Abstract
Description
Die Erfindung betrifft einen Motorpositionssensor, insbesondere einen Motorpositionssensor, der die Veränderung des Drahtwicklungsaufbaus gestattet.The The invention relates to a motor position sensor, in particular a Motor position sensor, the change of the wire winding structure allowed.
Der
im Motor A in
Wie vorstehend beschrieben, muss der Hauptkörper P30 eines herkömmlichen Resolvers P10 im Zusammenwirken mit dem Transformator P20 induktiv betätigt werden. Folgende Probleme treten daher im praktischen Einsatz auf:
- 1. Wenn sich der Hauptkörperrotor P31 des Hauptkörpers P30 des Resolvers P10 mit dem Transformatorrotor P21 des Transformators P20 synchron umdrehen, erfolgt die Übertragung des Auslösesignals dazwischen über den elektrischen Anschluss. Der Kabelbruch tritt jedoch leicht während der Umdrehung des Hauptkörperrotors P31 des Hauptkörpers P30 und des Transformatorrotors P21 des Transformators P20 auf, der dazu führt, dass Signal verloren geht und der Resolver daher nicht mehr funktioniert.
- 2. Die Zentralspindel A1 des Motors A wird gleichzeitig den
Gewichten des Transformators P20 und des Hauptkörpers P30 des Resolvers
10 ausgesetzt, die ebenfalls eine Laufbelastung für die Zentralspindel A1 des Motors A verursacht. Bei langfristiger Umdrehung wird der Aufbau der Zentralspindel A1 durch die angestiegene Schwingung des Motors zerstört. Dies hat zur Folge, dass Motor A im Inneren beschädigt ist und dadurch hohe Reparaturkosten anfallen.
- 1. When the main body rotor P31 of the main body P30 of the resolver P10 rotates synchronously with the transformer rotor P21 of the transformer P20, the transmission of the trigger signal therebetween occurs via the electrical terminal. However, the cable break occurs easily during the revolution of the main body rotor P31 of the main body P30 and the transformer rotor P21 of the transformer P20, which causes signal to be lost and therefore the resolver does not function anymore.
- 2. The center spindle A1 of the motor A is simultaneously the weights of the transformer P20 and the main body P30 of the resolver
10 exposed, which also causes a running load for the central spindle A1 of the motor A. For long-term rotation of the structure of the central spindle A1 is destroyed by the increased vibration of the engine. This has the consequence that motor A is damaged inside and thereby incur high repair costs.
Der Erfindung liegt die Aufgabe zugrunde, einen Motorpositionssensor zu schaffen, welcher die Veränderung des Drahtwicklungsaufbaus gestattet.Of the Invention is based on the object, a motor position sensor to create what the change allowed the wire winding structure.
Diese Aufgabe wird erfindungsgemäß gelöst durch einen Motorpositionssensor, der die im Anspruch 1 angegebenen Merkmale aufweist. Weitere vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.These The object is achieved by a motor position sensor having the features specified in claim 1 having. Further advantageous developments of the invention are based the dependent claims out.
Gemäß der Erfindung weist ein Motorpositionssensor einen Resolver, mehrere Auslösespulen, mehrere Sinusspulen sowie mehrere Kosinusspulen auf. Der Resolver enthält einen Hauptkörper, der einen Hauptkörperrotor und einen Hauptkörperstator aufweist. Um den Hauptkörperrotor herum wird eine Vielzahl von magnetischen Rotorpolen zentral angeordnet und um den Hauptkörperstator herum wird eine Vielzahl von magnetischen Statorpolen zentral angeordnet, die den magnetischen Rotorpolen des Resolvers entsprechen. Auf die ungeraden magnetischen Statorpole des Hauptkörperstators werden jeweils eine Auslösespule und eine Sinusspule gewickelt, während eine Auslösespule und eine Kosinusspule jeweils auf die geraden magnetischen Statorpole des Hauptkörperstators gewickelt werden.According to the invention For example, one motor position sensor has one resolver, multiple trip coils, multiple Sinusoidal coils as well as several cosine coils. The resolver contains one Main body the one main body rotor and a main body stator. Around the main body rotor around a plurality of magnetic rotor poles is arranged centrally and around the main body stator around a plurality of magnetic stator poles is arranged centrally, which correspond to the magnetic rotor poles of the resolver. On the Odd magnetic stator poles of the main body stator are respectively a trip coil and a sine coil wound while a trip coil and a cosine coil on the straight magnetic stator poles, respectively of the main body stator be wrapped.
