The Okuma WCHG Winding Changeover Spindle Motors series is a group of machine-specific spindle motors used in Okuma CNC systems for spindle-drive applications that require compatibility with the original machine electrical and control architecture.
These motors are intended for integration with matched Okuma spindle drive hardware rather than for standalone general-purpose motor use. Within the machine system, the series serves spindle functions where controlled speed operation, electrical compatibility, and support for the host spindle configuration are required. Within the machine system, the series functions as spindle motor hardware that works with the matched Okuma drive and control system to deliver commanded spindle speed and torque. Its winding-changeover design is intended to support different operating ranges within the same motor platform, which is useful in machine tool applications that need spindle performance across varying speed conditions.
