[CQ-Contest] Rotor indetification

[Peter]

Hello,

I need your help to intentify our rotor.
Via friend we have had a huge rotor. The weight is about 20 kilos and
the diameter of the house is around 40 cm. This is a heavy
(proffesional) one. There is no control unit here

The name on it is Wilhelm Winter Ratingen. So I think its from germany.
In the rotor there is a very nice worm geared motor (also heavy!)
There is no readout feed back unit in the rotor Just two end switches to
prevent more than 320 rotation.

The motor is a DC type Its made by Bosch and has the follow marks:
Bosch  GJ12
0 390 116 514

There are 3 places to feed the voltages to and the house is also use as
a point for it .

Now the question: What kind of voltages is needed by the motor. It
running on 12 V but not very fast. Can try more but no spare parts!

I have tried to concact Bosch but no luck till now.
Also a seach on the rotor did not sucseed.
