Embodiment Construction

[0052] Next, based on Figure 1 to Figure 6 A first embodiment of the present invention will be described.

[0053] Such as figure 1 , figure 2 As shown, the motor 1 is a driving source of an electrical component (for example, a radiator fan) mounted on a vehicle, and has a structure in which an armature 3 is rotatably arranged in a bottomed cylindrical motor case 2. . A plurality of permanent magnets 4 are fixed in the circumferential direction on the inner peripheral surface of the motor housing 2 . Specifically, there are eight permanent magnets 4 , that is to say, there are eight magnetic poles.

[0054] The armature 3 is composed of an armature core 6 fixed to the rotating shaft 5 , an armature coil 7 wound around the armature core 6 , and a commutator 13 disposed on one end side of the armature core 6 . The armature core 6 has a structure in which a plurality of ring-shaped metal plates 8 are laminated in the axial direction. On the outer peripheral portion of the...

Abstract

A DC motor armature (3) is an 8-pole, 10-slot, 20-segment type or a 12-pole, 15-slot, 30-segment type. A commutator has a connection line (25) arranged for making a shortcircuit between the segments (14) having the same potential. A winding (12) is electrically connected between segments (14) having a potential difference equivalent to the potential difference between the adjacent segments (14). The winding (12) is wound on the teeth (9) so as to form an armature coil (7). Thus, it is possible to provide a DC motor armature, a DC motor, and a DC motor armature winding method so as to obtain asmall-size 3-phase DC motor having a long service life and a high efficiency.

Description

technical field [0001] The present invention relates to an armature of a DC motor mounted on a vehicle or the like, a DC motor, and an armature winding method of the DC motor. [0002] This application claims priority based on Japanese Patent Application No. 2006-293868 filed at the Japan Patent Office on October 30, 2006, and Japanese Patent Application No. 2007-276373 filed at the Japan Patent Office on October 24, 2007, and is incorporated herein by reference its content. Background technique [0003] Conventionally, brushed DC motors mounted on vehicles and the like are known. This DC motor has a structure in which an armature around which an armature coil is wound is rotatably arranged inside a cylindrical yoke having an even number of magnets attached to the inner peripheral surface. The armature has an armature iron core embedded and fixed on the rotating shaft. Tees for winding a winding are radially formed on the armature core in the circumferential direction, an...
