If there is a loose connection, you might show a proper voltage, but when it is under a load it will drop. An error in winding data that results in lower-than-design-level magnetic flux also can cause high current with load. If all of that checks normal, you might have a partial ground in the winding. From what I can tell this motor offers no provisions for bearing maintenance other than to tear it apart and replace them, however, it's not excessively noisy and it takes several seconds for it to run down to a stop after power has been disconnected. It provides 125 PSI with its impressive motor while keeping the noise level reduced. One may also ask, how many amps does a 12v air compressor draw? I know my table saw seems to have a centrifugal switch that comes into play during startup/shutdown, but I haven't heard anything similar from the compressor.
