Thanks for all the answers!
Does that mean this motor does not support variable field, it must be constant?
So the motor must not be "cold" for it to run in S3? I suppose there should be a temperature sensor on armature wired up to the motor driver? (in this case there isn't one).
Hi,
we have some old Siemens DC motors that have nameplates like the following (see attached image), here I state some of the stats:
102V 83A 3000rpm 7.4kW
200V 48A 6000rpm 7.4kW S3->20%
Field:
500V 0.42A
We are looking for appropriate DC drivers. I have some trouble understanding the nameplate...
