⚙️ What “VL” means
- SJ-V → standard general-purpose spindle motor
- SJ-VL → low-inertia, high-response version of SJ-V
So:
VL = faster acceleration + better performance for tapping/drilling cycles
⚙️ What “02FZT” means
- 02 → 2.2 kW short-time rating class
- FZ → design revision / configuration variant within VL family
- T → through-spindle (hollow shaft) for coolant or tool-through machining
So:
02FZT = standard 2.2 kW VL spindle motor with through-spindle capability and revised design
🏭 Typical applications
SJ-VL11-02FZT is used in:
- CNC tapping machines
- high-speed drilling centers
- compact machining cells
- fast cycle production machines
It is chosen when you need:
- ⚡ very fast start/stop response
- 🔁 high repetition cycle machining
- 🎯 precision drilling/tapping at up to 15,000 rpm
