Frameless, Brushless Torque Motor


Unhoused arc segmented frameless brushless torque motor has a low inertia moving coil assembly for high angular acceleration applications. It can generate a continuous/peak torque of 480 in.-lb [53 Nm]/1,440 in.-lb [159 Nm].


The rotary three-phase brushless motor, also known as a rotary servo motor, is a direct drive type that is ideal for limited or unlimited, closed loop servo, rotary motion applications. It is capable of very precise position, velocity, and acceleration control when coupled with a rotary encoder for position feedback.



  • Zero cogging 
  • High speed and accelerations of light loads 
  • Low inertia 
  • Multiple motors coils inside a single magnet assembly 
  • Uses standard 3-phase brushless amplifier
