Efficiency Improvement of Three Phase Induction Motor
Žák, Ondřej ; Mach, Martin (referee) ; Vítek, Ondřej (advisor)
This bacelor thesis looks into problematics of efficiency of induction elektromotors. Due to present tendence of permanently encreasing efficiency, this topic is very actual. How to encrease efficiency but not to encrease material and production cost too much? This is the daily question of every producer of induction elektromotors. This thesis has a target to bring closer understanding of this problematics and describe alternatives, which is possible to follow. On choosen elektromotor produced by ATAS elektromotory Náchod a.s. is made an comparison of analytic calculate, calculate of software RMxprt and Maxwell 2D and real measuring, which refes about limits of individual calculatin methods. Then the design of changes with new calculate is provided and comparison of all results.
