Abstract
Vielpoliger Gleichstrommotor mit Permanent- und Elektromagneten unterscheidet sich von existierenden Gleichstromelektromotoren mit Permanent- und Elektromagneten dadurch, dass dieser aus mehreren (2, 3, 4) zweipoligen (Nord-Süd) Permanentmagneten und Elektromagneten besteht.Multi-pole permanent magnet and electromagnet DC motor differs from existing DC and DC electric motors in that it consists of several (2, 3, 4) double pole (north-south) permanent magnets and electromagnets.
Description
Ein vielpoliger Gleichstromelektromotor mit Permanentmagneten ist anschaulich auf
Dieser Motor besteht aus vier Permanentmagneten (
Allgemein ist bekannt, dass alle Gleichstromelektromotoren mit Permanentmagneten einen Nachteil aufweisen – den geringen Wirkungsgrad.It is generally known that all DC electric motors with permanent magnets have a disadvantage - the low efficiency.
Bei Elektromotoren resultiert die Drehbewegung aus der Tatsache, dass sich gleichnamige Pole, beispielsweise Nord und Nord, sich abstoßen und ungleichnamige Pole, Nord und Süd, sich anziehen. Diese beiden entgegengesetzten Kräfte werden genutzt, um eine Drehbewegung zu erzeugen.In electric motors, the rotational movement results from the fact that poles of the same name, such as north and north, repel each other and poles of the same name, north and south, attract each other. These two opposing forces are used to create a rotational movement.
In
Die Ursache für dieses Phänomen sind die Eigenschaften der magnetischen Felder und der Aufbau der Magneten. Um den beschriebenen Nachteil zu beseitigen, müssen die Feldlinien des Permanentmagneten und des Elektromagneten in eine Richtung gerichtet sein. Um ein solches Magnetfeld zu erzeugen, kann ein bogenförmiger Magnet genutzt werden, wie in
Wenn zwei solcher bogenförmiger Magnete, wie in
Für einen effizienten Betrieb eines solchen Motors muss die rotierende Bewegung der einzelnen Module in die gleiche Richtung gerichtet sein. Diese Bedingung wird, wie im Folgenden beschrieben, erfüllt. Ein solcher Modul, wie bereits erwähnt, besteht aus zwei Elementen, einem Elektro- und einem Permanentmagneten, die, wie in
In
Der Elektromagnet besteht aus Elektrospulen mit metallischem Kern, die auf einer gemeinsamen Grundlage angebracht sind, wie in
