Marine battery driven motor

A motor assembly for providing propulsion of a floating vessel comprising:

• a motor device wherein the motor device comprises:
• an electrical motor,
• a propeller arranged inside a propeller house,
• a rotatable arm, and
• a battery and controlling unit, and
• a mount for attaching the motor device to the floating vessel,
• wherein:
• the motor device is detachably mounted to the mount,
• the propeller house is connected to the rotatable arm, and
• the rotatable arm connects the propeller house to the battery and controlling unit,
• a controlling logic for motor control is provided and arranged inside the rotatable arm and electrically connected to the battery and controlling unit on one side and to the motor device on the other side, and
• the motor device further comprise:
• a first active position in which the propeller housing is arranged under the floating vessel, and
• a second inactive position in which the propeller housing is arranged in a resting position, and
• the rotatable arm is pivotally connected to the battery and controlling unit in a manner allowing a complete folding and unfolding of the rotatable arm between the first inactive position and the second inactive position, such that when the motor device is folded in the second inactive position the rotatable arm can be positioned in a generally parallel position relative the battery and controlling unit.
