(1) of the motor shell must make the pledge that we shall have good grounding or zero.(2)

periodically clean the machine work,purging of the compressed air,compressed air diesel

generatorshould be clean and shall not contain water and oil content,pressure should not

exceed 2~3 KGF/cm~2*1 KGF/cm~2 = 9.80665*10~4 Pa (3) the number of motor bearing grease should be stipulated by the original factory,no rules,should be combined with the working performance of the motor selection,filling quantity to be appropriate.(4) brushes,slip ring,or the processing of commutator and brush holder adjustment,must be a power outage.asynchronous motor (5) discontinued for a long acmotortrading.blogspot.com time and after the fault

treatment of motor,must by the insulation test qualified,can put into operation.Insulation resistance

shall meet the handover and the regulation of the preventive test electrical equipment in the

single phase generator regulations.Generally high voltage ac motor stator insulation

resistance should not be less than 1 M per kv ,rotor every 0.5 M kv; Low voltage of the motor stator

insulation resistance should not be less than 0.5 M ,rotor should not be less than 0.15 M.
