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

In the present invention a wire is hooked on a commutator piece (C7) and a commutator piece (C14), thereby forming a voltage equalization line therebetween, and a wire is wound in a distributed mannerbetween a slot (S13) and a slot (S2), thereby forming a main winding (R1). Next, a wire is hooked on a commutator piece (C1) and a commutator piece (C8), thereby forming a voltage equalization line therebetween, and a wire is wound in a distributed manner between a slot (S7) and a slot (S10), thereby forming a main winding (R2). Thus, the step for forming a voltage equalization line and the stepfor forming a main winding are repeated by changing the commutator pieces being hooked and changing the slots forming a main winding, until the number of hooking operations performed with respect to one commutator piece and the number of operations for forming a main winding with respect to one slot is the same number for all of the commutator pieces and all of the slots.

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.
