Die elektrischen Kennwerte gewährleisten einen hohen Wirkungsgrad bei sehr breitem Luftspalt, wodurch das Geräusch und die auf den Anschlag wirkenden Kräfte verringert werden.The electrical parameters ensure high efficiency with a very wide air gap, which reduces the noise and the forces acting on the stop are reduced.
Aus der Figur ersieht man, dass der als Anschlag ausgebildete Ring bei der Drehbewegung hinter dem Laufrad angeordnet ist. Der Druck auf den Anschlag wird dabei durch Gegendruck der Puape ausgeglichen.From the figure it can be seen that the trained as a stop Ring is arranged behind the impeller during the rotary movement. The pressure on the stop is created by the counter pressure of the Puape balanced.
