Provided is a method for manufacturing a coil unit that is suited to the bulk manufacturing of multiple sets of coil parts for a multi-axis linear motor actuator. This method of manufacturing a coil unit for a multi-axis linear motor actuator, which is constituted by disposing multiple sets of linear shaft motors 10 in a line at a prescribed pitch, includes: a step in which a coil fixing member 50 is prepared that holds receiving parts 51 that are capable of receiving multiple coil parts 15, which are equal in quantity to the multiple sets of linear shaft motors, with the coil parts being arranged in a line at the prescribed pitch; a step in which the multiple coil parts are disposed by being arranged in a line and secured to the coil fixing member; and a step in which electromagnetic shielding plates 70 that are longer than the coil parts are disposed along a center axis direction at locations corresponding to the spaces between at least adjacent coil parts among the multiple coil parts disposed in the line.
A method of manufacturing a coil unit in a multi-axis linear motor actuator comprising a plurality of linear shaft motors arranged in a row at a predetermined pitch, the linear shaft motors each comprising a magnet portion for the linear shaft motor and a coil portion for the linear shaft motor, the magnet portion including a plurality of permanent magnets which are connected to each other with the same magnetic poles faced to each other and which are fixed to a support member having a length equal to or longer than a total length of the plurality of permanent magnets connected to each other to form a shaft, the coil portion including a plurality of cylindrical coils connected to each other in a center axis direction and combined with the shaft to be relatively movable with respect to an axial direction thereof with the shaft concentrically enclosed in the coil portion via a gap, the method including:
