Mitsubishi M80 Linear Servo Motor 200V LM-FP4B-12M-1WWO

LM-FP4B-12M-1WW0 (often typed as “1WWO”) is a Mitsubishi Electric LM-F series linear servo motor primary side (coil assembly). It is a 1200 N liquid-cooled thrust class linear motor designed for high-speed CNC and industrial automation systems.

🔧 Key specifications (LM-FP4B-12M-1WW0)

These values are listed in Mitsubishi’s official LM-F series specification tables.

📐 Mechanical details

Official Mitsubishi outline drawings specify:

• Motor width: 200 mm
• Motor length: 290 mm
• Mounting: 3×3-M8 screws
• Integrated thermistor connector
• Cabtyre power and thermistor cables
• Cooling port: Rc1/4

⚙️ What it is used for

This linear motor is commonly used in:

• CNC linear axes
• Semiconductor equipment
• Precision automation systems
• High-speed positioning stages
• Pick-and-place systems
• Direct-drive machine axes

Unlike rotary servo systems, it produces direct linear motion without:

• ball screws
• belts
• gearboxes

This provides:

• zero backlash
• high acceleration
• smoother positioning
• lower maintenance

⚠️ Important technical notes

• Requires matching LM-FS40 magnet track secondary side.
• Strong magnetic attraction force (9000 N) requires careful installation.
• IP00 means the motor must be installed inside a machine enclosure.
• Liquid cooling doubles continuous thrust capability from 600 N to 1200 N.
• Mitsubishi provides official DXF CAD files for this exact model.

🧠 Simple explanation

LM-FP4B-12M-1WW0 is the moving coil section of a Mitsubishi linear servo motor system capable of generating up to 3600 N peak thrust for high-speed, precision straight-line motion.
