Research of Linear Induction Motor as Part of Driver by Detailed Equivalent Circuit

Abstract

The technique and key results of the mathematical simulation of a linear induction motor as a part of a church bell's electric driver are described in the paper. Linear induction motor comprises two flat inductors with a flat secondary element between their active sides and connected with the bell's bowl. When the motor is connected to a three-phase circuit, the secondary element moves translationally causing deflection of bell's bowl. The motor control system assigns a motor oscillation algorithm. The mathematical model of the motor is developed using electrical and magnetic detailed equivalent circuits and implemented in the Simulink environment of Matlab package. The peculiarities of bell's bowl oscillating processes are considered in the process of direct and reduced-current motor starting.
