Servo Motors
Servo Motors
(OP)
Hi guys.
I have a small machine and it is powered by stepper motors, but it lacks power.
I want to start using servo motors but the problem is i dont know how to use them. What i want to know is how they work and do all servo motors need a feedback system. Plus how are they controlled, is it by plc?. How much would a servo system cost which has about 100Watts of power? IS there a wesite which describes servo motors in detail?
Thanks guys (sorry if i sound stupid, i haven't studied electricity and electronics in great depth.....yet)

RE: Servo Motors
Will a servo mechanism be a better choice than the stepper motors?

etc. for more info. Please, notice that the servo motor applications can get fairly involved. This may or may not be your case.
What about a higher HP rated step motor?
RE: Servo Motors
A servo system is going to cost 30 - 40% more than a stepper system. Typically the cost is going to be in the motor and cables. I would say your looking at ~$2K for a GOOD simple indexing system.
There are many sites out there. You can get some from mine, www.aerotech.com or www.motionvillage.com there is a nice section on servos.
