Yaskawa CIMR-MT II-22K.B AC Spindle Drive System

The Yaskawa CIMR-MT II-22K.B Varispeed 626 MT II AC Spindle Drive System is a panel-mounted AC Spindle Drive that delivers precise spindle speed and torque control for CNC spindles. Built to replace or retrofit legacy spindle drive systems, it shines in CNC lathes, milling machines, machining centers, and metalworking equipment that demand accurate spindle speed control. As part of the Varispeed 626 MT II family, it provides approximately 22 kW (about 30 HP) with a 3-phase input typically 380–480 VAC and an adjustable AC output for spindle motor control, employing high-performance vector control for spindle applications and extended high-frequency output for spindle speeds. It is compatible with AC spindle motors and high-speed induction motors, supporting CNC spindle speed and torque control in metal cutting operations, grinding machines, and automated production lines where stable speed and torque, and rapid acceleration/deceleration are essential. Common replacements include Yaskawa CIMR-G7A4022, CIMR-AU4A0022FAA, and CIMR-AC4A0022FAA.
