Mitsubishi M80 Linear Servo Motor 200V LM-FS40-1WW0

LM-FS40-□-1WW0 is the Mitsubishi Electric LM-F series secondary side (magnet track / magnetic rail) used with LM-FP4 series linear motors.

It is the wide-frame (40 series, 200 mm class width) permanent magnet rail that the moving coil (LM-FP4A/B/D/F/H) runs over.

From Mitsubishi specifications:

⚙️ What it is

LM-FS40-□-1WW0 is:

• the stationary magnetic rail (secondary side)
• used with LM-FP4 series linear motors:
  • FP4B (12M)
  • FP4D (24M)
  • FP4F (36M)
  • FP4H (48M)

Together they form a direct-drive linear motor system (no ball screw, no belt).

📐 Mechanical characteristics

• Width: 200 mm class
• Mounting: M8 through holes
• Magnet pitch: 96 mm standard structure
• Pole alignment reference markings included
• Protection: IP00 (must be inside machine enclosure)
• Material: permanent magnets embedded in epoxy housing

⚠️ Important notes

• Extremely strong magnetic attraction (up to 36,000 N system class depending on motor pairing)
• Must be installed with precise alignment to avoid:
  • drag force loss
  • heating
  • coil damage
• Not a standalone part — always paired with LM-FP4 coil unit
• Requires clean, rigid, non-magnetic mounting surface

🧠 Simple explanation

LM-FS40-□-1WW0 is basically the magnetic “rail track” of a Mitsubishi linear motor.

The LM-FP4 coil is the moving part, and this LM-FS40 rail is the fixed magnetic field it travels over.
