help with motor

[James]

anyone able to help me with this motor?

its a dc motor with forced vent.

i am trying to find a suitable motor drive for it but the nameplate is confusing me.
anyone fancy deciphering it for me?

From what I found out online the G and N mean direct current, shunt. The A is to do with ventilation, the rest no idea. Try contacting Baumueller.

What's this motor going to be fitted in, they seem to be mainly used in Plastic injection moulding machines?

These are the DC drives for them;

Servo drive for automation and motion control

Thanks guys,
This is for a large surface grinder.

Armature voltage, current, power, speed self explanatory.
Shunt wound. Err. = Erregung = excitation, 190V 2.8A
Schwinggüte SR = vibration class SR but I can't recall which EN this relates to.

so
130-400v is that a range? I am used to seeing max voltage shown on nameplate but never a minimum.

94-94 in A box is max current for any voltage?

suggests to me that the obscured part should read 10-34Kw

thanks for the err. didn't know that was the excitation voltage, but it makes sense now you have pointed it out.

basically it looks like a standard 3 phase 2 or 4 quadrant drive rated for 100A should suffice.

Thanks for everybody's input.

Yes, 94A at any armature voltage in the range 130-400V. i.e. constant max torque over 10-34kW output. I think the point with the minimum voltage is that the minimum rated speed (possibly specified by the machine makers) is 1000 rpm, and that is the voltage needed to achieve that speed. At lower speeds it might fall out of spec for torsional vibration etc.
