The machine after the installation commissioning,if found e.numerical,vibration more than should which to play?

(1),the rotor balance not nuclear good;(2),rotor balance quickly loose;(3),a shaft bending deformation;(4),the coupling center not nuclear is;(5),bottom screw loose;6,installation foundation uneven or solid.(1),magnet prices grease brand not appropriate;(2),grease quality is not good or bad;(3),grease in the bearing chamber,too little or too much;(4),grease with sundry; (5),the rotation part and stationary part;6,bearing inner ring or outer ring;All landowners,bearing
type is wrong,or the electric motors 12 volt quality is bad;Today,of the coupling;Pet-name ruby,belt pull too tight;

Attending,motor vibration is too large.Motor rotor in the process of production,due to the influence of various factors (such as uneven material casting porosity and shrinkage cavity,parts of the weight of ac electric motors error and machining error,etc.) will cause the imbalance of rotor in weight,so the rotor in the assembly after the completion of the school to balance.More than six pole or rated speed is 1000 RPM the motor and motor) under its rotor can be only static balance,balance the other motor www.facebook.com/dongfeng.motor rotor to the school.
