An armature of a linear motor includes a plurality of first magnetic teeth and a plurality of second magnetic teeth, each of the magnetic teeth being formed by laminating multiple tooth elements made of electromagnetic steel sheets. The first magnetic teeth are arranged side by side in a linear form while the second magnetic teeth are located one each between the successive first magnetic teeth. Each of the second magnetic teeth interconnects the two adjacent first magnetic teeth located on both sides.

An armature of a rotating electric machine has a plurality of first magnetic teeth arranged side by side along a circumferential direction of the rotating electric machine and a plurality of second magnetic teeth joined to the first magnetic teeth. A pair of joint portions is formed at both end surfaces of a yoke portion of each first magnetic tooth, the joint portions formed at the facing end surfaces of the yoke portions of each successive pair of adjacent first magnetic teeth together forming a connecting part, whereas a mating part is formed at an outer end surface of each second magnetic tooth. Each second magnetic tooth is inserted between the adjacent first magnetic teeth along an axial direction of the rotating electric machine with the mating part fitted on the connecting part to interconnect the adjacent first magnetic teeth.
