All-electric tube bending machine builder Unison produces its machinery for sectors ranging from aerospace and marine, to automotive and manufacturing. The company, however, wanted to build greater numbers of machines, so turned to Moog Industrial Group for the brushless servo motors and planetary roller screws for these.

Unison now produces a range of machines for tubing diameters from four to 220m, and also supplies custom designs and builds complete production cells for high-volume, high-speed manufacturing. Servo motors and planetary roller screws are vital elements in its machine architecture and, as such, they must meet stringent requirements. To suit such demands, Moog’s servo drives and brushless servo motors offer the highest dynamics, power density and reliability, it claims. Today, the company offers three types of brushless motors: Maximum Dynamic (MD), Compact Dynamic (CD) and Explosion Proof; all of which are available in a variety of standard and customised options. Its planetary roller screws, meanwhile, cover a wide range of static and dynamic loads, with high accelerations to enable fast duty cycles. Customised designs are also available.

Alan Pickering, managing director at Unison, said: “The team at Moog worked with us to reduce lead times, enabling us to build more machines per year and, going forwards, is prepared to help us to further improve our machine efficiency. We are now more competitive in the market and use products that require less energy, while future proofing our machines.”
