PROBLEM TO BE SOLVED: To uniformize shared loads of a plurality of AC servo motors of an electric turn control device.SOLUTION: A turn control device 2 which controls a freely turnable ship propulsion machine has: a turn control substrate 7 which calculates a digital motor speed instruction value from deviation between a signal from a sensor 6 which detects a turning position of the ship propulsion machine and a handle signal; and a plurality of AC servo amplifiers A1 and A2 which receive the motor speed instruction value from the turning control substrate, output motor speed command values, and drive AC servo motors M1 and M2. In the respective amplifiers, the motor speed command values are reduced according to load amounts when the motors are power running, the motor speed command values are increased according to the load amounts when the motors are regenerative, and the motor speed command values are not corrected when the load amount of the motors are equal to or less than a fixed value. The respective loads of a plurality of AC servo motors can be distributed to uniform values.SELECTED DRAWING: Figure 3
【課題】電気式旋回制御装置の複数のACサーボモータの分担負荷を均一化する。【解決手段】旋回自在である船舶推進機を制御する旋回制御装置2は、船舶推進機の旋回位置を検出するセンサ6からの信号と、ハンドル信号との偏差からデジタルのモータ速度指示値を演算する旋回制御基板7と、旋回制御基板からモータ速度指示値を受信してモータ速度指令値を出力し、ACサーボモータM1,M2 を駆動する複数のACサーボアンプA1,A2 を有する。各アンプでは、モータが力行の場合には負荷量に応じてモータ速度指令値を減少させ、回生の場合には負荷量に応じてモータ速度指令値を増大させ、モータの負荷量が一定値以下の場合には補正しない。複数ACサーボモータの各負荷を均一な値に分散できる。【選択図】図3
