Vibration Motor Common Failures and methods: (a) vibration motor power is turned on, the vibration motor can not turn a stator winding phase short circuit, open circuit ground and two stator windings, stator winding wiring fault 3, overloading or jamming a) Check to find open circuit, short circuit to ground sites, the implementation of repair b) Check the stator winding connection, be corrected c) to reduce the load or remove jammed material (b) vibration motor is running below the rated speed of a motor broken rotor 2, replacement of cast aluminum rotor three) vibration motor bracket breaking a leg, no bolt tightening bolt tightening --- 2, and feet flat with - reworked two planes to reach a good agreement (four) www.zhendongpingtai.com vibration motor temperature rises too high or smoke one, overloaded 2, breaking three rotor windings, stator winding connection error 4, the stator windings shorted to ground or phase 5, 6 broken rotor, stator and rotor rub one phase to reduce the load 2 , detect open circuit position, to be repaired 3. Check the stator winding connection, be corrected 4, found the site to be shorted to ground and repair 5, replace aluminum rotor 6, check the motor air gap, counterweight and bearing wear, etc. (five) charged a vibration motor housing, poor grounding or earthing resistance is too 2 3 winding insulation damage, winding damp 4, the inner surface of the ground plane is damaged or too much grease 1, identify the causes and take the appropriate measures 2, repair the insulation, and to deal with three dipping, drying or drying impregnation 4, replace or remove the grounding plate (six) a vibration motor bearings overheating, excessive bearing wear or quality problems 2, bearing grease too much or too little, model selection or improper poor quality 3, the bearing inner ring and the shaft with too loose or too tight 4, bearing outer cover fit too loose or too tight five, both sides of the assembly cover and sides of the bearing cap and bearing a non-parallel, replacement of bearings 2, adjust or replace the bearing grease 3, when too loose can be sprayed layer of metal on the shaft can be reworked when tight shaft 4, after the bearing bore can be expanded when the end cap is too loose casement, tight time can be reworked bearing bore www.hnzddj.net 5, will cover both sides of the bearing cap fitted or flat, then tighten the bolt
