Abstract:
A cooling arrangement is disclosed for an electrical machine in which the main cooling air circulation within the machine is arranged using a centrifugal blower in at least one of the ends of the machine, making the main cooling air circulation flow through at least an air space in the machine and the outer surface of the stator. A circulating fan is arranged in the immediate vicinity of the centrifugal fan for the purpose of generating a coil end circulation that circulates air at least in the area of the machine's coil ends.
