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

摘要

Provided are a coil winding jig, an electromagnet manufacturing method, an electromagnet, a motor, and a recording medium driving device capable of reducing the thickness of the motor. When the coils 23u, 23v, 23w are wound around the tooth poles 26 of the stator core 24, which is formed by laminating a plurality of plate bodies 27, 28 made of metal and having an annular core back 25 and a predetermined number of tooth poles 26, A coil winding jig 50 for holding the stator core 24, which is placed on the inner peripheral surface side of the core back 25 when the stator core 24 is placed on the placement portion on which the stator core 24 is placed. A plurality of locking projections 53 that are arranged in a protruding state from the end surface of the core back 25 and lock the crossover wire 41 that electrically connects the coils 23u, 23v, and 23w radially outward. It is characterized by having.
