A cable-through hole 321.
As shown in figure 9, there are two positioning tooths 320 for the secondary tool of iron core 300, the distance between two positioning tooths 320 are equal, each
The shape of positioning tooth 320 is different, and there are three cable-through hole 321, another positioning tooths 320 to have four for the tool of one of positioning tooth 320
A cable-through hole 321.
As shown in Figure 10, there are two positioning tooths 320 for the tool of secondary iron core 300, and the distance between two positioning tooths 320 are equal, and two
The shape of a positioning tooth 320 is different and is made of respectively multiple rectangular teeths, and one of positioning tooth 320 has there are four rectangular teeth,
There are five rectangular teeths for another positioning tooth 320 tool.
Contact area can be improved by increasing the toothing of positioning tooth 320 in this way, or by reducing positioning tooth 320
Toothing reduces cost.Meanwhile the quantity of positioning tooth 320 is fewer, the toothing of positioning tooth 320 is bigger, single tooth positioning tooth
320 is bigger with the contact area of the first main iron core 110 or the second main iron core 120, the binding force between secondary iron core 300 and main iron core
It is more secured, it is possible thereby to reduce the risk of 320 fins of positioning tooth.
Specifically, quantity when positioning tooth 320 is uniformly distributed on secondary iron core 300 is less than the first main iron core 110 and the second main iron core
The quantity of skewed slot on 120.
Optionally, the thickness of secondary iron core 300 is less than or equal to 3 millimeters.It will be appreciated herein that thickness only refers to secondary iron core
300 thickness of itself do not include the other structures being additionally arranged thereon.It can make secondary iron core 300 that there is rational size in this way,
To make connection ring 230 that there is rational thickness.
Specifically, the diameter of secondary iron core 300 is less than or equal to the slot bottom inscribed circle of the first skewed slot 111 and the second skewed slot 121
Diameter.It will be appreciated herein that " diameter of secondary iron core 300 " refers to the diameter for not including positioning tooth 320.That is, secondary iron
The root diameter of core 300 is less than or equal to the root diameter of the first main iron core 110 and the second main iron core 120, i.e., pair iron core 300 does not wrap
The diameter for including 320 part of positioning tooth is less than or equal to the first main iron core 110 and the slot bottom of the second main iron core 120 and all skewed slots is tangent
Circular diameter.In other words, secondary iron core 300 does not include that the outer periphery of positioning tooth 320 is no more than the slot bottom of skewed slot radially.In this way
Not only first skewed slot 111 and the second skewed slot 121 can be caused to block to avoid secondary iron core 300, further be convenient for cage winding 200
Formation, when convenient for ensureing that rotor 1 works can Positive rotational, and be easy to implement secondary iron core 300,110 and of the first main iron core
Second main iron core 120 is completed by a punching of high stamping die.
Optionally, as depicted in figs. 1 and 2, the first skewed slot 111 and the second skewed slot 121 is in the axis of secondary iron core 300
Minimum angles it is identical and angle of inclination is opposite.The skewed slot opposite by the way that angle of inclination is arranged in this way, can make rotor 1 be powered
Generate that both direction is opposite and symmetrical axial force is so that it can cancel out each other, convenient for reducing the additional torque of rotor 1, just afterwards
In the mechanical wear for reducing rotor 1, convenient for improving the working performance of the motor, convenient for improving the efficiency of the motor, it is convenient for
Extend the service life of the motor.The torsion that rotor 1 not only can be improved, in order to improve the working efficiency of rotor 1,
To improve the working efficiency of the motor, and the electromagnetism HARMONIC FORCE of rotor 1 can be reduced, be generated to reduce the motor
Noise, improve the noise reduction capability of the motor, improve the comfort of user.
According to one embodiment of present invention, as shown in Figure 1, the first skewed slot 111 towards one end of the second main iron core 120 with
One end being axially aligned in secondary iron core 300 of second skewed slot 121 towards the first main iron core 110.It not only can reduce and pour
The resistance that the first skewed slot 111 and the second skewed slot 121 are filled when type casting moulding allows the swimmingly cast molding of cage winding 200, and
And the structure that the first skewed slot 111 and the second skewed slot 121 are filled can be kept more continuous neat, just when casting cage winding 200
In the structural strength for improving cage winding 200, to improve the structural strength of rotor 1, make the structure of rotor 1 is more firm can
It leans on.
Also, by the way that the first skewed slot 111 is led towards one end of the second main iron core 120 and the second skewed slot 121 towards first
One end of iron core 110 is axially aligned secondary iron core 300, the Distribution of Magnetic Field on rotor 1 can be made more uniform in this way, due to
Rotor 1 interacts with the motor stator, rotor 1 can be made to be rotated relative to the stator of the motor, so as to carry
The stability and uniformity that high rotor 1 rotates, the mechanical energy of rotation are converted electrical energy into convenient for the motor stabilizing, convenient for carrying
The performance of the high motor.
According to another embodiment of the invention, the first skewed slot 111 is towards one end of the second main iron core 120 and the second skewed slot
121 are staggered towards one end of the first main iron core 110 in the axial direction of secondary iron core 300.For example, the first skewed slot 111 is distributed on first
On main iron core 110, the second skewed slot 121 is distributed on the second main iron core 120, the distance between adjacent two first skewed slots 111
The distance between two adjacent the second skewed slots 121 are equal, and the first skewed slot 111 is towards one end of the second main iron core 120 and the
The distance that one end of two skewed slots 121 towards the first main iron core 110 is staggered in the axial direction of secondary iron core 300 is less than adjacent two the
The half of distance between one skewed slot 111.The required precision of rotor 1 can be reduced in this way, led convenient for the first main iron core 110 and second
The processing and manufacturing and assembly of iron core 120 are not only convenient for improving the processing efficiency of rotor 1, reduce the production cost of rotor 1, and
Convenient for improving the efficiency of assembling of rotor 1, the assembly cost of rotor 1 is reduced.Simultaneously as there are manufacture deviation or electricity for the motor
Magnetic design defect, 121 stagger setting of the first skewed slot 111 and the second skewed slot, can reduce manufacture deviation or electromagnetic design defect pair
The influence of rotor 1 is further convenient for ensureing the functional reliability of rotor 1, is further convenient for improving the working efficiency of rotor 1, into
The noise that one step generates convenient for the reduction motor.
