Description
SJ-V2.2-01T is a Mitsubishi Electric SJ-V series standard AC spindle motor, used in CNC machines for general-purpose spindle drive applications (cutting tool rotation in machining centers).
It belongs to the SJ-V spindle motor family, which is a conventional/high-performance spindle series (not low-inertia like SJ-DL, and not high-torque like SJ-DG).
