Rated Torque: 28.4 N·m; Peak Torque: 71.1 N·m (250% short-time overload capacity)
Rated Current: 16.5 A; Peak Current: 40.5 A
Power Supply: 3-phase AC400V
Encoder: 20-bit high-resolution serial incremental encoder (1,048,576 ppr)
Brake: Without integrated DC90V electromagnetic holding brake
Shaft Oil Seal: Not equipped, only suitable for clean dry indoor environments

Only compatible with Yaskawa 400V Sigma5 series drives:

SGMGV-44DDA6F: No brake and no shaft oil seal, lower cost, applied to horizontal axes or vertical loads with external locking devices
SGMGV-44DDA6H: Built-in DC90V holding brake plus shaft oil seal, ideal for machine tools, environments with cutting fluid mist and vertical heavy lifting axes

Medium inertia rotor delivers stable operation during frequent start-stop and reciprocating motion, outstanding dynamic performance under heavy loads
20-bit ultra-high resolution encoder ensures superior positioning accuracy with low low-speed cogging
400V high voltage design reduces operating current and allows long-distance cable wiring
Brake-free structure shortens motor overall length to save installation space on equipment
250% short-time overload torque meets rapid acceleration and deceleration demands of heavy-duty machinery

Horizontal feed axes of CNC gantry machines and heavy-duty lathes (no power-off self-locking requirement)
Heavy-duty conveying and sorting horizontal axes for packaging and printing equipment
Heavy-duty gantry handling and horizontal transfer automation equipment
Horizontal servo drive axes for plastic extruders and injection molding machines
Automated production lines in clean dry workshops free of cutting fluid and oil contamination
