Abstract
Disclosed herein is a PM type step motor used to move a camera or an optical pickup lens of media related equipment. The step motor has a stator unit including first and second stators which butt against and are coupled to each other and each have a bobbin and a yoke attached thereto. Terminal blocks of the first and second stators are spaced apart from each other when the first and second stators are coupled to each other, thus allowing an automatic winding operation using winding equipment to be easily performed. The step motor includes a bushing which has in a central portion thereof a through hole through which a rotating shaft passes and is a two-stage structure having a small outer diameter part and a large outer diameter part, thus allowing the stator unit, the rotating shaft and a casing unit to easily be arranged coaxially.
