Abstract
This invention relates to a motor rotor surface pickling technique which is applied in reducing the iron loss and stray load loss in cage induction motor rotors. It is unique that rotors not eligible in frequency testings are screened out for pickling at first and then processed as follows. Firstly, the rotor is lathed by 0.10mm in outer circle. Secondly, hydrochloric acid and water are mixed into solution at a ratio of 1:1. Thirdly, the whole outer circle surface of the rotor is treated with hydrochloric acid solution. Fourthly, the entirely treated rotor is placed into an oven for drying without definite time limitation. This invention beneficially reduces the stray load loss to 1/5 of the original value at most and promotes the motor efficiency, typically by 0.5~1.5% for middle or small low-voltage motors.
Description
Technical field
The present invention relates to a kind of cleanup acid treatment technology, relate to a kind of treatment technique for acid washing surface of electronic rotor or rather, belong to the motor manufacturing technology technical field.
Background technology
Programme of cage asynchronous motor is a kind of normal asynchronous wide, that price is lower of using, and its structure comprises stator and rotor, and rotor generally adopts the pressure aluminum process, to reduce cost, satisfies simultaneously and produces needs in enormous quantities.
But the pressure cast aluminium easily causes the contact resistance between rotor cage bar and iron core to reduce, thereby has increased the core loss and the load stray loss of rotor, and the efficient of electric motor is reduced, and the stator winding temperature rise improves.
At present, some motor manufacturers, in order to improve the motor effect, to reduce core loss and load stray loss, the high-efficiency electric motor that assurance exports to countries such as the U.S. reaches the CSAC390 efficiency index, and the motor efficiency testing method is according to the method test of IEEE112B, to satisfy the export standard requirement.
Summary of the invention
The object of the present invention is to provide a kind of treatment technique for acid washing surface of electronic rotor, this treatment process adopts pickling, and method Tong is single, cost is low, effective.
In order to achieve the above object, technical solution scheme of the present invention is: the present invention adopts 1: 1 the hydrochloric acid and the solution of water to clean, the corrodible sub-surface of turning round is owing to the aluminium that turning is pressed in the iron core is considered to be worth doing, and the aluminium that links to each other with rotor slot palpus, increases the contact resistance between cage bar and iron core.
Beneficial effect of the present invention: can reduce electric motor stray loss significantly, improve motor efficiency, handle best stray loss can be reduced to 1/5 of initial value,, can raise the efficiency 0.5%～1.5% to the middle-size and small-size electric motor of low pressure.
Description of drawings
Fig. 1 reduces electric motor stray loss processing technological flow figure significantly for a kind of pickling of the present invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is done more detailed explanation.
With reference to Fig. 1, this is that pickling of the present invention reduces electric motor stray loss processing technological flow figure significantly.
As shown in the figure, treatment technique for acid washing surface of electronic rotor, its processing method step is:
Earlier the substandard rotor of all efficiency tests is picked out, as the rotor that carries out pickling. step-by-step processing then:
The first step: rotor cylindrical car is removed about 0.10mm;
Second step: the solution that hydrochloric acid and water is made into 1: 1;
The 3rd step: handle the rotor outer round surface with hydrochloric acid soln, all brushing;
The 4th step: with the rotor that all brushed on the surface, put into baking oven and dry, the time is not limit.
The rotor of treated mistake was a Minimum Time Limit l with 1 hour during oven dry.
The purpose of treatment process mainly reaches and erodes rotor surface owing to the aluminium that turning is pressed in the iron core is considered to be worth doing, and the aluminium that links to each other with rotor slot palpus, increases the contact resistance between cage bar and iron core.
