Abstract
(EN) A rotation angle detection device that detects the rotation angle and rotation speed of a motor generator, by using a resolver, and improves the resolver detection accuracy during drive operation of the motor generator by increasing the amplitude or frequency of an excitation signal. In addition the rotation angle detection device is configured such that, as a result of reducing the amplitude or frequency of the excitation signal when the motor generator is not being drive operated: a resolver detection accuracy at which rotation speed information for the motor generator can be obtained is held; and the amount of heat generated by an excitation circuit and the resolver can be suppressed.
(FR) L'invention concerne un dispositif de détection d'angle de rotation qui détecte l'angle de rotation et la vitesse de rotation d'un moteur-générateur, à l'aide d'un résolveur, et améliore la précision de détection du résolveur pendant une opération d'entraînement du moteur-générateur par l'augmentation de l'amplitude ou de la fréquence d'un signal d'excitation. En outre, en résultat à la réduction de l'amplitude ou de la fréquence du signal d'excitation lorsque le moteur-générateur n'est pas en train d'être entraîné, le dispositif de détection d'angle de rotation est conçu de telle sorte que : une précision de détection du résolveur à laquelle des informations de vitesse de rotation pour le moteur-générateur peuvent être obtenues soit maintenue ; et la quantité de chaleur dégagée par un circuit d'excitation et le résolveur puisse être supprimée.
