Outstanding Price/Performance...
Exclusive WorldServo performance features:

 
True, closed-loop, vector torque control with sinewave brushless motor commutation so you can use minimum size motors at the lowest cost, with excellent positioning performance.
  RAS™ (Regressive Auto-Splining™) to double jerk limit the command input for reduced vibration, lower motor requirements and lower cost. It also allows the use of very low cost controllers (documentation for making your own "zero-cost" controller is in this site).
  Automatic adaptive tuning-Inertia Matching Technology™-give you excellent performance even with large inertial loads or varying loads.
  Anti-hunt™ to virtually eliminate servo jitter and hunting even with very high servo gains, and without sacrificing performance.
  and many more (browse this site to learn more)…

Versatile and low cost:
 
  Choose from WorldServo's full line of rare-earth brushless motors or use any standard 3-phase brushless motor, brush-type motor, or voice coil actuator. WorldServo systems are especially well-suited for linear motor applications. You are not limited to one manufacturer's motor line.
 
  You save money because of WorldServo's technological innovations. In moderate quantities (about 8 axes per month), a high-performance WorldServo system including a positioning servo drive, a rare-earth brushless motor (614 watts peak, 141 watts continuous) and a high-resolution encoder is only $640.
