Patent number: 10189552Abstract: A ship propulsion device (1) is adapted to rotate a propeller (20) to propel a ship (2). In a case where the rotating speed of the propeller (20) is less than a predetermined rotating speed, a low-output sub-motor (M2) is controlled and rotationally driven by a small-capacity general-purpose inverter (24), and the rotational driving is transmitted to the propeller (20) so as to rotate the propeller. In that case, in a drive system of a main motor (M1), rotation is not transmitted to a slip clutch (23) or an input shaft (7) by cutting off an on-off clutch (8). In a case where the rotating speed of the propeller (20) becomes equal to or more than the predetermined rotating speed, a driving source is switched from the sub-motor (M2) to the main motor (M1) so as to couple the on-off clutch (8), and the rotating speed of the main motor (M1) is controlled by the slip clutch (23) and transmitted to the propeller (20) so as to rotate the propeller (20).Type: GrantFiled: September 29, 2015Date of Patent: January 29, 2019Assignee: NIIGATA POWER SYSTEMS CO., LTD.Inventors: Koichi Shiraishi, Takuro Hatamoto, Masanori Kodera
