摘要： To provide a motor system that can control the position of a control object in multiple directions while suppressing the number of required switching elements. A motor system includes: a power conversion device including first, second, and third up-down arms each including two switching elements connected in series; a control object; and a first load including a magnetic pole tooth facing the control object, and a winding wound around the magnetic pole tooth. The motor system includes a second load including two magnetic pole teeth facing each other in a second direction with the control object therebetween, and a winding wound around one or both of the magnetic pole teeth. The power conversion device provides a force with respect to a first direction to the control object through an output to the first load, and provides a force with respect to the second direction to the control object through an output to the second load.
