Hello,
this motor is a three phase induction motor where the third is supplied
by a phase shifter condenser. This makes a unsymmetrical revolving
magnetic field with 90 + 90 + 120 degres phase angle. This unsymmetry
reduces efficiency, but no three phase suply is needed. It seems to be
made according to european usage:
green-yellow = protective ground (earth)
blue = neutral, i.e. 0 V ~
black = phase (100 V~ in this case)
red = condenser 4 Microfarad 200 V~ as indicated, the other condenser
lead is to be connected to either blue or brown depending on the sense
of rotation desired.
Don't rely on your DC measurements, red and black are surely not a zero
ohms connection. Put a low power light bulb in series with the supply
source for testing to make sure there will be no short circuit.
Good luck!

a friend gave me this gear motor
he knows nothing about it and i can not find a wiring diagram
i have confirmed with an ohm meter that the yellow and blue wires are
connected and the red and black wires are connected
any ideas
