Has anyone else experienced motor failures due to water intrusion?
This tunnel has 16 motors driving various brushes, mitters, etc. We have replaced 8 in the last 3 years since new and they continue to fail - sometimes multiple failures in the same equipment.
AVW uses the Sumitomo gearmotor with a 22:1 reduction. That motor package, according to Sumitomo, is rated IP55 which is not wash-down rated. Further, AVW replaces the factory conbox with a different box to make clearance in the mounting frames of the equipment. It seems there are multiple point of potential water ingress.
Since last year, when installing a new motor, I pack the conbox with dielectric grease to abate water intrusion. This has been successful for the most part but we had one failure regardless.
Anyone else out there with this experience?
P.S. AVW has discontinued this motor in the newer equipment in favor of an SEW-branded setup that does not fit in the same space as the Sumitomo. Further, they still sell the replacement Sumitomo but with no warranty. How can a company legitimately sell a known defective-designed product and claim no responsibility?
