Device using a lot of clothing brushless motor, such as DUKEPU, Bedford, heavy machinery and other brands, although the effect of these motors use the whole quite good, but after a certain number of years in use, many motor that comes with a lot of failures. For brushless motor is generally installed in the back-end encoder, encoder, such damage, the general conventional treatment:
First, the wiring is bad; two internal dirty; Third, there is wear the device (including the code disc wear); Fourth, there is damage to small crystal devices; five is the integrated sensor damage.
Through the above conventional treatment can solve 98% of the basic fault. In addition to these failures, the type of motor then there are the mechanical problems, and summarize the general failure of the following:
First, the bearing damage; second rotor problem; third stator winding problems.
Bearing bad can be changed, can be re-burned around the winding, the rotor is damaged, a lot of maintenance staff know what to plant, because these are usually the rotor within the magnetic stripe expansion, resulting bulge out of the metal, resulting in “sweep chamber” problem. So how to handle it?
The way we deal with are: First, remove the outer metal, removing the magnetic stripe (magnetic strip to pay attention to the order, try not misplaced, or re-check a little trouble), clean interior and magnetic stripe itself (be sure to handle clean, conditional You can draw a few prints on the rotor), there are slightly higher at the polished look, alcohol or dry clean pine fragrance. Then, glue (we used a 326), paste the magnetic strip, then glue (we used a transformer plant resin, the specific model unknown), and then paste the glass fiber cloth (optional 0.06mm), gently pull level, so that through the fabric glue. Finally, heat drying (the effect can also be just dry naturally slow, easy flow of glue), and finally is installed debugging.
After the above treatment, the effect is very good, comparable to the new machine, if there is a better way which does not also contribute to what anti-exchange brings progress!
