Key Technical Notes
- Industrial Heavyweight: At 110 lbs, this motor requires robust mounting structures. The high inertia is essential for stabilizing massive mechanical loads like large-scale CNC bridge mills or heavy industrial presses.
- Shaft Design: Features a reinforced 42 mm shaft with a keyway and oil seal to handle the high torque output without shearing or leaking in oily environments.
- Safety: The built-in brake is designed to hold the 47.74 Nm rated load securely in the event of a power failure.
