Yep all those, Roy.
My only experience of a failed motor had all of those but it went in a oner with the smoke getting out. It was the motor on effectively a home built table saw - actually the saw was supplied without the motor, and I fitted whatever I could find, which was an open ventilation motor with a centrifugal start. So damp and sawdust had full entry.
Every so often a bit of sawdust got across the starter contacts and the motor would just sit there and hum vigorously until I remembered why and hit the off button. It was easy enough the clear - a screwdriver through the end plate and hit the C/F switch, but after 25 years the smoke got out one day.
So I made the failure query with a bit of experience.
Just to finish the story, I had recovered an early pressure washer from a skip about the same time - the saw went from a 600w motor to a 3kw one; wish I had had that all those years of ripping biggish bits of wood.
