this study, a novel 6‐degree of freedom compact carrier using magnetically levitated transverse flux permanent magnet linear synchronous motor is proposed and initial design characteristics are analysed. Motor structure is compact with magnetic iron cores for thrust and levitation, arranged orthogonally. This allows reduced magnetic coupling between linear synchronous motor (LSM) and electromagnets despite their close proximity. Such configuration also ensures independent design for propulsion and suspension. Furthermore, by virtue of the proposed configuration, yaw and lateral motion are inherently stable, leaving the required active actuators to merely four for thrust, pitch, roll, and heave active control. Preliminary characteristics are analysed using 3D finite element method and performance considerations for the simultaneous design of LSM and electromagnets are discussed thoroughly.
