Magnetic stability: Key to avoiding rotor rubs
|
Although an even air gap is impossible to maintain, contact between rotor and stator can be minimized
REBALANCE IT ALL YOU want-no electric motor will ever exhibit zero vibration. Perfection can't be expected. Similarly, no matter how accurate the machining, no motor can ever be assembled with a perfect air gap. Some eccentricity is unavoidable.
Many contributing causes exist besides machining tolerances. Rotor/ shaft weight inevitably causes the shaft to sag. Bearing clearanc...
