Abstract

In this paper, linear induction motor is analyzed by 3-D finite-element method (3-D FEM) to consider influence of construction of secondary reaction plate on the transverse edge effect. A effective 3-D analysis model for considering the transverse edge effect caused by the finite widths of the primary and the secondary is not only proposed, but also the simple method measuring the transverse edge effect by using the patterns of currents induced in the secondary reaction plate is proposed. With this effective analysis method, various models with overhang and cap have been analyzed to consider the relationship between the construction of secondary reaction plate and the transverse edge effect.
