Abstract: The object of the invention is a cooling arrangement for an electrical machine in which a main magnetic field affects the stator and the rotor. In the arrangement, an auxiliary rotor (16, 16') is fitted onto the same shaft (8) with the rotor (6) of the machine and arranged to rotate in relation to the stator (4) and drive shaft (8) of the electrical machine. The number of poles in the auxiliary rotor (16, 16') is substantially smaller than the number of poles in the electrical machine, and a subharmonic magnetic field induced on the stator (6) of the electrical machine is arranged to rotate the auxiliary rotor (16, 16') and a fan (20) arranged to it.

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.
