CA 2478820

An asymmetrical drive motor (150) and apparatus (100) with the asymmetric drive motor (150) driving a barrier (112). The asymmetric motor (150) drives the barrier (112) at different drive powers according to direction, time of travel, safety requirements or speed. The drive power is controlled by electrically changing the capacitance value for a permanent split capacitor motor (150).

L'invention concerne un moteur d'entraînement asymétrique ainsi qu'un appareil comprenant ce moteur et entraînant une barrière. Le moteur d'entraînement asymétrique entraîne la barrière avec différentes puissances selon la direction, le temps de déplacement, les besoins de sécurité ou la vitesse. La puissance d'entraînement est commandée par changement électrique de la valeur du condensateur d'un moteur à condensateur permanent.
