Key Features

Balanced Motor Performance: 0.68 Nm rated torque (1.5 Nm peak), supporting reliable positioning with speeds up to 1000 rpm (analog signal control).
High-Resolution Encoder: 20,000-line encoder delivers ultra-fine 0.32 arcsec resolution, with an optional 1 Vpp output available for enhanced resolution capabilities.
Precision Repeatability: ≤ ±1 arcsec ensures consistent, repeatable positioning accuracy for critical manufacturing and measurement tasks.
High Load Capacity & Rigidity: At 5 bar supply pressure, it supports 806 N max axial load and 420 N max radial load, paired with 402 N/µm axial stiffness and 205 N/µm radial stiffness, ideal for heavier payloads.
Exceptional Runout Control: Both axial and radial runout are less than 0.8 µm, guaranteeing superior rotational alignment and true-running performance.
Cost-Effective Operation: Low total air consumption of just 16 NL/min, making it an economical choice for continuous, high-volume use.
