Embodiment approach 1

[0035] figure 1 It is a sectional view showing the motor 1 according to Embodiment 1 of the present invention. Motor 1 is a brushed DC motor with distributed windings.

[0036] In a space surrounded by the case 2 and the brush holder 3 , a shaft 4 is rotatably supported. A commutator 5 and a laminated rotor core 6 are fixed to the shaft 4 .

[0037] The commutator 5 is in partial contact with the brushes 7 supported by the brush holder 3 .

[0038] Coils 8 are formed on the rotor core 6 . Viewed from the rotor core 6 , the magnet 9 and the yoke 10 supported by the case 2 are arranged on the outer peripheral side.

[0039] here, in figure 2 extracted and shown from figure 1 The commutator 5 and the rotor core 6 viewed from the A direction.

[0040] In the illustrated example, the commutator 5 has 14 commutator segments 51 . The plurality of commutator segments 51 are arranged side by side in the circumferential direction with respect to the rotation axis direction of t...

Abstract

The invention provides a motor and a winding method of the motor. Hook the wire to the commutator (C7) and the commutator (C14) to form an equalizing line between them, distribute and wind the wire between the gap (S13) and the gap (S2) to form the main winding (R1) . Then the wire is hooked to the commutator piece (C1) and the commutator piece (C8) to form an equalizing line between them, and the wire is distributed and wound between the gap (S7) and the gap (S10) to form the main winding (R2 ). In this way, the commutator segments to be hooked and the gaps forming the main winding are changed, and the process of forming equalizing lines and the process of forming the main winding are repeated until one commutator segment is formed in all commutator segments and all gaps. The number of times of being hooked and the number of times of forming the main winding for one slit are the same.

Description

technical field [0001] This invention relates to electric motors, and more particularly to rotor windings for electric motors. Background technique [0002] For example, Patent Document 1 describes a DC brushed motor obtained by manufacturing a coil by sequentially forming a plurality of repeatedly wound portions of an electric wire starting from one of the elements constituting a commutator. The hook, that is, the first joint, is introduced into the tooth space that is the same phase as the first joint, that is, the first space. The second inter-teeth is led out, and ends at the second engagement portion which is a hook formed on the same element as the second inter-teeth. [0003] In addition, in such a motor, in addition to repeatedly winding the teeth, it is necessary to arrange a voltage equalizing line so that the elements of the commutator located at the opposite corners have the same potential.
