Özet

This paper contains torque components identification of 3-phase induction machine. Electromagnetic torque and pulsating torque is calculated via a circular path integral of the Maxwell stress tensor which provides a convenient way of computing forces acting on bodies by evaluating a surface integral. Torque calculations are done by finite element method in ANSYS and MATLAB. Also there are identified a high harmonic components of calculated torque with additional asynchronous torque calculation. The torque identification has been verified experimentally on a laboratory machine using a special torque measurement system in the dynamic state. Whole measurement is processed by LabVIEW with using a special measurement card NI PCIe-6361 and torque measurement system with DATAFLEX 22/20.
