Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 本発明は、ノイズの発生を防止でき、高価な スイッチング素子を用いずに、コストを低減できる船舶 の電気推進装置を提供することを目的とする。 【解決手段】 船舶の推進装置1に連結されて推進装置 1を回転駆動する推進用交流電動機8と、推進用交流電 動機8に給電する交流発電機13と、この発電機13に 連結されてこの発電機13を回転駆動する発電用原動機 14と、発電機13または発電用原動機14の回転数を 計測する電磁ピックアップ15と、電磁ピックアップ1 5により計測された回転数をフィードバック信号として 船舶の速度設定に相当する回転数に発電用原動機13の 回転数を制御するコントローラ24を備える。この構成 により、船舶の速度設定値に応じて発電用原動機14の 回転数が制御され、すなわち発電機13(給電ライン1 0)の周波数が制御され、推進用交流電動機8の回転数 が制御される。 (57) Abstract: An object of the present invention is to provide an electric propulsion device for a marine vessel that can prevent generation of noise and can reduce cost without using expensive switching elements. SOLUTION: A propulsion AC motor 8 which is connected to a propulsion device 1 of a ship and rotationally drives the propulsion device 1, an AC generator 13 which supplies power to the propulsion AC motor 8, and which is connected to the generator 13, A power generator 14 for rotating and driving the generator 13, an electromagnetic pickup 15 for measuring the rotation speed of the generator 13 or the power generator 14, and an electromagnetic pickup 1 And a controller 24 for controlling the rotation speed of the power generating motor 13 to a rotation speed corresponding to the speed setting of the ship using the rotation speed measured by 5 as a feedback signal. With this configuration, the number of revolutions of the power generating motor 14 is controlled according to the speed set value of the ship, that is, the power generator 13 (the power supply line 1). 0) is controlled, and the rotation speed of the propulsion AC motor 8 is controlled.
