Coil winding jig, electromagnet manufacturing method, electromagnet, motor, and recording medium driving device

摘要

There are provided a coil winding jig, an electromagnet manufacturing method, an electromagnet, a motor, and recording medium drive device capable of reducing the thickness of a motor. A status core (24) is formed by laminating a plurality of metal plates (27, 28) and having an annular core back (25) and a predetermined number of tooth electrodes (26). A coil winding jig (50) holds the status core (24) when winding coils (23u, 23v, 23w) on the tooth electrodes (26) of the status core (24). The coil winding jig (50) includes a mounting unit for mounting the status core (24), and a plurality of engaging protrusions (53) arranged on the inner circumference side of the core back (25) and having their tips protruding from the end surface of the core back (25) when the status core (24) is mounted on the mounting unit, for engaging at the outer side of the radial direction a connecting wire (41) electrically connecting between the coils (23u, 23v, 23w).
