Direct Drive. 1)Simplicity: only one moving part. 2) No backlash because there is no ball screw, or couplings. 3) Non-Contact: so there is no metal to metal contact. 4) Smoothness: minimum vibration and noise. 5) High Axis speed. 6) High Axis Acceleration. 7) Maintenance: just about maintenance free. 8) Life Expectancy: the life expectancy can be indefinite. 9) Accuracy & Repeatability: high accuracy when coupled with linear glass scales.
