Patent

CA 2480255

The present invention relates to a propeller drive arrangement for vessels used in water-borne traffic, and specifically to a propeller drive arrangement containing a propulsion unit, and to such an arrangement, which contains a propulsion unit, which is turnable relative the hull of the vessel. Particularly the present invention relates to a system and a method for braking a motor of a propulsion unit. The solution for braking the propulsion unit according to the present invention is based on short-circuiting a permanently magnetized motor.

La présente invention concerne un système de commande d'hélices de navires utilisés dans un trafic sur l'eau, et notamment d'un système de commande d'hélices comprenant une unité de propulsion, et un tel système comprenant une unité de propulsion qui tourne par rapport à la carène du navire. La présente invention concerne plus précisément un système et un procédé de freinage du moteur d'une unité de propulsion. La solution de freinage de l'unité de propulsion selon la présente invention est basée sur un court-circuitage d'un moteur à aimantation permanente.
