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

Spindle Motors

Spindle motors αil series

 

Powerful motors for high acceleration with high mechanical precision and low vibration (V3) – suited to spindles of high performance and large size machines.

  • wide range of constant power up to high speed by winding switching
  • power range 0.55-150 kW
  • large torque at low speed available
  • special versions with hollow shaft for centre-through-coolant or liquid
  • cooled motors available
  • protection class IP40, with oil seal IP54, IP65 as option for some models

Spindle motors βil series

Compact motors providing high power/torque and an excellent price/performance ratio.

  • high efficiency and low heat generation
  • output power 3.7-15 kW
  • suitable for small and medium size machines such as compact lathes
  • protection class IP40, with oil seal IP54

Asynchronous built-in spindle Motors

Asynchronous built-in spindle motors BiI series

Compact built-in motors for compact, high speed, and high performance machines with best adaption in mechanical machine design.

  • large torque at low speed – high power at high speed
  • power range 0.75-50kW
  • larger torque and higher power achieved by efficient heat radiation of stator
  • resin mold (option) or copper-bar rotor (some models)
  • maximum speed up to 70000 rpm

Synchronous built-in spindle Motors

Synchronous built-in spindle motors BiS series

Compact built-in motors with high torque for tough material (e.g. Titanium) and heavy cutting processes.

  • large torque at low speed – strong neodymium magnet rotor structure
  • power ratio 11-80 kW
  • low ripple – optimum magnetic circuit design
  • larger torque and high power achieved by efficient heat radiation of stator resin mould
  • suitable for lathe and gear cutting machines
  • maximum speed – 33000 rpm
