Mitsubishi M80 Spindle Motor 200V SJ-D11/100-01

SJ-D11/100-01 is a Mitsubishi Electric SJ-D series AC spindle motor, used in CNC machine tools to drive the main spindle (cutting tool rotation).

It is one of the higher-power spindle motors in the SJ-D lineup.

🔧 Key specifications (SJ-D11/100-01)

⚙️ What it is used for

This motor drives the CNC spindle, meaning it:

• Rotates cutting tools (milling, drilling, boring)
• Handles heavy machining loads
• Is used in machines requiring:
  • high cutting torque
  • stable low-speed performance
  • strong continuous power output

Typical applications:

• machining centers
• heavy-duty milling machines
• industrial CNC production lines

🧠 Code breakdown

• SJ-D → spindle motor series
• 11 → rated power (11 kW)
• /100 → standard frame size variant
• -01 → design revision / configuration version

📐 Typical characteristics

• Largest power class in SJ-D /100 frame family
• High torque output for demanding cutting operations
• Designed for continuous industrial operation (S1 duty)
• Precision-balanced rotor for stability at medium/high speeds
• Integrated into spindle systems via belt or direct coupling depending on machine design

⚠️ Important notes

• Not a servo motor (does not control axis positioning)
• Not a linear or torque motor
• Requires Mitsubishi spindle drive (MDS series or equivalent)
• Proper cooling and bearing lubrication are critical due to high load

🧠 Simple explanation

SJ-D11/100-01 is a 11 kW CNC spindle motor used to rotate heavy cutting tools with high torque and stable power in industrial machining centers.
