Report from Hannover: New SEW system designer packages, stainless steel gear motor
New SEW Eurodrive Variolution packages are aimed at system designers; KESA37 gear motor is targeted at food & beverage and pharmaceutical industries. See image, closeup. Link to other coverage from Hannover Fair 2009.
The Variolution package, developed with system designers in mind, includes SEW drive technology as well as related components such as sensors and cables. Integrated software modules in the Variolution package control the sequence of motion via decentralized intelligence, thereby reducing the workload on the higher-level control unit, as well as the need for programming.
The software module also features automatic load recognition, enabling it to adjust the sequences of motion to suit the load situation. This allows for the use of application-specific motion sequences as well as energy-efficient operation and faster cycle times.
The features of the individual packages—15 are currently offered, primarily focused on logistics, material handling, and the automotive industries—are not limited to a basic solution and can be customized based on application.
Because the modules are integrated on the device, shorter reaction times are possible, and allow the modules to operate independently of a central PLC.
Stainless steel gear motors
SEW KESA37 stainless steel gear motors provide motion where machines and systems must be cleaned intensively. Because of its special housing design and the use of high-quality stainless steel, the gear motor is designed for use in the food and beverage and pharmaceutical industries, as well as in constantly wet environments. The gear motor is built entirely using stainless steel to prevent corrosion.
SEW claims the KESA37 has easy-to-clean surfaces that offer resistance to acid and alkaline solutions. Recesses that can collect dirt and liquid are said to have been largely eliminated. All seals and connections are IP69K rated.
