A general framework for the analysis and design of tubular linear permanent magnet machines [PDF]
, 1999 A general framework for the analysis and design of a class of tubular linear permanent magnet machines is described. The open-circuit and armature reaction magnetic field distributions are established analytically in terms of a magnetic vector potential ...

Modeling and control design simulations of a linear flux-switching permanent-magnet-levitated motor
Mechanical Engineering Journal, 2017 For flux-switching PM (FSPM) motors, permanent magnets (PMs) are placed in the stator and not in the rotor structure as in the majority of PM motor designs. Recently, FSPM bearingless motors have been developed for special applications.

The Bearingless Electrical Machine [PDF]
Electromagnetic bearings allow the suspension of solids. For rotary applications, the most important physical effect is the force of a magnetic circuit to a high permeable armature, called the MAXWELL force. Contrary to the commonly used MAXWELL bearings,
