There is a good chance, especially if your drives limit the current via
pwm, chopper etc that the 30vdc will be fine.
Check the specs on your drives. Eg Gecko's would more than likely be
fine.

Hope this helps,
David

Subject: [CAD_CAM_EDM_DRO] Transformer question


I will soon be making a power supply for some servo motors. I have a
large transformer that I pulled from a piece of equipment my company
was getting rid of. It produces about 30 volts and judging from the
size of the wires, I think it can supply at least 15 amps. More than
enough for what I need. Unfortunately, the servos that I want to use
are rated at 24 volts, so before I go looking for another
transformer, I would like to ask the group if there is a way to
limit the voltage of this transformer. It seems to me that I
remember seeing circuits that used a zener diode to reduce voltage.
Am I way off base here, or can this be done?

Thanks,
Tom Murray
