Description
SJ-DL1.5/100-01 is a Mitsubishi Electric SJ-DL series low-inertia CNC spindle motor, designed mainly for high-speed drilling and tapping machines where rapid acceleration and deceleration are more important than high cutting torque.
This belongs to the SJ-DL (Low-Inertia / High-Speed spindle motor family).

⚙️ What “SJ-DL” means
The SJ-DL series is specifically designed for:
- ⚡ Very fast spindle acceleration
- 🔁 Frequent start/stop cycles
- 🎯 High-speed drilling & tapping
- 📉 Low rotor inertia (key design feature)
It is not meant for heavy rough cutting, unlike SJ-DG or high-torque SJ-D motors.
🧠 Code breakdown
- SJ-DL → low-inertia, high-speed spindle motor series
- 1.5 → power class (1.5 kW short-time rating)
- /100 → compact 100-frame spindle size
- -01 → design revision/version
🏭 Typical applications
Used in:
- CNC tapping machines
- drilling centers
- small machining centers
- high-speed light machining operations
📐 Key behavior characteristics
- Very fast spin-up and spin-down
- Low cutting torque capacity
- Best performance at high RPM
- Designed for productivity (cycle time reduction), not heavy load removal
🧠 Simple explanation
SJ-DL1.5/100-01 is a small, ultra-fast CNC spindle motor designed for drilling and tapping, where speed and quick response matter more than cutting power.
