Title:
ELECTRICAL DRIVE MECHANISM FOR SHIPS
Document Type and Number:
WIPO Patent Application WO1999036312
Kind Code:
A3
Abstract:
Disclosed is an electrical drive mechanism for ships, comprising a housing (1) arranged like a pod on the underside of the ship's hull to accommodate an electric motor with a rotor (3) and a stator (2) and at least one propeller (9) disposed on the shaft bearing the rotor. In order to improve the effective propulsion of said electrical drive mechanism for ships, the electric motor is designed as a synchronous permanent magnet motor, wherein the rotor (3) has permanent magnets (1) to excite the stator and the housing (1) is embodied as a radiator forming an external wall. Additional cooling devices (13, 14) can be arranged inside the housing (1). The housing (1) and the shaft (4) can be made of a light metal, especially an aluminium alloy.
