“…The modern literature on the LVR motor is quite limited and does not target experimental implementation. In [5,6], an analysis and magnetic circuit model of the LVR motor are discussed. As for control system development of the LVR motor, optimal excitation current control, force control and position control implemented on simulation software are presented in [7][8][9].…”

The objective of this paper is to design and implement a direct-drive position control based on a simplified sinusoidal flux model for a linear variable reluctance motor. The motor under consideration is a three-phase linear reluctance motor with strong magnetic coupling between phases that has the advantages of simple structure, compactness and low cost with no permanent magnet. The experimental results show overall good performance indicating that the developed system can be considered as a strong candidate for high precision manufacturing automation applications.

Abstmcl-This paper explores the design of excitation current profiles for a type of threephase magnetically COUpled linear variable reluctance motor. A model relating force production to air gap geometry is derived using magnetic circuit analysis under an assumption that flux flows across the air gap through tubular paths bounded by straight lines and circular arcs. Constrained Optimization techniques are used for two purposes: first, to determine the motor's continuous force limit corresponding to some given continuous current limit; second, to determine currents that Batisfy the current limits and produce e deslred force with minimum power dissipation. The optimization results indicate that a 6-wire Connection is preferable to a 3-wire connection, and that wide teeth are preferable to narrow teeth, if the goal is to maximize the range of ripple free force.
