There are a few reasons, but this one normally gives you an indication.
Ok, lets say you have a machine with 8 axis and each axis needs a servo, that is not too large.
you can get 8 AC servo motors and driver and you will be paying more because each driver has its own power supply.
with the DC option, you will have 8 DC servo drivers and a large power supply.
Also DC servo motors are typically low voltage DC, so the current is higher, so typically the motors dont go too big (under a KW)
Personally, i would not even consider a DC servo system, unless you know why you need it. AN ac servo system is typically a better option.

it totally depends on what the bus voltage of the motor is.
To make it easy, if and when you buy them get a matched pair with cables, or talk directly to the company and get advise on what they suggest for the application.Visit Us: www.automationshop.co.uk

10-07-2017 #28OK, so just to be clear. A 400W AC servo motor would typically be coupled to a driver powered by AC at a voltage less than 240v?Gerry

What do you think of this: http://www.ebay.co.uk/itm/Samsung-RS...-/282340382590
Might it be suitable for my app or am I barking up the wrong tree?
