One thing that is typically overlooked is how spare motors are stored. Over time, moisture, dirt, dust, and even general vibration from other sources can have a negative impact on the electrical and mechanical condition on the stored motors.
An introduction to Motor Circuit Analysis (MCA) how to utilize MCA to evaluate the overall health of an electric motor as well as discuss why it is important to develop a motor testing program.
There are several different technologies that can be used, alone or in combination, to monitor the condition of your machinery from a predictive maintenance (PdM) perspective. The criticality of the machine affects the number of such inspection-type technologies that are applied to a given failure mode. The more critical the machine and the more critical the failure mode, the more redundancy you will want in the inspections.
Electrical Signature Analysis (ESA) is an energized test method where voltage and current waveforms are captured while the motor system is running to assess the health of the motor system..
Studies show that 83% of electrical winding faults are between conductors. Motor circuit analysis (MCA) is a simple 3-minute non-destructive test that exercises..
