SJ-V22-05T (Mitsubishi Electric)

SJ-V22-05T is a Mitsubishi Electric SJ-V series AC spindle motor, designed for medium-to-heavy duty CNC machining centers requiring high torque, stable cutting performance, and reliable continuous spindle operation.

It belongs to the SJ-V medium-inertia spindle motor family, commonly used in industrial milling and machining applications.

🔧 Key specifications (SJ-V22-05T)

From Mitsubishi spindle motor specification tables: (dl.mitsubishielectric.com)

⚙️ What “05T” means

• 05 → winding / torque-speed configuration variant within SJ-V22 class
• T → through-spindle (hollow shaft) configuration for coolant/tool-through machining

So:

05T = SJ-V22 spindle motor with through-spindle capability and specific torque-speed tuning

🏭 Typical applications

SJ-V22-05T is used in:

• CNC vertical machining centers (VMCs)
• horizontal machining centers (HMCs)
• industrial milling machines
• production machining lines

It is selected when machines need:

• ⚖️ high cutting torque at low RPM
• 🔩 stable continuous cutting performance
• 🧱 rigid spindle behavior under load

⚖️ Position in Mitsubishi spindle lineup

🧠 Simple explanation

SJ-V22-05T is a heavy-duty CNC spindle motor designed for machining centers that need strong cutting torque and stable operation up to about 6000 rpm.
