Title:
DC MOTOR, AND WINDING METHOD OF COIL OF THE MOTOR
Document Type and Number:
Japanese Patent JP3802785
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a DC motor and a winding method of a coil of the DC motor wherein winding work of a stator coil can be completed simply, the generation of breakage and damage which are caused by polar chips can be avoided in a process of winding-up, and remarkable convenience is obtained in working or assembling.
SOLUTION: In the winding method of a coil of a DC motor, a single lead wire is supplied and wound around forming post in order by the scheduled number of windings, a stator coil having an even number of paired coils is formed, a first end and a second end are formed on the stator coil, and winding directions of two paired coils of the stator coil which are adjacent to each other are made opposite. The stator coil having an even number of paired coils is fixed on a base of the DC motor so as to face a permanent magnet of a rotor. As a result, constitution is so performed that the rotation of the rotor having the permanent magnet can be repulsed by magnetic force generated by making a current flow in the stator coil.
