Parallel Ball Screw Drive Programmable Actuator

PA Actuator™ offers an expanded range of performance by providing higher loads, longer life, and increased duty cycles with higher speeds and programmability.

Nook stepper motors are high-performance drives, based on the latest motion control technology. Advance features include reduced stepper noise, anti-resonance that optimizes torque and nulls mid-range instability. all this offers low-speed ripple smoothing and reduced motor heating.

PA Actuator Advantages

  • Rated for continuous duty.
  • Long service life.
  • Anti-rotation device integrated.
  • Quiet running performance.
  • Complete system from one source including motor, drive, controller, and power supply.
  • Ball screws are used on high-speed applications.

Performance Characteristics

  • High mechanical efficiency.
  • Strokes up to 24 in.
  • Repeatability ± 0.004 in. up to ± 0.001 in.
  • Toothed belt drive (for parallel motor mounting).
  • Standard motor and gearhead flanges for simplified selection. Optional motors are available at customer selection when specified.
  • IP54 (motor dependent)
  • IP65 (motor dependent)
