    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.

    General Guidelines for Failure Analysis · PDF Datei

    Rotor Failure Modes The following failure modes can occur on a progressing cavity pump rotor: Abrasive Wear: Abrasive wear occurs when the hard chrome plating on the rotor becomes worn. This wear can be just on the surface of the chrome or down to the base metal. In either case, the original rotor profile is changed. This change in profile can affect the pump's performance in that the ...

    Detecting Broken Rotor Bars Prevents .

    Broken rotor bars (Fig. 1) rarely cause immediate failures, especially in large multi-pole (slow-speed) motors. However, if there are enough broken rotor bars, the motor may not start as it may not be able to develop sufficient accelerating torque. Regardless, the presence of broken rotor bars precipitates deterioration in other components that can result in time-consuming and expensive fixes.

    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.

    These crushers use a high speed rotor that has its axis along the vertical axis. The vertical-shaft impact crusher can be considered a stone pump that can operate like a centrifugal pump. The material is fed through the center of the rotor, where it is augmented to high speeds before being cleared through openings in the rotor sideline. The material is crushed as it hits the outer body/ anvils ...
