DC motor controller 24 V, 30..50 A

I'm looking for DC motor controler,
24 Volts, 30 .. 50 A.

A PC should control the absolute position
of the angle of the motor.
I'm not sure, but I think in general this is called a servo system.

In the past this motor was controled by a linear amplifier.

I can find a lot controlers that connects directly to the mains,
and then switches back to 24 Volt (or less),
but for safety reasons I can not use these.

Has anyone links to dealers or manufactures of such controlers ?

thanks,
Stef Mientki
 
do you've a p\n ??
probably i can help you !!

This is indeed a servo system, by my understanding at least. You will
probably want to attach a linear pot to the motor's shaft to get
feedback on its position, although if you want continuous rotation or
very accurate position feedback a shaft encoder might be better.

Is this a normal DC brush (commutator) motor? Is so, a RoboteQ motor
controller (www.roboteq.com) will do what you want but it might be a bit
overspecified and expensive for what you want, these will run two motors
at up to 120amps each. There are many cheaper DC motor controllers
around, have a look at the ones used in Battlebots / Robot Wars, but so
far as I know only the RoboteQ has the position feedback ability built in.

Would DIY (kistrus) 166 be any help? You might need some more cooling,
big wires soldered to the high-current traces, and of course you
should add interlligence, but you are surely up to that :)
