FEM simulace momentové charakteristiky asynchronního motoru

Abstract

Diploma thesis is focused to asynchronous motor and its mechanical design. Principle of operation, equivalent circuit, terminal block wiring and the parts of alternating current motor are described within as well. The main objective of thesis deal with simulation of torque characteristic using the finite element method in ANSYS Maxwell software. Theoretical analysis of torque characteristic is, along with mentioned real measurement methods, described. Simulation implementation was followed by the evaluation of torque characteristic which is based on synchronous and asynchronous moments. These are described in theoretical part of thesis. In examples are mentioned methods for suppressing parasitic and synchronous moments. Simulation was performed on one skew width of the rotor grooves and rotor positional matching without any rotation of grooves.
