FIELD WINDING FOR STRAND-WOUND SALIENT POLE TYPE SYNCHRONOUS MACHINE

摘要

PURPOSE:To prevent springing-out to the outside of a field winding of a cooling fin by centrifugal force by a method wherein the cooling fin composed of a slender support plate and a plat overhung in the rectangular direction to the support plate, a strand is wound on the outside diameter side of the support plate and the field winding is constituted while the cooling fin is fixed to a pole core by the field winding. CONSTITUTION:A cooling fin 4 has plates 4a on both sides in the rectangular direction while holding a support plate 4b, and is formed in a U-shaped cross section, the support plate 4b is brought into contact with the pole insulation 5 of a pole core 1, and the cooling fin 4 is fixed by a field winding 3 constituted by winding a strand on the outside diameter side of the support plate 4b. The cooling fins 4 are installed on both left and right sides of the pole core 1. Accordingly, there is no possibility, in which the cooling fins 4 are sprung out by centrifugal force with rotation.
