Motorized Ball Screw Actuator: Linear Precision for Space-Saving Medical Devices


This Tech Talk examines the benefits of motorized ball screw actuators and how they can provide linear precision for medical devices. It also explains how a precision ground ball screw is integrated directly into a NEMA 17 stepper motor to achieve a space-saving design.

Topics include:

  • How a fully integrated assembly results in a compact design solution with streamlined design and assembly requirements
  • How a precision ground ball screw offers higher efficiency, lower friction, smoother operation, improved rigidity, and longer life than lead screws
  • How a higher ball screw efficiency produces a smaller motor package and decreases energy usage
