Motor's energy saving and remanufacturing technology

What is the energy-saving motor remanufacturing it is inefficient motors through redesign and replacement parts and other methods, to create high efficiency and is applicable to the specific load and the condition of the energy-saving motor system, such as changing of motor, frequency conversion motor, permanent magnet motor.

With the promotion of high efficiency motor and motor system energy saving transformation work, the elimination of inefficient motors become more and more. How to deal with these old motor becomes a problem, if the the motor after simple renovation after re entering the market, then the government subsidies, motor, on the promotion of high efficiency motors and motor energy-saving system serious adverse, so inefficient old motor efficient remanufacturing is the inevitable requirement of the national energy-saving emission reduction work. Next, we'll take a look at the process of motor in the motor remanufacturing.

Motor manufacturing process: old assessment of detection and classification, to determine the remanufacturing scheme, the various parts of the dismantling and manufacturing (stator, rotor, end cover, a fan, a wind cover, junction box), assembly, factory test.

Stator:

Stator coil by impregnating insulating paint and a stator iron core curing as a whole, it is often difficult to disassemble, in previous motor repair by fire coil method remove insulative paint, destroyed the core quality, pollution to the environment; remanufacturing using a special machine to cut the ends of winding, non-destructive, non polluting. After cutting winding end by hydraulic extrusion belt coil of stator core and core are heated, out of the stator coil, under the new scheme to re wound coils. After cleaning the stator core, the assembly line, wiring, the pressure test, after passing into the VPI dip paint dip paint, paint and then enter the oven drying.

Rotor:

Using hydraulic puller disassembling bearing; rotor core and a rotating shaft between the interference fit, in order not to damage and core, remanufacturing the intermediate frequency eddy current heating equipment heating to the appearance of the rotor, according to the shaft and rotor core heating of the different thermal expansion coefficient, separation axis and rotor core. After the rotating shaft is processed, the rotor core is heated by an intermediate frequency eddy current heater, and a new shaft is pressed into the rotor core. After the rotor pressure is installed in the dynamic balancing machine to do the dynamic balance detection, using the bearing heater to heat the bearing, mounted to the rotor.

The base and the end cover:

The base and the end cover after passing inspection by sandblasting processing equipment appearance, reuse

Fan, fan cover:

The original parts scrap, the new purchase of efficient fan, wind hood

Terminal panel:

Junction box, wiring board scrap, re purchase. After the connection box seat is cleared, the connection box is re assembled.

Assembly:

A stator, a rotor, a frame, an end cover, a fan, a wind cover and connection box and manufacturing complete, in accordance with the new motor manufacturing methods of the general assembly, then the factory test.
