MDS-B-SPJ2-55 – Mitsubishi CNC AC Spindle Drive Unit (5.5kW, 200–230V)

The MDS-B-SPJ2-55 is an AC spindle drive unit manufactured by Mitsubishi Electric, designed for CNC machine tools that require stable and precise spindle speed and torque control.

This spindle amplifier operates on three-phase 200–230 V AC and delivers a rated power of 5.5 kW, making it suitable for medium-power CNC machining applications. It is commonly used in machining centers and CNC lathes where reliable spindle acceleration, deceleration, and load response are essential for machining accuracy and surface quality.

The MDS-B-SPJ2-55 is part of the Mitsubishi MDS spindle drive series and remains widely installed in existing CNC systems. Proper maintenance or timely replacement of the spindle drive is critical to avoid spindle alarms, speed instability, or unexpected machine downtime.

REACO CNC provide sales, replacement, and professional repair services for Mitsubishi CNC spindle drive units, supporting both legacy and active CNC installations worldwide.
