Mitsubishi M80 Spindle Motor 200V SJ-D15/80-01

SJ-D15/80-01 is a Mitsubishi Electric SJ-D series AC spindle motor, used in CNC machine tools to drive the main spindle (tool rotation).

This is one of the highest-power class spindle motors in the SJ-D family you’ve listed.

🔧 Key specifications (SJ-D15/80-01)

⚙️ What it is used for

This motor is used to:

• Rotate CNC machine spindles
• Drive cutting tools under very heavy machining loads
• Support operations like:
  • heavy milling
  • deep cutting
  • high torque drilling

It is typically used in:

• large machining centers
• heavy industrial CNC machines
• production lines with aggressive cutting conditions

🧠 Code breakdown

• SJ-D → spindle motor series
• 15 → rated power (15 kW)
• /80 → compact high-torque frame variant
• -01 → design / construction revision

📐 Typical characteristics

• Very high torque density (large power in compact frame)
• Strong low-speed cutting performance
• Designed for rigid, heavy-duty machine structures
• Precision-balanced rotor for stability under load
• Integrated into CNC spindle via belt or direct-drive coupling depending on machine design

⚠️ Important notes

• Not a servo motor (no axis positioning function)
• Not a linear motor
• Requires dedicated Mitsubishi spindle drive system (MDS series or equivalent)
• Cooling system and bearing condition are critical at this power level

🧠 Simple explanation

SJ-D15/80-01 is a 15 kW CNC spindle motor designed for very heavy cutting, offering high torque in a compact frame for industrial machining centers.
