Abstract

The motor drives one or more ventilators. Two coils for different numbers of rotations are arranged in the stator such that if one coil fails and the other coil is switched over, the coils are not electrically affected. Preferably, the coils are 2/4 pole and are electrically separated. Instead of the usual two motors, one motor can be used. The motor may be provided with a ventilator wheel or with two such wheels left and right of the motor.

Description

Motor zum Antrieb eines, oder mehrerer Tiefgaragen­ ventilatoren, bei dem 2 Wicklungen für verschiedene Drehzahlen so im Stator untergebracht sind, daß sie sich bei Ausfall einer Wicklung und Umschal­ tung auf die andere Wicklung elektrisch nicht be­ einflussen können.Motor to drive one or more underground garages fans, in which 2 windings for different Speeds are housed in the stator that they fail in the event of a winding and shawl failure not electrically applied to the other winding can influence.

Bisher war es bei Tiefgaragen-Lüftungen Vorschrift, daß immer 2 Ventilatoren, die von 2 Motoren ange­ trieben werden, die gesamte erforderliche Luftmenge bringen müssen. Fällt ein Ventilator aus, muß der verbleibende Ventilator immer noch 60% der Luft­ menge bringen (Abb. 1).So far, it was a requirement for underground garage ventilation systems that always 2 fans, which are driven by 2 motors, must bring the total amount of air required. If one fan fails, the remaining fan must still bring in 60% of the air volume ( Fig. 1).

Es wird hier ein Motor beschrieben, bei dem die Betriebs-Wicklung 2-pol., also 3000 U/min. und die zweite Wicklung 4-pol., also 1500 U/min. ist. Beide Wicklungen sind elektrisch getrennt und gut gegeneinander isoliert, und können sich bei diesem Polzahlverhältnis, selbst bei einem Windungs- oder Körperschluß, gegenseitig nicht beeinflussen.An engine is described here in which the Operating winding, 2-pole, i.e. 3000 rpm. and the second winding 4-pin, i.e. 1500 rpm. is. Both windings are electrically isolated and good isolated from each other, and can look at this Pole ratio, even with a winding or Body closure, do not influence each other.

Üblicherweise liegt die 2-pol. Wicklung am Nutgrund und die 4-pol. Wicklung, wegen der Streuverluste, an der Nutöffnung.Usually the 2-pin. Winding at the bottom of the slot and the 4-pin. Winding, because of the wastage, at the slot opening.

Beide Wicklungen sind mit Thermokontakten versehen, sodaß eine gegenseitige Erwärmung der Wicklungen nicht entstehen kann (Abb. 4).Both windings are provided with thermal contacts so that the windings cannot heat up ( Fig. 4).

Der Motor ist so ausgelegt, daß er einen bestimmten Leistungsbereich abdeckt und durch Leistungsrege­ lung auf den erforderlichen Volumenstrom eingestellt werden kann. Der Läufer des Motors ist ein Wider­ standsläufer, um eine bessere Regelung der Drehzahl zu gewährleisten.The engine is designed to have a specific one Performance range and through performance set to the required volume flow can be. The runner of the motor is an opponent stance runner to better control the speed to guarantee.

Der Motor hat rechts und links einen Wellenstumpf, auf dem die Lüfterräder angebracht werden können.The engine has a stub on the right and left, on which the fan wheels can be attached.

Claims (5)
