| Abstract |
In windpower pitch drives up to three motors have to be controlled with very accurate speed and
angular synchronism under varying load conditions. In the paper a very cost-effective solution is
proposed with three PM motors connected to one frequency converter. A new field-oriented like
control principle is outlined, ensuring the desired synchronism and avoiding motor pull-out in all
operating modes and at unsymmetrical load. |
