Actually, I think Ametek makes that motor in a servo version. There should be some identical ones on Ebay with encoders selling for about $150.00 each. That might be that guy's secret. Yes I think it would work just fine. One other thing to look for in a motor is timing. If the motor has slightly advanced or retarded timing, it will perform differently in forward than it does in reverse. This is very bad for a servo. Many motors made for certain applications will have their timing advanced a couple of degrees. Obviously this is only an issue with brushed motors. I think pretty much all brushless motors are servo grade. |
