Linear motors are faster and more
compact
Short and ultra-compact linear motors offer speeds of up to twice that of earlier models that are suitable for short, rapid- stroking mechanisms.
With the introduction of its new short and ultra-compact 'S' Series, GE Fanuc Automation can now supply three lines of linear motors, fitting many different requirements They are all made at the recently-commissioned high-tech FANUC plant near Tokyo that is dedicated exclusively to linear motor production

GE Fanuc supervisory control software is advanced
GE Fanuc Intelligent Platforms has launched its Proficy HMI/SCADA iFIX 5.0 which features 'next-generation' visualisation and real-time information management.

Both the new S series motors and an updated high-voltage (HV) version of the line from which they have been developed offer speeds of up to twice that of earlier models.
High speed - developed in recognition of the special need for linear motors that are suitable for short, rapid- stroking mechanisms, the 'S' (short) series of linear motors parallel the existing and well-established line up.
With their wide and short coils, the S-series models make an excellent choice for compact, high productivity machines such as small automatic lathes, machining centres, grinders, presses and broaching machines.

Maintenance Gateway software closes the loop between production and maintenance systems to improve asset reliability, reduce failure rates and increase production uptime.
Management software drives factory performance
GE Fanuc Intelligent Platforms said that the latest version of its Proficy Plant Applications v4.4 production management software improves factories' ability to drive performance.
They are compatible with either 200 or 400 V power input with the latter version being capable of speeds of up to 4m/second.
Output of this range extends from 3.3kN up to 17kN.
Compactness - another feature of the new S-series is that, because the motors themselves are shorter, albeit wider, the overall axis length required on short-stroke machines can be reduced by as much as one third.
This is of considerable significance in reducing overall machine size in applications where several axes are involved.
For these reasons, forward thinking machine tool designers are taking a much increased interest in the benefits that the use of linear motor technology brings.
Wide choice - the benefits of HV drives have also now been extended to customers intending to specify the existing 'long and thin' range of GE Fanuc linear motors mentioned previously.
The HV option applies to the full series of long and narrow linear drives.
Using the new 400V amplifiers, with outputs carefully spaced in frequent steps from 3kN to 15kN, machine designers are able to closely match the most suitable model to suit any desired application for maximum operational efficiency.
Considered by some to represent the ultimate combination of high-speed and high-precision in modern servo motor design, the new 400 Volt HV series of GE Fanuc linear motors offer acceleration rates of up to 40G.
They feature special high-speed windings that decrease impedance to give extra-fast response rates when used as servos and are already finding application in the latest generation of machine tools and other specialised machinery.
Small linear motors - in addition to the two product lines detailed above, there exists also a range of small linear motors from 300N up to 1500N.
These are primarily intended for use on small, compact machines and, used in conjunction with GE Fanuc digital amplifiers, they exhibit outstanding acceleration (27G) and great stability at high speeds. Request a free brochure from GE Fanuc Intelligent Platforms UK ...
