Motor Problems Are solved. It's all about Control now.

[dArsonval]

Having worked on electric motors for a little while. An observation is continually noted.
It's all about how (they) are controlled. The motor itself has been made to perfection.
If the motor fails, it's not the motor's poor design, it's the way it was controlled, or it's application.

And not to forget poor manufacturing also contributes to early failures.

The design intent might be OK, but there are still many motor available that not even close to being made to perfection.

Bearing failure due to improper greasing or lack of grease.

The demand for high performance electric motors for electric vehicles means there are plenty of applications outside the range of standardized IEC or NEMA induction motors that are yet to be designed or applied. Further demands for such motors to be built without rare-earth materials adds another interesting constraint.

I think John may be dangling a baited hook.

I guess it depends how you define 'perfection', but I don't think we're there yet.

'Perfection' would be maintenance-free, corrosion-proof, with unlimited operating life. Terminals should be tool-less and should accommodate all cable shapes and sizes. Rotation should automatically be the desired direction, regardless of phase sequence. If I could add in the motor needs to be lossless that would be great, and could you make them cheap too?

Ha-ha, I think you'll be making a living for many years to come.
