Abstract

The invention discloses a modeling analysis method for force characteristics of a unilateral composite secondary linear induction motor. According to the invention, the simplified two-dimensional four-region electromagnetic model of the unilateral composite secondary linear induction motor is established. The magnetic field is analyzed based on the classical electromagnetic field theory. The expression of the thrust and the normal force of the motor is acquired. The relations among thrust, normal force, input current amplitude, frequency and slip ratio are studied, theoretical calculation correctness is well verified by comparing the relation with 2D and 3D finite element analysis and experimental platform test results, and the method is simple in analysis process, small in calculation amount and suitable for engineering calculation and lays a foundation for linear induction motor design.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic field analysis of linear induction motors, and in particular relates to a method for modeling and analyzing the force characteristics of unilateral composite secondary linear induction motors. Background technique [0002] Single-side linear induction motor (single-side linear induction motor, SLIM) is widely used in rail transportation systems and maglev trains due to its simple structure, linear motion without intermediate transmission, high reliability, and good heat dissipation. . The Vancouver Sky train system developed by Canada's Bombardier Corporation, the Toei Line 12 of the Tokyo Metro in Japan, the Guangzhou Metro Lines 4, 5, and 6 in China, and the Beijing Airport Line all adopt this type of structure. [0003] However, the analytical model of the mechanical characteristics of the unilateral compound secondary linear induction motor has problems such as difficulty in construct...
