1. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps. LÄS MER
2. LCC-analys av en elmotordrift
Kandidat-uppsats, Högskolan i Gävle/ElektronikSammanfattning : AFRY är ett ingenjörsföretag som har efterfrågat en studie som går ut på att ur ett elkonstruktionsperspektiv hitta enklare åtgärder för att bespara industrier pengar ge-nom att utföra energieffektiva investeringar i kontinuerliga elmotordrifter. Detta är extra relevant idag då energikostnaderna ökat anmärkningsvärt de senaste åren. LÄS MER
3. Drivsystem med låg övertonshalt - baserat på aktiva filter
Kandidat-uppsats, Lunds universitet/Industriell elektroteknik och automationSammanfattning : This thesis was conducted on CG Drives & Automation (Emotron), a company that invests in developing products and solutions to control and monitor electrical motors. One of their more popular product is the effective and energy saving Variable Frequency Drive (VFD). LÄS MER
4. Power cables in battery electric vehicles used in underground mining : Analysis of electromagnetic dynamics in high-power cables and development of application-specific design strategies for reduction of EMI
Master-uppsats, Uppsala universitet/ElektricitetsläraSammanfattning : The electrification of the automotive industry is growing in popularity, considering the environmental impacts of the conventional diesel-powered automobile. However, from the electromagnetic compatibility (EMC) viewpoint, it is observed that the use of variable-frequency drives (VFD) and relatively high-power cables to propel electrical motors has led to a considerable rise in electromagnetic interference (EMI) within and outside the machine.
