A replacement for servomac DC Drive

[baba1511]

Please I need a dc drive that will replace a CNC Lathe machine z axis DC Drive PART NO (3ANO1450) PART DESCRIPTION (MAT 1450 DRIVE)
The make is Servomac & the DC Motor spec is
Power 6.8kw
Current 22amps
Tacho 7mv/min
Any help will be welcomed.

If it is analogue control and encoder feedback to the controller, look at Advanced Motion Controls 100A40/100A40AC.

Al, just curious: why not an amc 100A25 instead to save money?

[Al_The_Man]

The 100A40 is the only one that is still active or current item.
The B100A40 will also work just as well, I suspect the difference in price between the 25 & 40 is minimal, also I did not know for sure what the operating voltage was for the Servomac?

The suply voltage is 110vac three phase

the 100a40AC model accepts 110vac input. check it out at a-m-c.comn or on ebay or ask Al_the_man -maybe he sells them??

Thanks Mike
I could not find 100a40AC at -m-c, Al_the_man any further help?

I guess they do not carry them any more? Just the 100A40 which requires a DC supply.
The B100A40AC works just as well with DC brushed motors.

Set the commutation to 60° and use the U V outputs.

Remember too you can buy the dc input one and also buy a small ac->dc power supply from them to run it....
