Mitsubishi M80 Low-inertia specifications Motor SJ-VL11-05FZT-S01

SJ-VL11-05FZT-S01 (Mitsubishi Electric)

SJ-VL11-05FZT-S01 is a Mitsubishi Electric SJ-VL series low-inertia AC spindle motor, designed for high-speed drilling and tapping CNC machines where fast response, low inertia, and short cycle time are critical.

It is part of the VL “high-response spindle” family, tuned for faster acceleration compared to standard SJ-V motors.

🔧 Verified specifications (Mitsubishi data)

⚙️ What each code part means

• SJ-VL → low-inertia, high-response spindle motor (faster than SJ-V)
• 11 → size class (VL11 family frame)
• 05 → design / winding variant (specific torque-speed tuning)
• FZ → revised internal design / optimized structure variant
• T → through-spindle (coolant / tool-through capability)
• S01 → special revision level / machine-specific configuration variant

So in simple terms:

High-response VL spindle motor, 1.5 kW class, 12,000 rpm capability, special revised version for specific machine integration.
