All,

I'm using a 50Hz, 3000rpm 1/12th HP Teletype sync motor on 60Hz,
for 3600rpm in a rotary sync gap.  I tried connecting a 7uF to 30uF,
cap across the blue and red wire for starting, but it won't start this
way.  Yellow and blue are connected to the line.  I then touched the
red and blue wire together with no cap for starting, this works better,
but the motor still often needs a push to get going, and it makes
clanking noises as the speed ramps up.  Once it reaches max
speed, I disconnect the red wire, then it locks up fine.  I've been 
using this rather awkward method for starting it.

I realize that Teletype motors usually use an external relay block
for starting, but different motors seem to be wired a little differently?

I wonder if the 60Hz on a 50Hz motor makes the starting a little
more difficult?

Does anyone have any suggestions or knowledge of the correct
way to start this type of motor?  Or maybe the motor has an internal
defect?

Thanks,
John Freau
