Copley Motion Systems is launching a new high-performance direct-drive linear motor at the 2009 SPS/IPC/Drives event in Nuremberg. Constructed from austenitic stainless steel, the Servotube Hygienic motor suits applications in demanding industrial environments. Furthermore, the smooth hygienic design is free from dirt traps, so the unit can be used in aseptic environments.
Because there is no mechanical linkage between the fixed forcer body and the moving rod, there is no wear and the integrated field-replaceable polymer bearings require no lubrication. The position sensor is always accurate and is protected from dirt or damage because it is built into the motor's body. This elemental design meets the IP69K ingress protection requirements, allowing the linear motor to be used in dirty or wet environments and to be cleaned with pressurised jet wash systems.
The direct-drive motion is also claimed to offer significant performance improvements compared to existing linear systems. High peak force and low inertia guarantee highly dynamic movements, and the Servotube Hygienic offers 25micron repeatability throughout the lifetime of the linear motor.
Marketing director Steve Hickman comments: "The Servotube Hygienic is the first linear actuator that can be used in the real-life wash-down applications our customers have to operate in. We believe that its IP69K ingress protection rating, non-corrosive all-stainless construction and high-speed actuation offer no-compromise linear motion for the most demanding hygienic and industrial processing environments."
Whereas existing belt-driven and ball screw linear systems comprise several component parts, the Servotube direct-drive linear motors require only a standard servo drive and, where applicable, a linear rail. This reduces system complexity, maintenance and saves space, as no servomotor or gearhead is required.
The Servotube Hygienic operates from a three-phase 600V supply and provides a digital incremental encoder and commutation output for use with most standard digital servo drives.
Available from November 2009, the Servotube Hygienic will be initially available in two models that both offer +/-400micron position accuracy and 25micron repeatability. The XHB3804 and XHB3810 provide 744 and 1860N peak force capability and are capable of speeds of 4.7 and 2.6m/s, respectively. Both models can be water cooled to provide up to 70 per cent extra continuous force for applications requiring high work rates, or for use in environments with high ambient temperatures.
