Most motors are designed to operate for about 20 years, with proper maintenance, so longevity should not be a problem. However, a large number of motors are not reaching their expected life. At a client, a 2 hp motor, for example, running a conveyor section at a major food producer’s facility suddenly failed, shutting down the line. Water had seeped into the conduit box during washdowns and eventually ate away at the cabling insulation. It cost the company hundreds of thousands of dollars in lost product and production time. Why did this get missed?
One reason was that due to the expense of monitoring equipment, the company had not invested in any predictive monitoring, they had regular preventive maintenance schedules and somehow their existing maintenance schedules had missed the fact that the water had seeped in. Another reason was that there was insufficient knowledge about application effects on motor operation within the maintenance team. Research indicates that 86% of companies using motors, said their motors rarely lasted longer than 5 to 10 years. No one indicated that they had a motor survive to its 15th year. In fact, most were experiencing significant motor failures in the second or third year of a motor’s life, getting about 25% or less of the life designed into a standard motor. The top reasons for such disruptive failure were Bearing failure, motor abuse, grease contamination followed by improper motor installation, most of which could be diagnosed by predictive maintenance review of data. The Ennosys IOT EYE: A Predictive Monitoring Service enables organizations to improve the effectiveness of their maintenance in a non-disruptive manner. Learn how we can view the operating characteristics of a machine in minutes online. The sensors magnetically mount on industrial machinery and broadcast the machine data to the cloud. Our FFT and AI based algorithms then work on the data to diagnose “machine faults” with a high degree of accuracy. Learn how the Ennosys EYE could transform your maintenance operation here
