The common malfunction and expel the three-phase asynchronous motor

Pick to:People's Daily life cannot leave the use of the motor,the production,220v ac electric motors in the using process of www.dongfeng-motor.com the motor has a lot of attention and requirements,may cause significant safety accident.Therefore,how to timely diagnosis permanent magnet motors for sale and troubleshooting,prevent accidents,ensure the safe,reliable and efficient operation of motor,is particularly important for enterprises.Motor fault types,is more complex,can be summarized as two aspects of mechanical and rotor and stator electrical,machinery has swept

chamber,vibration,overheating and damage to the bearing fault; Electrical failure of the stator

windings without phase operation,the reverse of the stator winding unbalanced three phase

current,short-circuit and ground heating winding and rotor winding fault,open circuit,etc.The

analysis in this paper,the commonly used motor fault problems,some one motor fault diagnosis and

maintenance and repair measures.
