摘要

This linear motor has: a coil unit (21) composed of multiple coil assemblies (20); and permanent magnets. Each coil assembly (20) has a cylindrical bobbin (27) around which a coil (32) is provided. A wire connection pin (35a) for connecting to one end of a magnet wire (31) is provided on one end of the bobbin (27), and a wire connection pin (35b) for connecting to the other end of the magnet wire is provided on the other end of the bobbin (27). Connection sections (33b, 33c) serving as joint sections are provided on each bobbin (27), whereby wire connection pins (35a, 35b) of the coil assemblies (20) in the same phase are connected together via joint metal fittings (37) inserted in the connection sections (33b, 33c).
