Bürstenloser gleichstrommotor

Номер: WO2016193031A1
Автор: Dirk Joachimsmeyer, Maxim Kronewald
Принадлежит: BROSE FAHRZEUGTEILE GMBH & CO. KOMMANDITGESELLSCHAFT

Ein bürstenloser Gleichstrommotor umfasst einen Stator, der eine Mehrzahl von Ankerspulen aufweist, und einen um eine Drehachse zum Stator drehbaren, permanenterregten Rotor, der zumindest zwei ungleichnamige Permanentmagnetpole aufweist, die ein durch einen Erregerfeldvektor beschreibbares Erregerfeld erzeugen. Eine Steuereinrichtung dient zum Ansteuern der Ankerspulen zum Erzeugen eines um die Drehachse an dem Stator umlaufenden, durch einen Ankerfeldvektor beschreibbaren Ankerfelds, wobei die Steuereinrichtung ausgebildet ist, im Betrieb des Gleichstrommotors die Ankerspulen so anzusteuern, dass sich ein Winkel zwischen dem Ankerfeldvektor und dem Erregerfeldvektor einstellt. Dabei ist vorgesehen, dass die Steuereinrichtung (2) eine ein Kennfeld (K) speichernde Speichereinheit (20) aufweist, wobei in dem Kennfeld (K) Winkelparameter (O) enthalten sind und die Steuereirichtung (2) ausgebildet ist, anhand des Kennfelds (K) den Winkel (α) zwischen dem Ankerfeldvektor (A) und dem Erregerfeldvektor (E) in Abhängigkeit von der Drehzahl (n) und dem Drehmoment (M) des Rotors (11) im Betrieb zu regeln. Auf diese Weise wird ein bürstenloser Gleichstrommotor zur Verfügung gestellt, der eine Optimierung des Betriebsverhaltens des Motors im Betrieb hinsichtlich unterschiedlicher Kriterien, insbesondere hinsichtlich der Effizienz, des Geräuschverhaltens und der elektromagnetischen Abstrahlung ermöglicht, dabei aber variabel durch einen Nutzer angepasst werden kann.

Die Erfindung betrifft die Absicherung eines Hochvoltnetzes, welches von einer elektrischen Energiequelle, wie zum Beispiel einer Traktionsbatterie eines Elektrofahrzeugs gespeist wird. Hierzu ist es vorgesehen, in einem Überwachungsstromkreis, wie zum Beispiel einem Hochvolt-Interlock, ein oder mehrere zusätzliche Temperatursicherungen anzuordnen, welche beim Überschreiten einer Temperatur den Überwachungsstromkreis unterbrechen und somit eine Trennung zwischen dem Hochvoltnetz und der speisenden Hochvoltbatterie initiieren.
