4 Examples of Root Cause AnalysisSimplicable

A root cause analysis is a systematic analysis that seeks to uncover the fundamental underlying or initial causes of an incident failure or problem. It is typically intended to manage risks and improve a business by identifying ways to fix underlying issues that allow failures to occur. The following are illustrative examples. The most common cause of motor failure and arguably the most difficult to overcome is low resistance. Low resistance is caused by the degradation of the insulation of the windings due to conditions such as overheating corrosion or physical damage. This leads to insufficient isolation between the conductors or motor windings which can cause

Selecting Inching Drives for Mill and Kiln Applications

The standard inching drive motor is a NEMA or IEC frame typically foot mounted to a motor scoop or base plate. Typical motor speeds are either 4 or 6 pole i.e. 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if Figure 4 The Motor Bearing Fault. Environmental faults in three phase induction motor.
