Todd A. Hatfield, VP of Engineering and Repair at HECO - All Systems Go, goes over common types and causes of failures in electric motors at the 2016 Reliability Process and Maintenance (RPM) Symposium in Kalamazoo, MI
You can see it on the nameplate below. Amount of grease. But normally 3 to 5 stroke is enough every 6 months. But bearing is cheap so change it every year simple and easy.
These electric motors were designed to fail. Why restore a failed design instead of redesigning it not to fail. Ball bearings aren't needed in the complete design. The whole design should be magnetic. Magnetic rotational field should be the only mode of operation.
@@kerblow2017 it doesn't need ball bearings. It can add an extra layer to the magnet field by using magnetic balancing also. An added magnetic blancing/ forcefield.a force within a force.
