Recently, Sears has been emphasizing that their lighter duty air
compressors have universal motors. Is this a good thing? I've read that
UMC motors allow extension cord use, provide higher startup torque and
are lighter in weight. But, does all that come at the cost of long-term
durability vs. an induction type motor?




Universal motors are loud and obnoxious, and the brushes need replacing
occasionally. Their one good characteristic is they will run on DC
power (got any 120V DC outlets?)
