Abstract
The invention belongs to the technical field of motors, and particularly relates to a method for transforming and utilizing a waste motor. The transformation technology comprises a stator transformation method and a rotor transformation method. A new stator pole and a new rotor pole are fixedly installed through dismantling and cutting an original winding and an original iron core structure, and positioning and combination are carried out again. The beneficial effects are that utilization values of the motor are restored, the method is simple, effective and low in investment cost, cyclic utilization of resources is promoted, and waste is avoided, thereby being conducive to producing good economic benefits and social values.

Technical field
The invention belongs to motor technology field, particularly a kind of renovation and utilization method of waste and old motor.
Background technology
At present, motor is made up of rotor and stator two parts, and it is used to the conversion equipment realizing electric energy and mechanical energy and mechanical energy and electric energy.And the iron core of rotor and stator is normally formed by insulating varnish closed assembly by silicon steel sheet, motor is in long-term use procedure, due to aging, make moist, be heated, the factor such as weather, performance index are deteriorated, or even cause the insulating varnish between stator, rotor core silicon steel sheet to burn gelatinization phenomenon, lose insulation effect, finally cause the forfeiture value of motor, motor (as JO series) efficiency as old is low, power factor is low, country explicit order eliminates, and causes resource, energy waste.
Summary of the invention
The present invention, in order to solve above asking a question, makes up the deficiency of conventional art, provides a kind of small investment, the motor of instant effect transforms, recover the renovation and utilization method of its value.
The present invention is achieved through the following technical solutions:
A renovation and utilization method for waste and old motor, is characterized in that: comprise stator transformation method and rotor retrofit method:
A. stator transformation method step is:
1) cut off, remove winding: in the iron core end of stator coils of motor, cut off coil winding overhang; Stator is heated, softening insulating varnish, and then detach dismounting stator winding;
2) cleaning, cutting stator iron core: adopt physical erase mode, carries out scale removal cleaning to the iron core after removing stator winding; After cleaning out, adopt Linear cut mode, the iron core after cleaning is cut into the reeded inner peripheral surface of band;
3) fixed stator pole: formed by silicon steel sheet closed assembly or the oblong-shaped stator poles of ferromagnetic material, and the groove match of the end of stator poles and stator core, again by weld or bolt is fixed after the end clamping of stator poles is inserted into stator core;
4) stator poles winding is installed: recalculate magnetic flux, coil turn, determine coil assembly, and be installed in stator poles;
B. rotor retrofit method step is:
1) cutting rotor iron core: adopt Linear cut mode, is cut into the reeded outer circumference surface of band;
2) fixed rotor pole: formed by silicon steel sheet closed assembly or the oblong-shaped rotor pole of ferromagnetic material, and the groove match of the end of rotor pole and rotor core, again by weld or bolt is fixed after the end clamping of rotor pole is inserted into rotor core;
C. being assembled of stator and rotor: improved stators and rotators is carried out reorientating and assembling, guarantees that stator poles and rotor pole exist gap.
Prioritizing selection, the groove of described stator core inner peripheral surface is dovetail shaped groove; The end that stator poles and stator core match is all dovetail shaped structure.
Prioritizing selection, the groove of described rotor core outer circumference surface is dovetail shaped groove; The end that rotor pole and rotor core match is all dovetail shaped structure.
Prioritizing selection, softens insulating varnish to stator, adopts electric dry oven or oven heating.
The invention has the beneficial effects as follows, pass through simple effective method, by the transformation again to stator and rotor structure, superseded motor is realized to be converted to switched reluctance motor, recover motor value, recycling of the resource promoted, avoids causing waste, is conducive to producing good economic benefit and social value.
