To provide a motor system capable of reducing a facility load by suppressing a starting current low, and capable of being exchanged in a short period when the motor system is in failure.SOLUTION: A driving source 4 making a load device 2 operate with a power from a power supply 3, includes: a first induction motor 6; a second induction motor 7; and an interlock part 8 that makes an input axis 2a of the load device 2 operate by combining an output of the first induction motor 6 and an output of the second induction motor 7. A control part 5 performs a starting control that controls the driving source 4 until a rating operation required for exciting a prescribed function in the load device 2, and the starting control includes a first induction motor operation control that makes the first induction motor 6 operate and a second induction motor operation control that makes the second induction motor 7 operate. After the start of the first induction motor operation control, the second induction motor operation control is started.SELECTED DRAWING: Figure 3 【課題】始動電流を低く抑えて設備負担を軽減することが可能であり、電動機が故障した場合等に短期間で交換することができる電動機システムを提供すること。【解決手段】電源３からの電力によって負荷機器２を作動させる駆動源４は、第一誘導電動機６と、第二誘導電動機７と、第一誘導電動機６の出力と第二誘導電動機７の出力とを合わせて負荷機器２の入力軸２ａを作動させる連動部８を有し、制御部５は、負荷機器２が所定の機能を発揮するのに必要な定格運転まで駆動源４を制御する始動制御を行い、始動制御には、第一誘導電動機６を運転させる第一誘導電動機運転制御と、第二誘導電動機７を運転させる第二誘導電動機運転制御とが含まれ、第一誘導電動機運転制御を開始した後に、第二誘導電動機運転制御を開始する。【選択図】図３
