‘Electromagnetic Gears’ are going to be improved in order to realize ‘Ideal Ship Propulsion Systems’ in view of energy saving and labour reduction in navigation. The electromagnetic gears which were devised by me fifteen years ago were developed between 1972 and 1975. An equipment of the rating 16 000 ps 430/107.5 rpm made on an experimental basis was tested on various items such as a load test, a starting test and so on, in the development of the electromagnetic gear.<BR>Any mechanical gears are not included in the original electromagnetic gears each of which is made of an electromagnetic coupling and a synchronous machine connected mechanically and electrically with each other. Each of improved electromagnetic gears described in this paper is made of an electromagnetic coupling, a rotating electric machine and a mechanical gear which are connected mechanically and electrically with each other.<BR>We can obtain the following effects of improved electromagnetic gears.<BR>(1) An electromagnetic gear can be inserted between a super-low speed propeller and a 2 cycle low speed diesel engine which is robust and reliable.<BR>(2) Exhaust heat energy of a diesel engine can be utilized enough and certainly.<BR>(3) Rotating speed and direction of a propeller can be controlled continuously by using an electromagnetic gear connected with 2 cycle diesel engine.<BR>In this paper, the possibility of realization of ideal ship propulsion systems by using the improved electromagnetic gears are explained on the basis of the test results of the before-mentioned development of 16 000 ps electromagnetic gear and of an experimental equipment of a small capacity of wound rotor induction motor.
