Description

The electronic motor of cutting

Technical field

The present invention relates to a kind of motor configuration, particularly relate to a kind of electronic electronic motor of cutting of cutting that is applied to.

Background technology

As shown in Figure 1; The existing electronic motor 100 of cutting mainly comprises one and is used for fixing at an electronic holder 10 in the housing 90, cut and is arranged at the magnet ring 11 in this holder 10; And rotor 12 that centers on by these holder 10 coatings and this magnet ring 11; This rotor 12 has the linking part 121 of this holder 10 of protrusion; This linking part 121 is used to link an eccentric wheel 91, and this eccentric wheel 91 of these rotor 12 interlocks can drive blade 92 reciprocating motions when rotating, so that the result of use of cutting off hair to be provided.

Yet this electronic motor 100 of cutting has following shortcoming:

1. this rotor 12 arm of force length of radially extending from an axle 122 can be subject to the structure of this magnet ring 11 and this holder 10, because arm of force length is restricted, so the torsion when rotating is still less.

2. this rotor 12 is in the confined space that this holder 10 is coated, to rotate, owing to be difficult for heat radiation, so can reduce this electronic useful life of cutting motor 100.

3. it is big that a winding 123 that is disposed on this rotor 12 takies volume, and the material use amount that causes winding the line is more, and manufacturing cost is high.

Summary of the invention

The object of the present invention is to provide a kind ofly can promote torsion, good heat dissipation effect, and the lower electronic motor of cutting of manufacturing cost.

The electronic motor of cutting of the present invention comprises a holder, a rotor unit, and two bearings; This holder comprises the arbor hole that surrounding wall that edge one axis extends and center on, are formed in this surrounding wall and extend along this axis from fixed wall that this surrounding wall radially extends; And one be sheathed on the winding of the outer peripheral face of this surrounding wall along this axis, and this winding and this fixed wall are along this axis direction arranged spaced; This rotor unit comprises that one passes the axle of this arbor hole, the magnet ring around this winding along this axis, and an arm of force that radially is connected to this magnet ring from this axle; Said bearing be arranged at the two ends of this surrounding wall respectively and be connected in this surrounding wall and this axle between.

The electronic motor of cutting of the present invention, the fixed wall of this holder is near a wherein end of this surrounding wall, and the axle of this rotor unit has a linking part, and this linking part protrudes from the end of this surrounding wall near this fixed wall.

The electronic motor of cutting of the present invention, the fixed wall of this holder is near a wherein end of this surrounding wall, and the axle of this rotor unit has a linking part, and this linking part protrudes from the other end of this surrounding wall.

Beneficial effect of the present invention is: because this winding and this fixed wall are along this axis direction arranged spaced; The configuration of this magnet ring can not receive the structural limitations of this fixed wall; So it is long that the length of this arm of force can existingly design, just can produce bigger torsion output during this rotor unit running; And because this winding do not coated fully, and this rotor unit can produce air-flow when rotating, so this electronicly cuts the advantage that motor possesses good heat dissipation effect; In addition, the shared volume of this winding is less, so coiling material use amount is lower, so can reach the lower effect of manufacturing cost.

Description of drawings

Fig. 1 is a sketch map, and existing electronic structure of cutting motor is described;

Fig. 2 is a sketch map, and electronic one first preferred embodiment of cutting motor of the present invention is described;

Fig. 3 is a sketch map, and electronic one second preferred embodiment of cutting motor of the present invention is described.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.

As shown in Figure 2, electronic first preferred embodiment of cutting motor 200 of the present invention comprises a holder 20, a rotor unit 30, and two bearings 40.

This holder 20 is used for fixing electronic cutting in the housing 90; And comprise that edge one axis X is extended and the surrounding wall that centers on 21, one are formed in this surrounding wall 21 and along the arbor hole 23 that this axis X is extended, reach a winding 24 that is sheathed on the outer peripheral face of this surrounding wall 21 along this axis X from fixed wall that this surrounding wall 21 radially extends 22, one.

This fixed wall 22 is close to a wherein end of this surrounding wall 21; The radially formed holder width W 1 of this fixed wall 22 touches this electronic medial surface of cutting housing 90 greater than the radially formed rotor width W2 of this rotor unit 30 so this rotor unit 30 was unlikely when rotating.

This winding 24 is along this axis X direction arranged spaced with this fixed wall 22.

This rotor unit 30 comprises that one passes the axle 31 of this arbor hole 23, the magnet ring 32 around this winding 24 along this axis X, and an arm of force 33 that radially is connected to this magnet ring 32 from this axle 31.

This axle 31 has a linking part 311, and in the present embodiment, this linking part 311 protrudes from the end that this surrounding wall 21 is close to this fixed wall 22.

This linking part 311 is used to link an eccentric wheel 91, and this eccentric wheel 91 of these rotor unit 30 interlocks can drive blade 92 reciprocating motions when rotating, so that the result of use of cutting off hair to be provided.

Said bearing 40 is arranged at the two ends of this surrounding wall 21 respectively and is connected between this surrounding wall 21 and this axle 31.

As shown in Figure 3, second preferred embodiment of the present invention is similar to this first preferred embodiment, and its difference part is that this connecting portion 311 also can protrude from the other end of this surrounding wall 21, promptly is away from an end of this fixed wall 22.

Whereby, because this winding 24 is that the configuration of this magnet ring 32 can not receive the structural limitations of this fixed wall 22 along this axis X direction arranged spaced with this fixed wall 22; So it is long that the length of this arm of force 33 can existingly design, just can produce bigger torsion output during these rotor unit 30 runnings, follow; Because this winding 24 is not coated fully, and this rotor unit 30 can produce air-flow when rotating, so this electronicly cuts the advantage that motor 200 possesses good heat dissipation effect; In addition; The shared volume of this winding 24 is less, so coiling material use amount is lower, so can reach the lower effect of manufacturing cost.
