The rotary electrical machinery which has the ventilation system, and this kind of device which are used for the rotary electrical machinery which has the device which is cooled by the forcing flow of the fluid

摘要

Topic Problem of high mechanical loss, and big ventilation noise where it is specific to the known system was cancelled, the ventilation system for the rotary electrical machinery is offered.SolutionsBeing the ventilation system for the rotary electrical machinery, at least one which is locked to the rotor and this rotor which are installed inside the stator fan, and the independent fan (10) it possesses, it has the cooling system which you force flow fluid such as air. This independent fan (10), in order to become the determinant of cooling at the rotary speed of the relatively low rotor, it is arranged. Selective figure Figure 2
