Abstract
A propulsion system includes at least one permanent magnet motor, the magnet motor including an outer housing structure. In the housing structure, a stator and a rotor are arranged in such a way that a gap is formed between the stator and rotor, the stator being fixedly connected to the housing structure, whilst the rotor is connected to a motor shaft extending through the housing structure. A plurality of coils/windings are arranged around an inner circumference of the stator, whilst a plurality of permanent magnets are arranged around an outer circumference of the rotor. Through a coupling, the motor shaft is connected to a propeller shaft including a propeller. A thrust bearing and a propeller pitch control system are integrated into the permanent magnet motor.

A propulsion system for vessels comprising:
- at least one electric permanent magnet motor, which permanent magnet motor comprises
- a housing structure and
- a stator and rotor arranged therein, the rotor and the stator being separated by an air gap,
- a plurality of coils/windings arranged around the inner circumference of the stator and
- a plurality of permanent magnets arranged around the outer circumference of the rotor, the stator being fixedly connected to housing structure and the rotor being connected to a motor shaft extending through housing structure, which motor shaft is through a coupling further connected to a propeller shaft comprising a propeller, wherein a thrust bearing and an oil distributor unit are integrated into the electric permanent magnet motor.
