The Common Failures of Hammer Crushers JXSC Machine

The rotor system of the hammer crushers is affected by factors such as rotor misalignment, bending of the shaft, looseness of the foundation, wear of the bearing, improper assembly, etc., and friction or even rubbing phenomenon with the bearing. Although the torque that the rotor is subjected to during operation of the equipment can be balanced, the rotational speed is greatly affected, the

Explaining Motor Failure EC&M

Most motor failures are caused by a combination of various stresses that act upon the bearings, stator, rotor, and shaft. If these stresses are kept within the design capabilities of the system, premature failure shouldn't occur. However, if any combination of the stresses exceeds the design capacity, the life of the system may be drastically reduced and catastrophic failure could occur.

Common Causes for Electric Motor Failure Motor Failure

Most of the electric motor failures occur at the start up. Most of them are caused by the over-heating of motor. There are also other factors which greatly affect the performance of electric motors such as low resistance, dirt, moisture, over-current and vibrations. Electric motors should be installed very carefully and should be looked after at regular intervals.

Cause and analysis of stator and rotor failures in three

Abstract: The squirrel cage induction motor has limitations, which, if exceeded, will result in premature failure of the stator or rotor. The authors identify the various causes of stator and rotor failures. A specific methodology is proposed to facilitate an accurate analysis of these failures. Failures of the bearings and lubrication systems are excluded. > Published in: IEEE Transactions on
