No matter what your manufacturing requirement (synchronous or asynchronous), FANUC’s extensive range of spindle and servo and torque motors provide the ideal mix of torque, acceleration, precision and power to perfectly meet your needs.

Servo Motors

Servo motors αi series

These motors offer excellent acceleration and are ideal for use in large high-speed and high-precision machines such as press machines:

  • high feed smoothness
  • two versions available: F – ferrite magnet, S – strong motor (neodymium magnets)
  • wide torque output range 1-3000 Nm
  • maximum speed up to 8000 rpm
  • high resolution αi Series encoder (32000000/rev)
  • protection class IP65 – optional IP67

Servo motors βi series

Offering a high performance-to-cost ratio, these motors are ideal for feed axes on entry level machines, positioning axes and peripheral units:

  • medium inertia – quick acceleration
  • two versions available: F – ferrite magnet, S – strong motor (neodymium magnets)
  • rated torque output 0.2-40 Nm
  • smooth rotation
  • maximum speed up to 6000 rpm
  • high resolution βi Series encoder (1000000/rev)
  • protection class IP65 – optional IP67

Linear Motors

Linear motors LiS series

Direct linear force transmission with easy mechanical structure.

  • high speed (4m/s) and high acceleration (30G) through high rigidity
  • long stroke and high force with multi head configuration
  • large continuous force (WC) 100-7000 N by water cooling
  • max. force 300-17000 N
  • high precision – applying linear scales with high resolution
  • maintenance free mechanism

Torque Motors

Torque motors DiS series built-in servo motors

These are ideal as inbuilt servomotors for tables, turrets and the high precision rotary axes on 5-axis machines:

  • large torque by strong neodymium magnets
  • maximum torque 35-10000 Nm, continuous torque 15-4500 Nm
  • high speed models up to 2000 rpm
  • low ripple – optimum magnetic circuit design
  • maintenance free direct drive
