Simultaneous Consideration of Finite Length and Finite Width of Linear Induction Motors

This paper compares the performances of single layer and double layer motor. It establishes the expression of thrust in the form of an integral. An arbitrary extension of the magnetic circuit in the direction of motion is used in two different ways, which are compared. The finite width of the secondary, and the curvature of the secondary current lines are considered. Forces normal to the air gap are evaluated. The mathematical method is the use of the Fourier transform in such a way that the properties of every wavelength is considered.
