- 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
Nice explained.. sir any other causes of submersible winding burst?
You have satisfied my curiosity sir
1.Can loose end covers lead to 3 phase winding short failure?
2. What happens when earth is not connected and overload occurs
Pls do reply
good explanation,
but how to know the right amount of lubrication?
ans secondly to avoid 51% damages due to bearings?
The instruction manual for any motor gives strict and detailed guides to lubrication and varies a lot so not one answer .
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.
Shaft bend happen when Shaft worn out and was repaired by putting a sleeve instead of welding.
nice images in the presentation
Nice explanation of windings damaged
Why do electric motor break?

Hmm idk why
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.
True but magnetic is expensive and repair cost also. Single raw Ball bearing is cheap and easy to replace.
@@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.
thanks sir
