Parker Trilogy I-FORCE Ironless Motor Positioners cover a wide range

Parker Trilogy’s ironless linear motors offer high forces and rapid accelerations in a compact package. With forces ranging from 5.5lbf (878.6N) continuous up to 5.5lbf ((24.5N) and up to 883lbf (3928N) peak, the I-Force family offers a superior combination of performance and size.

The I-Force (patented RE34674) ‘I-beam’ shape with its overlapping windings allows for a higher power density in a smaller motor, improved heat removal and added structural stiffness. In addition, the ironless (or air core) linear motor design has no attractive force toward the magnets, which provides for easy installation and zero cogging during motion. Ultra high-flex cables come as standard with I-Force motors and on offer are modular magnet tracks for unrestricted travel length.

There are six different product series with configurable options for a ‘best fit’ linear motor solution. The standard travel lengths are up to 3 metres, which can be easily customised. Acceleration is up to 6g’s, speeds to 5 m/s and an internal thermal cutout switch protection and either magnetic coil or optical encoder options with resolutions to 0.1 micron.

 There are single or dual bearing rail positioners to match the performance and cost requirement of users but with precision ground aluminium or steel base for high accuracy as well as maximum life, load and speed. Also included are over travel limits, home sensor and an integral high flex cable. Cable track options accommodate customer payload tubes and cables along with motor and encoder cables. The I-FORCE has multi-axis configurations available and if required there are dual rail positioners, which have bellows as a standard option.

The motors used are of three types, first the ironless motor for ultra high performance and zero cogging. Next the ironcore motor for highest power to package size, and thirdly the slotless motor which has good linear force and smooth translation, at a low cost.

Linear Motor Advantages:

  • High speeds and accelerations
  • Fast response e.g. 100 times that of a mechanical system
  • Stiffness e.g. the spring rate is better than a mechanical system
  • Zero backlash due to direct drive technology
  • Maintenance free, the system is mechanical simple due to the design and much reduced component count
  • Long travels without any performance loss
  • Suitable for vacuum and extreme environments

Miniature positioners available
There are many, many applications for these positioners including semiconductor, electronics, medical, life sciences, machine tools, optics, photonics, printing, scanning, digital fabrication, packaging, material handling, automated assembly, flat panel and solar panel manufacturing.

Incredibly smooth motion, high precision and high force density make the Parker I-Force Linear motors an ideal solution for demanding positioning requirements.
