PROBLEM TO BE SOLVED: To provide a motor assist system and a cargo handling assist device using the same which can immediately start work without requiring origin search at the time of restart after turning off power or after power outage and is inexpensive and excellent in maintainability.SOLUTION: A motor assist system comprises: a motor having a rotary output shaft on a load side; a motor rotational position detection unit for outputting a motor rotational position of the motor on an anti-load side of the motor as a motor rotational position signal in a range of 0 degree to 360 degrees; a load operation position detection unit with a variable passive element for outputting a finite operation position of a load connected to the rotational output shaft over a whole operation range of the load as a load operation position signal; a torque detection unit for outputting torque applied to the rotary output shaft as a torque signal; and a control circuit unit for transmitting a command signal for assisting an operation of the load to the motor on the basis of the motor rotational position signal, the torque signal, and the load operation position signal.SELECTED DRAWING: Figure 3
【課題】電源を切った後や停電後の再起動時に原点サーチが不要で即時作業を開始でき、安価でメンテナンス性にも優れたモータ助力システム及びこれを用いた荷役助力装置を提供する。【解決手段】負荷側に回転出力軸を有するモータと、モータの反負荷側にてモータのモータ回転位置を0度から360度の範囲でモータ回転位置信号として出力するモータ回転位置検出部と、可変受動素子を有して回転出力軸に繋がる負荷の有限の作動位置を負荷の作動範囲全域に渡って負荷作動位置信号にて出力する負荷作動位置検出部と、回転出力軸に加わるトルクをトルク信号にて出力するトルク検出部と、モータ回転位置信号、トルク信号及び負荷作動位置信号を基に負荷の作動を助力する指令信号をモータに送信する制御回路部と、を備える。【選択図】図3
