Marklin HO 3 Rail - How Many Volts AC Needed to Turn Over The Motor??

I have an old HO Marklin 0-6-0, 3 rail pickup, & I am wondering how many volts AC are normally needed at the brushes to get the motor turning over?

Thanks

About 10 volts as I recall. The reversing relay needs about 25 volts to operate.

I took the body off & the engineering in these guys is more complex than conventional DC HO. Very interesting stuff under the hood.

So if the motor rolls at about 10v AC, whats the voltage range of the motor, ie, how many volts is it pulling full throttle?

Thanks

About 16, if I remember correctly.

Starting voltage is more like 4-5vac, top end is about 16-18vac, 25vac pulse for rev/for.

Ok, thanks.

Anyone know of a simple way to drop the 17v AC ‘accessories outlet’ voltage off the back of a conventional DC HO transformer down to around roughly 5 to 7 AC, so I can test the engine ?
