Description

6-pole 10-slot concentrated winding motor {6Magnet 10Slot Concentrated Winding Motor}

The present invention relates to a motor having a six-pole, ten-slot concentrated winding type motor, and more particularly, to a motor using a winding pattern that maintains the performance of the motor and reduces the cost by controlling the number of poles and winding pitches.

Generally, in the case of various motors, a commutator and a coil are wound around a core to supply current from the outside, and the shaft is rotated by a magnetic field with the magnet to convert electric energy into rotational kinetic energy In the case of a DC motor such as a bar or an electric motor power steering (EPS) motor, current is supplied to a coil wound around a segment of a commutator and a slot of a core through a brush, The concentrated winding is divided into a concentrated winding and a distributed winding depending on how the coil is wound in the slot. The concentrating winding is a winding method in which the coil is wound concentrically in one slot. In the case of the distribution right including the coil winding method of the present invention, it is disclosed in Korean Patent Publication No. 79147 (published on July 5, 2006) Various winding methods have been developed, such as wave winding as described above, and lap winding as disclosed in Korean Patent Publication No. 1519 (published Jan. 11, 1994) In the case of a DC motor in which a coil is wound by a wave winding or a lap winding, the timing at which the brush of the same polarity contacts the commutator is different. Since the order of the coils wound in the core slot is different, The vibration was considerable, and the noise was severely generated.

FIG. 2 is an explanatory view of a winding pattern of a six pole, ten slot concentrated winding motor according to an embodiment of the present invention; FIG.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited by the scope of the present invention.

Referring to FIGS. 1 and 2, a six-pole 10-slot concentrated winding motor according to the present invention includes a motor case 100 having a six-pole magnet 110 formed therein; A core (200) forming ten slots to be mounted to the motor case (100) to which the magnet (110) is coupled; A rotating shaft (1) passing through the center of the core (200); A brush card 400 having at least one brush 410 coupled to an upper portion of the core 200; A commutator 300 coupled to the rotating shaft 1 and in contact with the brush 410 to form 20 divided hooks 200; A coil (c) wound on the hook of the commutator (300) and the slots of the core (200) at one pitch; And a motor cover (101) for shielding the motor case (100), wherein the coil (c) is wound over one pitch of the slots in a concentric winding manner and the winding direction is both clockwise or counterclockwise And includes a single or double winding method.

In the case of FIG. 2, the numbers of the respective numbers are written in the hooks of the commutator 300 and the slots of the core 200, but these are merely means for understanding, and the combinations of the numbers do not limit the winding.

1 and 2, the coil c according to the present invention is a concentrated winding method in which the coil c is wound concentrically in one slot, and is used due to the reduction in the winding pitch of the coil c. The total length of the entire coil c is reduced, resulting in a decrease in the height of the copper wire in the axial direction. As a result, the overall length of the motor can be reduced to reduce the motor size.

That is, as shown in FIG. 2, when the coil c is viewed in a plan view, that is, a shape facing the commutator 300 with respect to the core 200, the coil c is connected to the commutator 300, One slot of the core 200 is wound clockwise or counterclockwise at one pitch from the hooks of the starting commutator 300 among the adjacent commutator 300 hooks and then wound on the left or right side of the starting commutator 300 hook The two slots of the core 200 adjacent to one of the slots of the core 200 are wound clockwise or counterclockwise, and then the two slots of the core 200 are connected to the opposite side of the commutator 300 Pattern.

For example, when the coil (c) wound on the third commutator (300) hook is wrapped around the arbitrarily set slot (2) of the core (200), one pitch is crossed over the second commutator (300) It is a pattern that escapes between 2 and 3 and crosses 2 pitches and it is caught in the core (200) slots 4 and 5 and the 9th commutator (300) hooks.

In this type of winding method, of the single or double winding type, the single winding type is wound in the slots of the commutator 300 and the core 200 by using one coil (c) (c) is used to wire the slots of the commutator 300 and the core 200, and the coil (c) is preferably made of a copper wire of 0.4 to 0.75 pi.

Next, two or four brushes 410 may be provided, and when the brushes 410 are composed of two or four brushes 410, the same winding method may be applied.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
