Precision Automation Actuator Features Closed-Loop Force and Position Control

Precision motion control systems leader PI recently released a new series of actuators based on PIMag non-contacting voice-coil linear motor technology to ensure greater dynamics and positioning accuracy. With low wear and high lifetime, different travels and force capabilities are available, in addition to custom engineered solutions.

Force and Position Control with one Controller

The V-273 automation actuator comes with a unique controller that reads the actuators force and position sensors in parallel and seamlessly switches from closed-loop force control to position control, and vice versa. OEM and industrial applications with rigorous throughput and uptime requirements benefit greatly from these features. With force resolutions to the Milli-Newton range, and 100 nanometer linear encoder resolution, the mechanism provides ultra-smooth action transitions.

More than 10 Million Cycles Life Time

Step size and frequency are variable and allow the user to control the desired speed and positioning resolution. The position sensor resolution of the new N-472 actuator is below one nanometer. PiezoMike products simplify the automated adjustment of mechanical and opto-mechanical components. Motion ranges from 7.5mm to 26mm are standard, as well as vacuum capability.

Applications Examples

Fields of application where PI linear actuators are successful include automation applications, OEM automation drives, and micromanipulation.

Features & Advantages

  • High Speed to 250mm/sec
  • High precision with 0.1µm linear encoder
  • Force sensor option, high sensitivity 5mN
  • 20mm Travel
  • 8N Pushing Force
  • Design Resolution 0.002µm
  • More than 10 million cycles lifetime
  • C-413 Motion controller for simultaneous position and force control

Custom Designs for Industrial Customers

PI has a long history of working with OEM manufacturers and can easily modify existing designs or completely customize devices to fit the exact requirements of the application.
