AbstractModern electric motors for road electric vehicles (automobiles, scooters, bicycles), light rail transit (street cars, trolley lines, subway trains), guided transit systems and elevators have been discussed. The paper aims at various types of rotary brushless motors, direct electromechanical drives and practical solutions to light traction systems. Modern permanent magnet (PM) motor technologies offer diversity of cutting-edge technology brushless motors, i.e., motors with one slot coil pitch windings, transverse flux motors, coreless disc type motors and PM assisted synchronous reluctance motors. There is a wide interest in liquid cooled traction motors and inverters as those apparatus minimize the volume of electromechanical drive systems and increase their power density. Frequently, the traction motor for road vehicles is integrated with a solid state converter. Light traction with linear motors has not been considered. Although induction motors are the most popular motors, PM brushless motors are more efficient, more compact, have better steady-state and dynamic performance at low speeds and are excellent motors for direct drive traction application.Key Words: electric motorspropulsiondriveslight tractionelectric vehicleselevators Additional informationNotes on contributorsJacek F. GierasJacek F. Gieras graduated in 1971 from the Technical University of Lodz, Poland. He received his PhD degree in Electrical Engineering (Electrical Machines) in 1975 and Dr hab. degree (corresponding to DSc), also in Electrical Engineering, in 1980 from the University of Technology, Poznan, Poland. From 1971 to 1998 he pursued his academic career at several Universities worldwide including Poland, Canada, Jordan and South Africa. He was also a Central Japan Railway Company Visiting Professor (Endowed Chair in Transportation Systems Engineering) at the University of Tokyo, Japan, Guest Professor at Chungbuk National University, Choengju, South Koreea, and Visiting Professor at the University of Rome La Sapienza, Italy. In 1987 he was promoted to the rank of Full Professor (life title given by the President of the Republic of Poland). Since 1998 he has been involved in high technology research in Connecticut, U.S.A. Prof. Gieras authored and co-authored 7 books, over 200 scientific and technical papers and 10 patents. His most important books are: "Linear Induction Motors", Oxford University Press, 1994, U.K., "Permanent Magnet Motors Technology: Design and Applications", Marcel Dekker Inc., New York, 1996, second edition 2002, (co-author M. Wing) and "Linear Synchronous Motors: Transportation and Automation Systems", CRC Press LLC, Boca Raton, Florida, 1999 . Prof. Gieras is a Fellow of IEEE, U.S.A., and members of steering committees of numerous international conferences and symposia.Nicola BianchiNicola Bianchi received the Laurea and Ph.D. degree in Electrical Engineering from the University of Padova in 1991 and 1995 respectively. Since 1998, he has worked at the Department of Electrical Engineering, University of Padova, as a senior research assistant in the Electric Drives Laboratory. His interest is in the field of the electromechanical design of brushless, synchronous and induction motors with particular interest to the drives applications. Dr. Bianchi authored and co-authored 2 books, and several scientific and technical papers and 2 patents.
