Low-Speed Large-Capacity Electrical Machines
Abstract
Foreign publications on large-capacity low-speed electrical machines (up to 30 MW, 300 min-1) are reviewed. The design features of the propulsion electric motors for submarines and surface ships, as well as of the wind generators of terrestrial and marine windmills are shown. Induction and synchronous motors with a capacity of higher than 1 MW have expelled DC motors in the propeller electric drive systems. Gearless electric drives have found wide use in the electric propulsion systems of ships and submarines, and also in wind power engineering applications. In its final part, the article briefly outlines the main structural and technological features of designing large-capacity low-speed electrical machines.
