It the utility model is related to a kind of water pump brushless electric motor rotor iron core, a kind of water pump brushless electric motor rotor iron core, including the rotor core formed by laminating with axial punch and some magnetic sheets for being fixed on rotor core periphery, the rotor core center is provided with circular hole, periphery is provided with some necks to cave inward, the magnetic sheet is corresponded with rotor core by neck, fixed fitting, and magnetic sheet and the lower surface arc radius and the arc radius of rotor core that rotor core is bonded are close or equal.The utility model has the advantage of with timely heat-sinking capability rapidly, make magnetic sheet damage difficult for drop-off;The volume for reducing rotor core causes the faster rotational speed of rotor, improves operating efficiency.

Description

A kind of water pump brushless electric motor rotor iron core
Technical field
It the utility model is related to a kind of water pump brushless electric motor rotor iron core.
Background technology
Due to the rapid development of scientific and technological level, the technology of brushless electric machine has obtained very big development, and water pump brushless electric machine turns Sub- iron core also accordingly obtains different degrees of improvement.But existing water pump brushless electric motor rotor iron core also has the following disadvantages:Turn Sub- iron core is mostly fixedly connected with magnetic sheet by binding agent, in use, can be come off caused by ageing of binders, and shadow Motor radiating is rung, operating noise is big, and behavior in service is poor;The volume of rotor core is big, and the operating efficiency for causing motor to operate is low, system Make cost height.
Utility model content
For above-mentioned weak point of the prior art, the purpose of this utility model is that providing one kind has good heat radiating Function, low noise, the water pump brushless electric motor rotor iron core of small volume.
The utility model is achieved through the following technical solutions:
A kind of water pump brushless electric motor rotor iron core, including the rotor core that is formed by laminating with axial punch and be fixed on Some magnetic sheets of rotor core periphery, the rotor core center are provided with circular hole, and periphery is provided with some necks to cave inward, institute State magnetic sheet to correspond by neck with rotor core, fixed fitting, and the lower surface circular arc half that magnetic sheet is bonded with rotor core Footpath and the arc radius of rotor core are close or equal.
Preferably, the thickness of the rotor core is 0.3-0.7 millimeters.
Preferably, the rotor core uses 470 steel discs.
Preferably, the outer circumference diameter of the rotor core is 26-30 millimeters, a diameter of 6-10 millimeters of central circular hole, neck For 6-10.
Compared with the prior art, the beneficial effects of the utility model are, are fixed by the neck on rotor core with magnetic sheet Engaging, and the structure design that magnetic sheet is bonded completely with the contact surface of neck, there is rapid timely heat-sinking capability, be not easy magnetic sheet Come off damage;The volume for reducing rotor core causes the faster rotational speed of rotor, improves operating efficiency.
Brief description of the drawings

Embodiment
In order that technical problem, technical scheme and beneficial effect that the utility model solves are more clearly understood, below In conjunction with the embodiments, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only To explain the utility model, it is not used to limit the utility model.
In description of the present utility model, the orientation or position relationship of the instruction such as term "left", "right" is based on accompanying drawing institutes The orientation or position relationship shown, is for only for ease of description the utility model, rather than requires that the utility model must be with specific Azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
As depicted in figs. 1 and 2, a kind of water pump brushless electric motor rotor iron core, including turned by laminating with what axial punch formed Sub- iron core 1 and some magnetic sheets 2 for being fixed on rotor core periphery, rotor core center are provided with circular hole 3, periphery provided with it is some to The neck 4 of sunken inside, magnetic sheet 2 are corresponded with rotor core 1 by neck 4, fixed fitting, and magnetic sheet 2 and rotor core 1 The lower surface arc radius of fitting is close or equal with the arc radius of rotor core 1.The thickness of rotor core 1 is 0.3-0.7 Millimeter.The outer circumference diameter of rotor core 1 is 26-30 millimeters, and a diameter of 6-10 millimeters of central circular hole 3, neck 4 is 6-10.
Embodiment 1
In the present embodiment, the outer circumference diameter of rotor core 1 is 28.3 millimeters, 3 a diameter of 8 millimeters of central circular hole, rotor iron Core uses 470 steel discs, and the thickness of rotor core 1 is 0.5 millimeter.
In the present embodiment, magnetic sheet 2 and neck 4 are 8 in correspondence with each other, wherein, magnetic sheet 2N poles and S are extremely each four, according to N Pole, the order of S poles are accordingly inserted into the neck 4 of rotor core periphery and are fixed.
Preferred embodiment of the present utility model is the foregoing is only, not to limit the utility model, therefore, only This is should be included in all any modification, equivalent and improvement that the utility model specification and drawings content is made etc. Within the protection domain of utility model.
