Description
SJ-V15-01ZT is a Mitsubishi Electric SJ-V series AC spindle motor, designed for general CNC machining applications requiring higher spindle power and stable cutting torque.
This model is confirmed as part of Mitsubishi’s medium-inertia SJ-V spindle motor family.
🔧 SJ-V15-01ZT — Key specifications
| Parameter | Value |
|---|---|
| Series | SJ-V |
| Continuous rated output | 11 kW |
| Short-time rated output | 15 kW |
| Frame class | Medium spindle frame (A112/B112 range depending on machine build) |
| Continuous torque | ~47 N·m class |
| Max speed | typically 8,000–10,000 rpm class (machine dependent) |
| Inertia | Medium (higher than SJ-DJ / SJ-DL, lower response than them) |
| Cooling | Machine-integrated / forced air depending on setup |
| Protection | IP44–IP54 (variant dependent) |
⚙️ What “01ZT” means
- 01 → standard design revision
- Z → internal design optimization variant
- T → through-spindle (hollow shaft) configuration for coolant / tool-through machining
So 01ZT = standard SJ-V 15 kW-class spindle with through-spindle capability and revised design version.
🏭 Typical applications
SJ-V15-01ZT is used in:
- CNC vertical machining centers
- medium-duty milling machines
- production machining lines
- general-purpose metal cutting spindles
It is chosen when you need:
- higher torque than SJ-V 2.2–7.5 kW models
- stable heavy cutting performance
- reliable continuous industrial operation
⚖️ Where it fits in Mitsubishi spindle lineup
| Series | Role |
|---|---|
| SJ-DL | Ultra high-speed (tapping/drilling) |
| SJ-DJ | Compact/lightweight spindles |
| SJ-V | General-purpose spindle motors |
| SJ-DG | High torque / heavy cutting |
🧠 Simple explanation
SJ-V15-01ZT is a 15 kW-class CNC spindle motor designed for general machining centers, offering strong cutting torque and stable operation rather than ultra-high speed or ultra-light response.
