Connectors ( 25 a), ( 25 b), ( 25 c), ( 25 d), ( 25 e), and ( 25 f) for electrically connecting lead wires of armature windings ( 4 ) coiled around armature blocks ( 10 ), ( 11 ), and ( 12 ) are provided at respective ends of a plurality of the armature blocks ( 10 ), ( 11 ), and ( 12 ) such that connections of the armature windings ( 4 ) in the respective armature blocks become parallel connections. The connector pair including the connectors ( 25 b), ( 25 c) and the connector pair including the connectors ( 25 d), ( 25 e), which are provided between the armature blocks, are embodied as in-phase connections. On condition that the number of phases of the armature winding is taken as three and a magnetic pole pitch of a magnetic field is taken as taup, the armature blocks are spaced apart from each other at intervals of 2/3 taup. As a result, there can be obtained an armature of a linear motor and a linear motor, which can facilitate processing of lead wires of the armature windings and make the operation for assembling the armature blocks efficient and which enable an attempt to increase the thrust of the motor in accordance with an increase in the stroke of the movable element.
