Abstract

Since 2009 she has been with Konecranes, Finland. Her research interests include electrical machines and drives, energy-efficiency design, and hybridization. Juho Montonen was born in 1988 in Joutseno, Finland. He received the Master of Science (M.Sc.) degree from Lappeenranta University of Technology (LUT), Finland in 2012 and Bachelor of Science (B.Sc.) in 2011. He is currently doctoral student in LUT. He is doing the research concerning about electrical machines and drives. His research work focuses on permanent magnet motors, especially those which are used in different kinds of traction applications. Vitaliy Sizonenko was born in 1989 in Tomilino, Russia, received the Master of Science (M.Sc.) degree from Moscow Power Engineering Institute (MPEI), Russia and from Lappeenranta University of Technology (LUT), Finland in 2012 (double degree programme), the Bachelor of Science (B.Sc.) degree from MPEI in 2010. Pia Lindh received the D.Sc. (Tech.) degree in 2004 from Lappeenranta University of Technology. She currently works as a researcher teacher at the Department of Electrical Engineering. Her research interests include a wide range of electrical machines and drives, permanent-magnet machines and traction applications in particular. Juha Pyrhönen, a Member of IEEE, was born in 1957 in Kuusankoski, Finland, received the Doctor of Science (D.Sc.) degree from Lappeenranta University of Technology (LUT), Finland in 1991.

He is currently the Head of the Department of Electrical Engineering, where he is engaged in research and development of electric motors and electric drives.His current interests include different synchronous machines and drives, induction motors and drives and solid-rotor high-speed induction machines and drives.

Design and Analysis of a High Temperature Particulate Hoist for Proposed Particle Heating Concentrator Solar Power Systems

“…Motor selection is an important consideration and several informative publications discuss the selection and analysis of hoist motors such as for example [25], [26], [27], [28] and [29]. Development of advanced motor designs such as the doubly-fed induction motor [28], which promises enhanced overall efficiency and other advantages in hoist applications, is of special interest.…”

Energy consumption and energy efficiency improvement of overhead crane’s mechanisms

“…Parallel to the energy saving systems, scientists have investigated other field of energy savings. The article [18] focuses on the energetic efficiency of hoisting mechanisms in industrial applications. A typical duty cycle of the hoist is periodically intermittent.…”

“…When a sequential run with constant load takes place, the hoisting mechanism has to be driven by motors designed for S3 duty cycle [12]. Authors of paper [18] investigate the influence of motor's rotor material on the energetic efficiency for a few stack lengths. The conclusion is that because of low operating hours and major share of partial loads, increasing efficiency does not provide notable energy or cost savings.…”

Energy consumption and overloads of crane hoisting mechanism with system of reducing operational loads

“…In mechanical Some teams conducted a research of energetic efficiency of motors which were used in hoisting mechanisms fed by inverters. The research presented in [12] showed, that increasing the energetic effectiveness of motors did not make tangible benefits. It was caused by short times of operation and a large share of partial load of the mechanism.…”
