Precise voice coil linear actuator in a compact package

28 August 2014

Incorporating a linear encoder and optional force sensor, the new V-273 voice coil linear actuator from PI offers speed and precision in a compact package.

Built for industrial applications the V-273 actuator integrates a voice coil magnetic drive with linear guiding and an optical linear encoder.  The servo update rate allows the drive to operate at a velocity of up to 200mm/s in closed loop while maintaining a resolution of 0.1µm.

The actuator has a force handling of 6N and can be supplied with a force sensor with 5mN resolution.  The C-413 motion controller is designed to work with the drive and can provide simultaneous position and force control.

Suitable for automation and micro manipulation tasks, the actuator can be easily integrated into a mechanical system by coupling the load to be guided to the moving runner.

PI offers this new technology to complement existing drives based on piezo, stepper and dc motors.

PI's UK based operation can provide support for, and advice on the choice of drive technology for a specific application.
