Stationäre Trainingsvorrichtung nach Anspruch 5 oder 6, bei der der Generator Magnete und einen Satz von Spulen zum Produzieren einer n-Phasen-Wechselstrom-Energie verwendet, wobei die Detektionsvorrichtung den Nulldurchgang jeder der Phasen detektiert, so dass die Zeitintervalle zwischen dem Nulldurchgang bestimmt werden können, in denen jeweils das Schwungrad um einen vorbestimmten Winkel versetzt wird.
  8. Stationäre Trainingsvorrichtung nach Anspruch 7, bei der die Detektionsvorrichtung eine Rechteckwelle produziert, wenn der Nulldurchgang einer der Phasen detektiert wird, und wobei die Detektionsvorrichtung die Zeit der ansteigenden und/oder abfallenden Flanke jedes Impulses erfasst, um die Zeitintervalle zwischen den Flanken jedes Impulses zu bestimmen.
  9. Stationäre Trainingsvorrichtung nach einem der Ansprüche 1 bis 8, bei der die Steuervorrichtung das Drehmoment der Bremsanordnung voreinstellt, wobei das Drehmoment an dem Antriebsrad oder ein Wert, der von dem Drehmoment an dem Antriebsrad abhängig ist, in Abhängigkeit von den Zeitintervallen, den Zeitdifferenzen zwischen mindestens zwei der Zeitintervalle und dem Drehmoment der Bremsanordnung bestimmt wird.
  10. Verfahren zum Messen eines Drehmoments an einem Antriebsrad (16) oder eines Werts, der von dem Drehmoment an dem Antriebsrad einer Trainingsvorrichtung (1) abhängig ist, die eine Antriebsanordnung (2) mit dem Antriebsrad, das sich um eine Antriebsachse (3) dreht, eine erste und eine zweite Kurbel (4, 6), die jeweils mit dem Antriebsrad verbunden sind, und zwei Pedale (8, 10), die jeweils mit einer der Kurbeln verbunden sind, ein Schwungrad (14), das mittels mindestens eines Getriebemechanismus (12) mit der Antriebsanordnung verbunden ist, eine Bremsanordnung (18) zum Aufbringen einer Bremskraft auf das Schwungrad und mindestens eine Messvorrichtung (7) zum Messen der Position der ersten und der zweiten Kurbel aufweist, wobei das Verfahren folgende Schritte umfasst:
    Detektieren mehrerer Zeitintervalle mittels einer Detektionsvorrichtung (5), wobei in den Zeitintervallen jeweils das Schwungrad um einen vorbestimmten Winkel versetzt wird, wobei ferner die Zeitdifferenzen zwischen mindestens zwei der Zeitintervalle detektiert werden,
    Bestimmen in Abhängigkeit von den Zeitdifferenzen zwischen mindestens zwei Zeitintervallen des Drehmoments an dem Antriebsrad oder des von dem Drehmoment an dem Antriebsrad abhängigen Werts.
  11. Verfahren nach Anspruch 10, bei dem das bestimmte Drehmoment an dem Antriebsrad oder der von dem Drehmoment an dem Antriebsrad abhängige Wert mit der ersten oder der zweiten Kurbel in Abhängigkeit von der Position der ersten und der zweiten Kurbel korreliert wird.
  12. Verfahren nach Anspruch 10 oder 11, bei dem das Drehmoment an dem Antriebsrad oder der von dem Drehmoment an dem Antriebsrad abhängige Wert, das/der mit der ersten Kurbel korreliert ist, und das Drehmoment an dem Antriebsrad oder der von dem Drehmoment an dem Antriebsrad abhängige Wert, das/der mit der zweiten Kurbel korreliert ist, auf einem Display gezeigt wird, so dass die Differenz zwischen dem Drehmoment an dem Antriebsrad, das mit der ersten Kurbel korreliert ist, und dem Drehmoment an dem Antriebsrad, das mit der zweiten Kurbel korreliert ist, zu sehen ist.
  13. Verfahren nach einem der Ansprüche 10 bis 12, bei dem die Bremsanordnung einen Generator aufweist, der eine n-Phasen-Wechselstrom-Energie produziert, wobei der Nulldurchgang jeder der Phasen detektiert wird, so dass die Zeitintervalle zwischen dem Nulldurchgang bestimmt werden können, in denen jeweils das Schwungrad um einen vorbestimmten Winkel versetzt wird.
  14. Verfahren nach einem der Ansprüche 10 bis 13, bei der eine Rechteckwelle produziert wird, wenn der Nulldurchgang einer der Phasen detektiert wird, und wobei die Zeit der ansteigenden Flanke jedes Impulses erfasst wird, um die Zeitintervalle zwischen den Flanken jedes Impulses zu bestimmen.
  15. Verfahren nach einem der Ansprüche 10 bis 14, bei dem das Drehmoment der Bremsanordnung voreinstellt wird, wobei das Drehmoment an dem Antriebsrad oder der Wert, der von dem Drehmoment an dem Antriebsrad abhängig ist, anhand der Zeitdifferenzen zwischen mindestens zwei der Zeitintervalle und dem Drehmoment der Bremsanordnung bestimmt wird.
