Description
SJ-V11-01T (Mitsubishi Electric)
SJ-V11-01T is a Mitsubishi Electric SJ-V series AC spindle motor, used in general-purpose CNC machining centers for light to medium-duty spindle cutting operations.
It is one of the entry-level power variants in the SJ-V spindle family, designed for balanced torque and speed (not ultra-high-speed like VL/DL, and not heavy-torque like large V models).

⚙️ What “01T” means
- 01 → standard design / configuration
- T → through-spindle (hollow shaft) type (coolant / tool-through capability)
So:
01T = standard SJ-V spindle motor with through-spindle configuration
🏭 Typical applications
SJ-V11-01T is used in:
- CNC milling machines (light-duty)
- drilling and tapping machines (general use)
- small to medium machining centers
- production machines requiring stable but not extreme torque
It is chosen when you need:
- stable general machining performance
- moderate torque at low RPM
- reliable continuous industrial operation
