Description
xSJ-V11-09T (Mitsubishi Electric)
There is no widely separate “SJ-V11-09ZT” standard motor listing distinct from SJ-V11-09T in Mitsubishi documentation. In practice, SJ-V11-09T and SJ-V11-09ZT are the same motor family, where:
- T = through-spindle type
- Z = internal design revision / updated version (variant code used in OEM builds)
So your code:
SJ-V11-09T / SJ-V11-09ZT → same 5.5 kW SJ-V spindle platform, with 09 (higher torque class) configuration
🔧 SJ-V11-09T — Key specifications
From Mitsubishi SJ-V series official tables:
| Parameter | Value |
|---|---|
| Series | SJ-V |
| Continuous rated output | 5.5 kW |
| Short-time rated output | 7.5 kW (30 min) |
| Acceleration/deceleration output | 7.5 kW |
| Actual accel/decel output | 9 kW |
| Base speed | 750 rpm |
| Maximum speed | 6000 rpm |
| Frame size | A160 |
| Continuous torque | 70 N·m |
| Inertia | 0.0575 kg·m² |
| Radial load capacity | 2940 N |
| Mass | ~110 kg |
| Cooling | External fan / machine-integrated |
⚙️ What “09T” means
- 09 → higher torque winding / heavier-duty version of SJ-V11 frame
- T → through-spindle (hollow shaft for coolant/tool-through)
So:
09T = high-torque 5.5 kW SJ-V spindle optimized for heavier cutting loads
⚙️ What “Z” adds (SJ-V11-09ZT)
When you see ZT instead of T, it typically means:
- Z = revised electrical/mechanical design version
- Same performance class
- OEM-specific update (not a separate power class)
So:
09ZT = updated/optimized version of 09T, same core specs
🏭 Typical applications
SJ-V11-09T / 09ZT is used in:
- CNC vertical machining centers (medium-duty)
- milling machines
- general-purpose machining spindles
- production machining lines
It is chosen when you need:
- ⚖️ balanced torque + speed
- 🔩 better cutting stability than 01T version
- 🏭 continuous industrial operation
⚖️ Position in Mitsubishi spindle lineup
| Series | Role |
|---|---|
| SJ-V | General-purpose spindle motors |
| SJ-VL | Low-inertia tapping/drilling |
| SJ-DG | High torque heavy cutting |
| SJ-DL | Ultra high-speed spindles |
🧠 Simple explanation
SJ-V11-09T (or 09ZT) is a 5.5 kW-class CNC spindle motor designed for stronger cutting torque than entry SJ-V models, suitable for general machining centers up to ~6000 rpm.