Außerdem werden die Auslösespulen gemäß der Erfindung auf dem Hauptkörperstator gewickelt, um die dauerhafte glatte Übertragung des Auslösesignals zu sichern, die gekoppelte Betätigung des Transformators herabzusetzen sowie die Bauteilkosten zu verringern. Um die Ziele zu erreichen, werden die Fertigungskosten eines erfindungsgemäßen Motorpositionssensors durch derartigen Spulenaufbau verringert, dass eine Auslösespule und eine Sinusspule auf die jeweiligen ungeraden magnetischen Statorpole des Hauptkörperstators oder eine Auslösespule und eine Kosinusspule auf die jeweiligen geraden magnetischen Statorpole des Hauptkörperstators gewickelt werden.In addition, will the trip coils according to the invention on the main body stator wrapped around the permanent smooth transmission of the trigger signal to secure the coupled operation of the Minimize transformer costs and reduce component costs. To achieve the goals, the manufacturing costs of a motor position sensor according to the invention by such a coil construction reduces that a trip coil and a sine coil on the respective odd magnetic stator poles of the main body stator or a trip coil and a cosine coil on the respective straight magnetic stator poles of the main body stator be wrapped.
Des Weiteren tragen die magnetischen Rotorpole des Hauptkörperrotors zu der weiteren Senkung der Fertigungskosten bei, indem sie keinen Spulenaufbau aufweisen. In diesem Fall ist nicht zu befürchten, dass die Übertragung des Auslösesignals von diesem Hauptkörperrotor beeinträchtigt wird. Außerdem können die Bauteilkosten durch die Reduzierung der gekoppelten Betätigung des Transformators verringert werden, der dem Resolver zum Festlegen des Anlaufswinkels durch Positionsermittelung eine geeignete Strommenge zuführt.Of Further carry the magnetic rotor poles of the main body rotor to further reduce manufacturing costs by eliminating a coil assembly exhibit. In this case, there is no fear that the transfer the trigger signal from this main body rotor is impaired. Furthermore can the component costs by reducing the coupled actuation of the Transformers are reduced, the resolver to set the starting angle by position detection a suitable amount of electricity supplies.
Ferner kann die Gewichtbelastung der Zentralspindel des Motors gemäß der Erfindung reduziert werden, um einen reibungslosen Lauf aufrechtzuerhalten und die Zuverlässigkeit des Motors relativ zu erhöhen. Um diese Aufgabe zu lösen, wird es beim erfindungsgemäßen Motorpositionssensor derart gestaltet, dass kein Transformator auf der Zentralspindel des Motors anzuordnen ist, der mit dem Resolver zusammenwirkt. Darüber hinaus liegt auf den magnetischen Rotorpolen des Hauptkörperrotors keine Spule vor, dies sorgt dafür, die Gewichtbelastung der Zentralspindel des Motors zu reduzieren und einen ausgewuchteten Lauf der Zentralspindel des Motors aufrechtzuerhalten. Dadurch kann die Lebensdauer verlängert und die Kostenbelastung durch die Ersparung der Reparaturkosten herabgesetzt werden.Furthermore, the weight load of the central spindle of the engine according to the invention can be reduced to maintain a smooth running and to increase the reliability of the engine relatively. To achieve this object, it is designed in the engine position sensor according to the invention such that no transformer is to be arranged on the central spindle of the motor, which cooperates with the resolver. In addition, there is no coil on the magnetic rotor poles of the main body rotor, this provides for reducing the weight load on the central spindle of the motor and maintaining a balanced running of the central spindle of the motor. This can extend the life and reduce the cost burden by saving on repair costs.
