Maszyny Elektryczne : zeszyty problemowe

2009

Nr 83

Research and Development Centre of Electrical Machines (BOBRME) KOMEL areas of interest include design, construction, lab and on-site tests and diagnostics of different kinds of electrical machines. At present we mostly deal with medium and large power induction machines and machines excited with permanent magnets. Komel occupies the leading position among Polish companies developing and investigating these machines. Therefore, this paper’s subject matter is limited to these two machine types. With respect to induction machines, the following topics have been covered: - motors with frequent start-ups, - motors with allowable long start-up time, - motors with decreased power losses (energy-saving motors), including those fulfilling NEMA MGI standards demands, - 6-phase motor adapted to inverter supply. Examples of different constructions have been presented, such as motors driving deep-well pumps, electric traction motors, sea motors, mine motors, high-speed motors, slip-ring motors with hollow shaft used for pipe cementing. With respect to electrical machines excited with permanent magnets, the following topics have been covered: - motors used for driving electric vehicles such as SAM, ELIPSA, QUAD, mine locomotive, motor hangglider, - synchronous generators for wind and hydro power stations.
