Abstract
The invention discloses a circular stator plate of a motor and a manufacturing method, and aims at providing a stator plate for a motor stator, which is small in electromagnetic noise, high in motor efficiency and convenient to mount and a manufacturing method with high processing efficiency. The stator plate comprises a stator plate body which is in a circular hollow structure, wherein 72 stator core slots are formed in the stator plate body; positioning holes used for positioning are formed in the outer ring of the stator plate body. The manufacturing method of the circular stator plate of the motor comprises the following steps: 1, the plate blank size of the stator plate body is calculated; 2, a mold is manufactured according to the shape of the stator plate body; 3, a plate is machined into a plate blank piece of the stator plate body by the mold on a punch, wherein the punching pressure numerical value of the punch is 6-20 tons; 4, the plate blank piece of the stator plate body is inspected by a grinding machine, and burrs are removed. The circular stator plate of the motor and the manufacturing method are suitable for the manufacturing of the energy-saving and environment-friendly motor stator and the remoulding of the existing motor stator, so as to improve the efficiency.
Description
Technical field
The present invention relates to electric motors, specifically, relate to a kind of circular stator piece and manufacture method thereof of motor.
Background technology
In global resources, cure weary society, people strengthen day by day to the consciousness of energy-saving and emission-reduction low-carbon (LC) life, and country is at present also in promotion energy-saving and emission-reduction energetically, and by improving the mode of Motor Energy Efficiency, are one of approach of realizing this goal.Be widely used at present the motor in the fields such as industry, agricultural, business, building industry and traffic, the defect such as ubiquity efficiency is low, energy consumption is large, can not meet the requirement of efficient and energy-saving and emission-reduction.
Stator piece is the key components and parts in motor, and its material, inner circle size, excircle dimension, flute profile are big or small, how many etc. has direct impact to the efficiency of motor.Current existing stator piece mostly is 36 grooves, because the deficiency of groove number causes slot pitch larger, thereby causes motor stator leakage current value high, cannot improve electric efficiency, and have the defects such as electromagnetic noise is large, starting current is large.Therefore be necessary to research and develop a kind of new stator piece structure.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of electromagnetic noise is little, electric efficiency is high, easy for installation stator piece and the high manufacture method of a kind of working (machining) efficiency for motor stator.
For achieving the above object, the present invention is achieved by the following scheme:
1. a circular stator piece for motor, comprises stator lamellar body, and described stator lamellar body is circular hollow structure, and described stator lamellar body is provided with 72 stator coring grooves.
The external circle of described stator piece is provided with the location hole for locating.
The manufacture method of the circular stator piece of above-described motor, comprises the following steps:
(1) calculate blank extension size: the sheet material blank dimension that calculates stator lamellar body;
(2) mould manufacture: make mould by the shape of described stator lamellar body;
(3) blank blanking: with mould, sheet material is processed to the sheet material blank of stator lamellar body on punch press, the stamping pressure numerical value of punch press is 6-20 tons;
(4) finished product: use abrasive machine to check the sheet material blank of stator lamellar body, remove burr.
Compared with prior art, the present invention has following beneficial effect:
1. reduced electromagnetic noise.The present invention has increased the groove number of stator piece, has reduced slot pitch, and electromagnetism density is increased, and pitch smaller, has reduced electromagnetic noise.
2. improved electric efficiency.The present invention has reduced slot pitch, reduces motor stator leakage current value, has improved the efficiency of motor.
3. easy for installation.The present invention is provided with a mounting-positioning holes, when stator is assembled, can first be fixed, and facilitates the winding of copper cash.
4. cost is low, can be used for the transformation of existing motor.The present invention only need change the mfg. moulding die of stator, need not change the original assembling mode of motor, can be used for the transformation of existing motor.
