The only advantage the wound rotor motor offers is during start up of high torque applications. External resisters are used in the rotor circuit to limit starting amps in the rotor. Once the wound rotor motor comes up to speed all external resistance is shorted out and the motor performs like...
I dont know the answer to your question, but will offer this comment to perhaps help solve your problem. The problem is probably not the mag center but probably in the coupling. You never want to couple a motor in such a way that it can contact its thrust, and you use the extruder to hold the...
Several things to consider about doing a retrofil, the "cleaning" agent, or interm fluid used for retrofil is perchlorethane?(or etylene cant remember)this is the same basic thing as dry cleaning fluid used by the dry cleaners. However this fluid is a hazardous wasted and special...
First know that a low power factor is not a good thing, you always want a higher power. Power factor is simply a comparision ratio of real to reactive power. Secondly you need to understand that a larger motor will require a higer starting current, starting current is dependent on lock rotor...
hey duke, if these indications are legitimate I would think it could be a rotor problem, perhaps a break in the rotor bar shorting ring, being that this is a small motor it may be worth while to change it out with a new one and see if the problem goes away, check out what the starting...
Hello bobziva, you might want to put the burden of properly sizing the motor on the compressor vendor and simply issue a minimum of specs. such as, motor enclosure type, operation voltage, bearing type (sleave or anti-friction), widing and bearing rtd, Class F insulation with class B temp rise...
