When I was a kid, I took apart my share of clocks and/or clock radios.

They all had the same basic mechanism.  It was a shaded pole motor with a 
semi sealed unit that included the first layer of gears.  I never took apart 
one of the units.  I assume the rotor had a permanent magnet so it would run 
synchronous to the line frequency.

That was 50 years ago.

These are my opinions, not necessarily my employer's.  I hate spam.
