Spindle Drive Inverter – OKUMA MIV22-3-V1
The MIV22-3-V1 is a spindle drive inverter (“Motor InVerter / Spindle Drive”) manufactured by OKUMA, documented as a power and control module for the AC spindle motor in OKUMA CNC machining centres and lathes equipped with the proprietary OSP (Open System Platform) control system. The unit manages frequency and voltage conversion to the spindle motor, receiving speed references from the CNC via the OKUMA proprietary bus. Identified by part number MIV22-3-V1 (internal stock code MIV223V1); the prefix MIV stands for “Motor InVerter” in OKUMA nomenclature.
The spindle drive is the electronic converter that transforms the AC mains supply into variable voltage and frequency for the spindle motor, enabling continuous speed regulation as commanded by the CNC program. It is a critical component of the OKUMA drive architecture: failure renders the spindle completely inoperative, causing immediate machine downtime and preventing any machining operation from being carried out.
OKUMA Corporation is a Japanese manufacturer founded in 1898 and a world leader in CNC machine tools and proprietary OSP (Open System Platform) control systems. OKUMA designs and manufactures both machines and controls in-house, ensuring full integration between mechanics and electronics. Components in the MIV series are legacy / discontinued: available exclusively as original spare parts from remaining stock or through specialist repair and spare-part channels.
