I work at a place right now that makes motors, and motor-based timers.
These days all the motors are imported from Asia. There's a great
bookshelf in the lab that has all the old classic 'electric motor'
textbooks. A rather dusty shelf, I might add.
This is also the place that uses a Commodore SX64 to test electric
water-valves, incidentally.

AFIK there's no basic difference in the two types but they do have
different voltage and capacitance ratings. Dig up one of the OLD
electrical machinery text books from the 40s or 50s. They usually had
good descriptions of that kind of thing. the modern text books don't
say crap about motors.

Yeah, I'll give you a primer on the
capacitors on the TU56.... to

I'll get to refurbing my TU56
"Someday".
I hope to bring my TU56 back to life this year too ...!
One note on the ### motor capacitors.
AFAIK there is a difference between motor *start* caps and *run*
caps. If I am wrong I would like to know, else what is the
difference?
