PRODUCT DESCRIPTION
OKUMA MDUA-22-422-M - AC Spindle Motor
The OKUMA MDUA-22-422-M is a three-phase AC spindle motor engineered for high-precision, high-speed material removal applications in industrial environments. This component integrates into OKUMA CNC machine tools, providing the primary rotational power for machining operations through vector control via a dedicated spindle drive. It is specifically designed for demanding applications such as milling, turning, and grinding on CNC machining centers and lathes.
