I want to drive an old 1/2 HP, 230V armature, 200V field DC brush motor, previously driven by an amplidyne [we are talking about 1960 stuff]. I have found many SCR analog drives suited for 180V armature, 1/2 HP, many of them also supplying the field voltage.
I wish to close the position loop using an encoder, however I cannot find a digital drive with the same specifications. Therefore I have two questions:
1. Can I use a separate motion controller, feed the +-10V to the SCR analog drive, and get decent response after a bit of tuning?
2. Is there any digital drive for this kind of motor? If not, why [i.e.: is there a technical reason, or just there is no demand]?
Thanks,
Mark
