Abstract
A method for positioning a built-in control panel of a plastic package motor belongs to the technical field of motor manufacturing. The plastic package mold is characterized in that an axial positioning pin is arranged on an upper mold of the plastic package mold, a radial positioning pin and an axial positioning pin are arranged on a lower mold, the radial positioning pin and the axial positioning pin respectively support or press a control panel arranged between the upper mold and the lower mold, and then the control panel is subjected to plastic package. The invention ensures that the radial and axial positions of the control panel are accurately positioned in the plastic package process, improves the position precision of the control panel in the motor and reduces the failure rate of the motor.
Description
The present invention relates to a kind of location method of built-in control plate of plastic sealed dynamo-electric machine, belong to the motor manufacturing technology field.
Control board is a critical component in the plastic packaging brshless DC motor, it and wound stator all by plastic packaging in the plastic packaging casing, but because control board is a printed circuit board, various control elements all has fixing position relation with wound stator and rotor into and out of line end on the plate, and in the existing plastic package process, control board is not located in the plastic packaging process, causes motor plastic packaging rear control plate to produce radial and axial multiple displacement in casing, and the consequence of these displacements is:
1, the radial displacement of Hall element on the control board and stator core teeth groove causes the motor commutation zero-time inaccurate, thereby efficiency of motor is descended, and the shake when causing motor rotation.
2, the gap of Hall element and epitrochanterian sensing magnet ring changes, and makes accurately detection rotor position of Hall element, causes motor accurately not commutate.
3, because the displacement of control board might be broken the enamelled wire of the stator winding that welds with it, cause electrical fault.
The purpose of this invention is to provide a kind of control board that makes in the plastic packaging process can pinpoint location method of built-in control plate of plastic sealed dynamo-electric machine.
The present invention is a location method of built-in control plate of plastic sealed dynamo-electric machine, it is characterized in that on the mold of plastic package die, being provided with the axial location pin, radial location pin and axial location pin are set on bed die, withstand or push down the control board that places between the upper and lower mould respectively, then control board is carried out plastic packaging.Axial location pin in the described upper and lower mould is at least 3.
The present invention makes the control board of plastic packaging brshless DC motor in motor plastic packaging process, no matter all be subjected to accurate localization in radial and axial position, solved in the plastic packaging motor in the past all disadvantage that the displacement owing to control board produces, it at first is the sensing accuracy that has improved Hall element, make motor commutation reliable, next makes Hall element improve with respect to the original position precision of stator core teeth groove, thereby improved the operating efficiency of motor, prevent the shake in the motor operation course, make unlikely the breaking of line between control board and stator winding, reduced the failure rate of motor.
Accompanying drawing has provided the mould structure cutaway view in the plastic package process of the present invention.
1 is patrix among the figure; 2 is the axial location pin; 3 is control board; 4 is counterdie; 5 are the radial location pin; 6 is the axial location pin.
Below in conjunction with embodiment the present invention is further described;
During plastic packaging, earlier alignment pin 2 is inserted in the patrix 1, again radial location pin 5 and axial location pin 6 are inserted in the counterdie 4, two radial holes on the control board 3 are placed on two radial location pins 5 of counterdie, control board radially can not rotated, promptly radially located, several axial location pins 6 on the counterdie push up the position circuit board from bottom to top, again the some axial location pins 2 on the patrix are pushed down control board, the axial location of control board is located, then capsulation material is injected mould, promptly plastic packaging has become the plastic packaging casing of the stator core of built-in control board and band winding.Generally, axial location pin 2,6 is at least 3.
Claims (2)
1, a kind of location method of built-in control plate of plastic sealed dynamo-electric machine, it is characterized in that on the mold of plastic package die, being provided with the axial location pin, radial location pin and axial location pin are set on bed die, withstand or push down the control board that places between the upper and lower mould respectively, then control board is carried out plastic packaging.
2, by the described location method of built-in control plate of plastic sealed dynamo-electric machine of claim 1, it is characterized in that the axial location pin in the described upper and lower mould is at least 3.
