The failure phenomenon:motor temperature rise too high or smoke

Reason and solutions:1.Under the heavy load or frequent starting,lighten the load,reduce the starting times 2.During operation phase - wholesalemotor.blogspot.com check the line,recovery phase 3.Stator winding connection errors - check and correct them 4.Stator winding grounding,turn or interphase short circuit - detect grounding or acmotortrading.blogspot.com short

circuit,to repair them 5.Cage rotor winding -- change the rotor broken bar 6.Wound rotor winding short phase operation,find out the fault point,to repair them 7.Brush - check the bearing

single phase induction motor of the stator and rotor,rotor deformation,whether for

repair or replacement 8.Poor ventilation,check whether the small electric fan motor

wind pass unimpeded 9.Voltage is too high or too low,check the reason and ruled out.
