Abstract
A linear motor includes an excitation unit including a shaft and a plurality of permanent magnets located in the shaft, and an armature including a plurality of coils surrounding the excitation unit and a magnetic cover covering the coils. The plurality of coils of the same phase group are continuously wound over a plurality of insulative bobbins. A tap conductor, a jumper wire between the coils, and a terminal wire of the coils in different phase groups that are continuously wound are separately disposed in different corner portions in the magnetic cover, and the terminal wire of each phase is connected to a circuit board.
