A method for calculating the performance of double-sided linear induction motor (DLIM) with short secondary is presented in this paper. The analytical solution of air gap flux density is firstly deduced from one-dimensional (1-D) electromagnetic field equations, then in the equivalent circuit of the motor, to take both longitudinal and transverse end effects into account, the correction coefficients...
This paper aims to present a new approach including the magnetizing branches related to each winding's terminal of multi-windings traction transformers. The mathematical background of this model is described. The determination of the different elements constituting the scheme is made through a finite-elements calculation of the main as well as the leakage inductances of the different windings (case...
This paper presents the techniques used to optimise the geometry of electrostatic micromotors for maximum average torque. The optimisation of the geometry is done under consideration that the excitation is also optimised for maximum average torque. The most important part of this optimisation is automation. Automation of the mesh generation for the finite element calculation, and of the equivalent...
