Well, what say we get ahold of a motor & try it out? I really don't think the starting windings will take much abuse & it is just a SWAG that they will burn out before the built in thermal protector does its thing.

I run across this problem with motors on garage door operators. the run time is really short, so the starting windings take a lot of abuse & the thermal overload almost never trips out.

Few things are harder to put up with than the annoyance of a good example.
