摘要： An electromotive drive device for a floatable device includes an electric motor operable by means of a separate power supply module with an energy accumulator, an electronic open-loop/closed-loop control unit and a remote control. The electric motor is within a housing connected to a drive propeller, which at least partially is surrounded by a protective device connected to the housing via connecting supports. The housing has an upper housing part and a lower housing part connected to each other by at least one releasable connection. The housing includes an elliptical bow, the end thereof transitioning into an essentially circular diameter with relative dimensions being a sum larger than an end of the housing with a projection opposite the bow. The housing in the lateral area behind the diameter is provided with intake openings for cooling water to flow inward. The cooling water can exit via outlet openings provided in the connecting supports. An operating method for the drive device includes an electronic open-loop/closed-loop control unit with an information processing unit. The drive ensures energetic use of the power supply module by reducing power while considering a travelled distance or travel time of the floatable device.
