Mitsubishi M80 Normal Specification Motor 200V SJ-D26/80-01

SJ-D26/80-01 is a Mitsubishi Electric SJ-D series AC spindle motor used in CNC machine tools to drive the main spindle (tool rotation).

This is a very high-power spindle motor class (26 kW) in a compact high-torque frame.

🔧 Key specifications (SJ-D26/80-01)

⚙️ What it is used for

This motor drives CNC spindles in:

• heavy-duty machining centers
• large metal removal operations
• high-torque cutting applications
• industrial production machining lines

Typical operations:

• deep rough milling
• large-diameter drilling
• high-load continuous cutting

🧠 Code breakdown

• SJ-D → spindle motor series
• 26 → power class (26 kW capability)
• /80 → compact high-torque frame design
• -01 → mechanical/electrical revision

📐 Typical characteristics

• Very high torque density in compact frame
• Optimized for low-speed heavy cutting
• Strong thermal capacity for continuous industrial duty
• Precision-balanced rotor for vibration stability
• Used in high-rigidity CNC machining centers

⚠️ Important notes

• Not a servo motor (no positioning control)
• Not a linear motor
• Requires Mitsubishi spindle drive system (MDS series or equivalent)
• Cooling and bearing lubrication are critical due to high thermal load
• Machine rigidity is essential due to high cutting forces

🧠 Simple explanation

SJ-D26/80-01 is a 26 kW CNC spindle motor designed for extremely heavy cutting tasks, providing very high torque in a compact industrial spindle frame.
