POLSPOLE FOR ROTERANDE MAGNETISERINGSLINDNINGAR I ELEKTRISKA SYNKRONMASKINER

摘要

A pole coil wherein improved heat transfer at cooling fins thereof is achieved and includes cooling fins which are subdivided in the longitudinal direction into short portions which are bent out so that they are disaligned with each other. The pole coil is suitable for electrical machines and apparatus and especially for the revolving excitation windings of synchronous electric machines.
