STRUCTURE OF MAGNETIC CONDUCTION PIECE OF MOTOR STATOR COMPOSED OF SINGLE MAGNETIC CONDUCTION PIECE

摘要

PROBLEM TO BE SOLVED: To provide the structure of the magnetic conduction piece of a motor stator composed of a single magnetic conduction piece that can be reduced in the number of members and thickness in the axial direction by forming magnetic pole pieces, magnetic pole planes and axial holes of the motor stator by punching the single magnetic conduction piece, can simplify a structure as a whole since the magnetic pole piece, can place a coil and the stator member such as a circuit plate as a base seat of the motor stator, and also can be reduced in manufacturing cost.;SOLUTION: The structure is constituted of the magnetic pole piece and a plurality of magnetic pole planes and axial holes. The magnetic pole pieces, the magnetic pole planes and the axial holes are formed at the single magnetic conduction piece, and the magnetic pole pieces can be connected to the coil as the base seat of the stator. The magnetic pole planes are formed by punching the single magnetic conduction piece arranged around the axial holes in a ring-shape, and formed so as to be adjacent to the coil. The axial holes are formed so as to support a rotor by being coupled to a fixed seat.;COPYRIGHT: (C)2004,JPO&NCIPI
