Closed loop Step Servo Drive Driver 2HSS86H + 4.5N.M Motor + Encoder

HI Jonathon

would that be the same problem with a servo as a spindle or just these type steppers. I was considering options for slower cutting speeds for stone, and i can not find a reasonably prices spindle that has the torque at lower speeds,

Normally servo motors have a constant torque rating up to a particular speed - often 3000rpm. For the stepper motor system that speed will be lower, however you can't really make a decision without comparing the available systems. Work out what torque vs speed curve you require, then just look which type of motors gets it for the least money.
