Abstract
A linear synchronous motor is provided, of which a core unit may readily be manufactured. Accordingly, the manufacturing cost of the linear synchronous motor may be reduced, and the weight of the linear synchronous motor may be lightened. The linear synchronous motor includes a frame member that is formed of a magnetic conductive material and surrounds the periphery of a core unit centering on a shaft. The frame member functions as a yoke that magnetically connects a plurality of magnetic pole portions. The frame member is constituted from a first divided frame member and a second divided frame member fixed to the core unit with screws.
