Synchronní motor s permanentními magnety a zvýšenou odolností proti poruchám
Vaško, Dávid ; Mach, Martin (oponent) ; Vítek, Ondřej (vedoucí práce)
Táto diplomová práca sa zaoberá strojmi odolnými proti poruchám. V prvej časti je prebraná teória porúch elektrických strojov a možnosti zvyšovania poruchovej odolnosti najmä pre PMSM. V druhej časti je analytický výpočet hlavných rozmerov dvojitého trojfázového synchrónneho motoru s permanentnými magnetmi na povrchu potrebných pre vytvorenie modelu. V tretej časti sa práca zaoberá vytváraním modelu v programe ANSYS RMxrpt, Maxwell 2D a Motor-Cad a porovnávaním výsledkov. V štvrtej časti bol stroj optimalizovaný na čo najväčšiu momentovú hustotu pri čo najvyššej účinnosti a postavený zjednodušený tepelný model vrátane olejového chladenia. Piata časť sa zaoberá simuláciami poruchových stavov: rozpojenie jedného trojfázového systému a jednofázový skrat. V šiestej časti bol navrhnutý motor s vnorenými magnetmi a simulovaný pri rovnakých poruchových stavoch.

Losses reduction of single-phase induction motor
Vaško, Dávid ; Mach, Martin (oponent) ; Vítek, Ondřej (vedoucí práce)
Bachelor thesis Losses reduction of single-phase induction motor deals with issues of increasing the efficiency of single-phase induction motor JMO90-4S-90 from EMP s.r.o. Slavkov near Brno. The first part deals with the theory of induction motors, especially single-phase motors and analysis of losses in induction machines. The second part deals with the introduction of motor solutions and methods used for loss reduction. In the third part, the thesis deals with the calculating selected parameters, the design of motors in RMxprt, and their modification for improving efficiency. The fourth part deals briefly with the design of motors in Ansys Maxwell, comparison of results obtained from Maxwell and RMxprt with the results from measurement for motor JMO90-4S-90 and comparison of results from Maxwell and RMxprt for other motor solutions.
