Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
It should be noted that when component is referred to as " being fixed on " another component, it can be directly on another component
Or there may also be component placed in the middle.When a component is considered as " connection " another component, it can be directly connected to
To another component or it may be simultaneously present component placed in the middle.When a component is considered as " being arranged at " another component, it
Can be set directly on another component or may be simultaneously present component placed in the middle.Term as used herein is " vertical
", " horizontal ", "left", "right" and similar statement for illustrative purposes only.
Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to technology of the present utility model
The implication that the technical staff in domain is generally understood that is identical.It is simply in term used in the description of the present utility model herein
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include
The arbitrary and all combination of one or more related Listed Items.
Fig. 1 and Fig. 2 is referred to, in the first embodiment, a kind of multipole DC micromotor 100 includes casing 10, magnetite
20th, rotor 30 and rotating shaft 40.
Rotating shaft 40 is rotatablely installed inside casing 10, and rotor 30 is fixed on rotating shaft 40.Magnetite 20 is fixed on casing 10.Magnetite
20 in circular and be integrally formed.Rotor 30 is located in magnetite 20.Magnetite 20 is bonded neodymium-iron-boron or ferrite or rubber magnet
Bar, 4 poles are magnetized.
The length L1 of rotor 30 is 10-15mm.When the length L1 of rotor 30 is less than 10mm, coiling line pole reduces, direct current generator
Resistance diminishes, heating increase.When the length L1 of rotor 30 is more than 15mm, in the confined space of DC micromotor, rotor 30
Length L1 is excessive, and the component such as DC micromotor internal rectifier and brush does not just have space mounting.The external diameter of rotor 30 is 10-
20mm.When the external diameter of rotor 30 is less than 10mm, the back winding space of rotor 30 diminishes, and coil resistance reduces, heating increase.When turn
When sub 30 external diameters are more than 20mm, in the case where the size of casing 10 is certain, magnetite 20 is too thin, and the effective thickness of magnetite 20 diminishes, magnetic
Power is inadequate, causes Motor torque inadequate.
The length L2 of magnetite 20 is 10-20mm.When the length L2 of magnetite 20 is less than 10mm, magnetite 20 effectively will can not entirely turn
Subcoil is wrapped in magnetic field, and magnetic field utilization rate reduces.When the length of magnetite 20 is more than 20mm, whole motor weight is big, volume
Greatly, not meeting utility model reduces the purpose of weight and volume.The thickness of magnetite 20 is 0.7-3.5mm.When the thickness of magnetite 20 is less than
During 0.7mm, the processing difficulties of magnetite 20, and intensity deficiency, easily collapse scarce.When the thickness of magnetite 20 is more than 3.5mm, whole motor
Weight is big, and volume is big, and not meeting utility model reduces the purpose of weight and volume.
The length L3 of casing 10 is 18-32mm.When the length L3 of casing 10 is less than 18mm, the actuator of client can not be just
Often installation, and installing space is too small inside direct current generator, and inner body can not be installed.When the length L3 of casing 10 is more than 32mm
When, whole motor weight is big, and volume is big, and not meeting utility model reduces the purpose of weight and volume.The external diameter of casing 10 is 18-
25mm.When the external diameter of casing 10 is less than 18mm, the actuator of client can not normal mounting, and installation is empty inside direct current generator
Between it is too small, inner body can not be installed.When the external diameter of casing 10 is more than 25mm, whole motor weight is big, and volume is big, does not meet
Utility model reduces the purpose of weight and volume.
The ratio between the length L3 of casing 10 and the length L1 of rotor 30 are 1.2-3.2.The length L2 of magnetite 20 and the length of casing 10
The ratio between L3 is 0.3125-1.11.The ratio between the thickness of magnetite 20 and the external diameter of rotor 30 are 0.035-0.35.The length L3 and machine of casing 10
The ratio between external diameter of shell 10 is 0.72-1.78.Casing 10 is formed by Zinc-coated steel-plated punch.The thickness of casing 10 is more than 0.75mm.
Please continue to refer to Fig. 3, in a second embodiment, a kind of structure of multipole DC micromotor 100 and first embodiment
Middle structure is roughly the same, and difference is that circular magnetite 20 is interfixed by some arc magnetites 20 and is spliced.Some arcs
Shape magnetite 20 makes to contact with each other so as to form physical connection between magnetite face by glue or fixed seat.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
