VENTILATING SYSTEM FOR ELECTRICAL ROTATING ELECTRICAL MACHINES EQUIPPED WITH A FORCED-FLUID FLOW COOLING DEVICE AND ROTATING ELECTRICAL MACHINE COMPRISING SAME

摘要

The invention concerns a ventilation system for a rotary electrical machine of the type comprising a rotor mounted so as to rotate in a stator and a device for cooling by forced flow of a cooling fluid, such as air, provided with at least one fan fixed to the rotor and an independent fan (10) disposed so as to be decisive for cooling at relatively low speeds of rotation of the rotor. The invention can be used for rotary electrical machines.
