Additional asynchronous and pulsating torque analysis of 3-phase induction machine

摘要

This document contains possibilities of additional asynchronous torque development due to the high harmonics and their general derivation. Also, there is calculated a pulsating torque of 3-phase induction machine with power 1.1kW from electromagnetic field and example of additional asynchronous torque calculation. Whole analysis is done by finite element method in ANSYS. The torque is calculated via a circular path integral of the Maxwell stress tensor. The Maxwell stress tensor provides a convenient way of computing forces acting on bodies by evaluating a surface integral.
