Anyone knows where I can rent such a motor?
Should be able to run at 24fps and 25fps.

What about the necessary modificaton to the 400 ft magazine? I suppose this is a
simple resistor in series with the motor, correct? So it could be un-done again afterwards?

Greetings,
Marc

Talked to Clive Tobin about this once, and I think it is a bit more complicated than just putting a resistor in series in the motor to convert the motor to 12 volts. Look around as there were some 12 volt torque motors made by the ARRI factory for the 16St. Being there in Munich, I would recommend talking to the folks at the factory, they should be able to help.

Best,

On our 12 volt conversions, we put in a resistor and one or two capacitors according to motor vintage, and a transient voltage protector diode. Otherwise the torque motor and its blue arcing brushes put out too much static which can upset a crystal motor or even cause damage.

Speaking of our Arri 16-S / 16-M crystal motors, the resurrected TXM-22A might be available in about a month. We have the internal motors and circuit boards now, and the metal parts are being done at the machine shop.
