Abstract: A linear head module includes a plurality of linear units each having an output member, and a housing. The linear unit has a mover and a stator. The stator has an output-side bearing holder and a counter-output-side bearing holder. The housing has: a main body portion integrally including an output-side surface portion, a counter-output-side surface portion, and a coupling portion that couples the output-side surface portion and the counter-output-side surface portion; a flange facing the output-side surface portion; and a bracket facing the counter-output-side surface portion.

Abstract: A linear head module includes: a plurality of linear motors each including a mover having an output shaft portion; a plurality of detection portions each configured to detect a position of the respective output shaft portion in a direction of a thrust axis; a single circuit board provided with the plurality of detection portions; and a detected portion provided to the respective mover, the detected portion is fixed to the mover via a mounting base, and as viewed in the direction of the thrust axis, a direction in which the mounting base extends from the output shaft portion is different from a direction in which the output shaft portion and the circuit board face each other.

Abstract: A linear motor includes: a mover including an output shaft portion extending in a direction of a thrust axis; a detection portion configured to be capable of detecting a position of the output shaft portion in the direction of the thrust axis; and a detected portion fixed to the mover, the mover further includes: a mounting base to which the detected portion is attached; and a metal fastening member that fastens the mounting base to an end surface, on one side in the direction of the thrust axis, of the output shaft portion, and the mounting base includes: a metal fastened portion sandwiched between the end surface, on the one side in the direction of the thrust axis, of the output shaft portion, and the fastening member; and a resin mounting portion having a mounting surface to which the detected portion is attached, the mounting surface being provided at a position off the thrust axis.
