PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Kühleinrichtung für Drehfeldmotoren, die mit einem besonderen Rotor zum Antrieb eines Ventilators versehen sind. Erfindungsgemäß wird der besondere Rotor durch das Streufeld der Spulenköpfe in Umlauf gesetzt. Es ist bekannt, besondere Rotoren, die lose drehbar auf der Ankerwelle angeordnet sind, durch das eigentliche Statorfeld in Umlauf zu setzen. DerThe invention relates to a cooling device for rotary field motors with a special Rotor for driving a fan are provided. According to the invention, the special The rotor set in rotation by the stray field of the coil heads. It is known, special rotors, which are loosely rotatably arranged on the armature shaft, through the actual To put stator field in circulation. Of the
ίο Motoranker ist dabei so viel verkürzt, daß er und der besondere Rotor innerhalb des Stators Platz finden. Durch die Erfindung wird dieser älteren Anordnung gegenüber erreicht, daß die Länge des Hauptrotors gleich der vollen Länge des Stators sein kann, das Statorfeld also unvermindert für den Antrieb des Hauptrotors ausgenutzt wird.ίο Motor anchor is shortened so much that it and the special rotor can be accommodated inside the stator. Through the invention this older arrangement achieved that the length of the main rotor equal to that can be the full length of the stator, so the stator field is undiminished for driving the Main rotor is used.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel im Längsschnitt, α ist der Hauptanker des Motors und δ ein Hohlkörper aus elektrisch gutleitendem Material, ζ. Β. aus Kupfer, der als besonderer Rotor dient. Der Hohlkörper δ ist auf der Achse i befestigt, die sich in dem Lager k drehen kann. Innerhalb des Hohlkörpers δ ist der magnetisch gutleitende Körper h angeordnet, der umlaufen, aber auch feststehen kann, g sind die Spulenköpfe des Stators c.The drawing illustrates an embodiment in longitudinal section, α is the main armature of the motor and δ is a hollow body made of electrically good conductive material, ζ. Β. made of copper, which serves as a special rotor. The hollow body δ is attached to the axis i , which can rotate in the bearing k. Inside the hollow body δ, the magnetically highly conductive body h is arranged, which revolves, but can also be stationary, g are the coil heads of the stator c.
Wenn der Stator vom Strom durchflossen wird, erzeugen die Spulenköpfe ein Streudrehfeld, durch welches in bekannter Weise Ströme in dem Hohlkörper δ induziert werden, wodurch dieser in Drehung versetzt wird.When the current flows through the stator, the coil ends generate a stray rotating field, by which currents are induced in the hollow body δ in a known manner, whereby this is set in rotation.
An Stelle des Hohlkörpers b kann auch ein Kurzschlußanker oder eine dicht über den Spulenköpfen gelagerte Scheibe als besonderer Rotor dienen. Statt des Eisenringes h können magnetisierbare Körper auch an anderer Stelle zur Verstärkung des auf den besonderen Rotor einwirkenden Feldes angeordnet werden.Instead of the hollow body b , a short-circuit armature or a disc mounted close to the coil heads can serve as a special rotor. Instead of the iron ring h , magnetizable bodies can also be arranged elsewhere to reinforce the field acting on the particular rotor.
Es ist möglich, an den einzelnen Spulengruppen des Stators Eisenkörper so anzubringen, daß dadurch die Polzahl des Feldes, in dem sich der besondere Rotor dreht, kleiner wird als die Polzahl des Stators. Man kann auf diese Weise erreichen, daß z. B. bei einem achtpoligen Motor der besondere Rotor in einem vier- oder achtpoligen Feld umläuft.It is possible to attach iron bodies to the individual coil groups of the stator in such a way that that thereby the number of poles in the field in which the particular rotor rotates is smaller is called the number of poles of the stator. One can achieve in this way that z. B. at one eight-pole motor, the special rotor rotates in a four- or eight-pole field.
