Abstract

677,941. Machines with permanent magnets. BRITISH THOMSON-HOUSTON CO., Ltd. May 24, 1950 [June 1, 1949], No. 13043/50. Class 35. A permanent magnet rotor for a motor or generator has a radially polarized magnet surrounded by a laminated sleeve carrying a squirrel cage and has damping bars at the sides of the magnet in the inter-polar regions linked by conductive end-plates. As shown, the copper bars 6 are united to end-members 8 to form a loop about the magnet 4 and the assembly is surrounded by a ring carrying a squirrel cage of copper or aluminium. In the case of a fourpole magnet the bars 6 are replaced by four bars in the inter-polar recesses. Specifications 536,661 and 677,942 are referred to.
