SERVO MOTOR

TEKNIC SST-1500 DRIVE AND SST- 3450 BRUSHLESS MOTOR SERVOSTEPPERª SYSTEM

CNT Motion Systems utilizes a state-of-the-art ServoStepperª system that outperforms even the best servo systems while utilizing simple "step and direction" control.
  • Low Cost: Same cost as microstepper systems, allowing us to provide our customers with servo quality at a reasonable price.
  • Simple To Use: Same "digital" control as steppers (step and direction).
  • Automatic Electronic Tuning: Optimizes performance for different loads.
  • Stays In Position: Accuracy is constant and load independent.
  • Full Holding Torque: Faster then steppers. Never loses a step!
  • Brushless: No maintenance or dirt.
  • Higher Throughput: Full torque over wide speed range. Ultra-fast settling time. High power density.
  • Excellent Accuracy and Resolution: Regardless of load.
  • Quiet: No motor whine.
  • Smooth Running: Virtually no torque ripple, and no resonance.
  • High Disturbance Rejection: High performance under conditions of unexpected friction, shock, vibration, dirt, sudden load changes, etc.
  • Predictable Performance: Regardless of friction, inertia, speed, external disturbances, etc.
