Abstract
The characteristic is that stator of motor is jogged by spliced block type iron-cores, which are I shaped and toothed units, after being coiled, First, on the spliced block type iron-cores then to join them to form a unitary stator and forming epoxy sealing. The locating concave slot and locating convex rib which are adapted each other at the jogged position of spliced block type iron-core. The invention can enhance winding manufacturatility for stator iron-core, simplify winding process, increase winding work effeciency of stator iron-core with reliability of the motor effectively.
Description
The present invention relates to a kind of plastic sealing technique of plastic sealed electric machine with assembled piece type stator iron core, belong to the motor manufacturing technology field.
The stator core of existing plastic packaging motor is all-in-one-piece, promptly winds the line on the stator core of integral body, carries out plastic packaging again, because motor adopts whole apart from concentrating coil, directly on stator tooth, the coiling movement locus is tetragonal unrolling to coil, so very difficult to the one-piece stator coiling, and electromagnetic wire is wiped mutually with iron core and is caused short circuit easily, its qualification rate and operating efficiency are lower, and reliability is not high, and material is wasteful, must design complicated special-purpose coil winding machine when producing in batches also, invest bigger.
The purpose of this invention is to provide and a kind ofly can effectively improve stator core coiling work efficiency and motor rotation reliability, save material the plastic sealing technique of plastic sealed electric machine with assembled piece type stator iron core that reduces cost.
The present invention is a plastic sealing technique of plastic sealed electric machine with assembled piece type stator iron core, it is characterized in that being spliced after the assembled piece type iron core coiling of motor stator by " worker " font tooth unit formation, this assembled piece type iron core comprises tooth portion and yoke portion, its technology be earlier on the assembled piece type iron core after tooth portion insulation processing the coiling solenoid, become the assembled piece type stator, then the assembled piece type stator is spliced into unitary stator in yoke portion, carries out the plastic packaging moulding at last, be packaged with the plastic packaging casing of stator in the formation.
Splicing place at described assembled piece type iron core yoke portion two ends also can be provided with the detent and the location convex tendon of working in coordination; Described detent and location convex tendon can be arc line type or broken line type, or the structure such as compound of camber line and broken line.
The quantity of described assembled piece type iron core equates with the stator number of teeth; The yoke portion outside of described assembled piece type iron core can be cambered surface or plane or folding face etc.
The material of described plastic packaging casing can be thermoset plasticses such as phenolic resins or the epoxy resin that contains filler, or mylar.
For the overall structure that makes plastic packaging motor is compact more, the present invention also can be located at the envelope of the circuit for controlling motor plate on the plastic packaging motor in the plastic packaging casing when the moulding of motor stator plastic packaging simultaneously.
The present invention has changed the coiling plastic package process of existing plastic packaging motor, improved the winding process of stator core, coiling is carried out in free space, be convenient to manual and mechanical coiling, simplified method for winding, improved the coiling work efficiency, and do not needed special complicated coil winding machine, coiling campaign of the present invention is a circumferential, prevented the scratch of electromagnetic wire effectively, thereby improved the operating reliability of product percent of pass and motor, simultaneously, owing to adopt the assembled piece type core structure, improved the utilance of stator core material greatly, can save material, reduce cost, be particularly suitable for the production of plastic package brushless direct current motor.
