The SEK/SEL37 capacitative motor feedback systems are at home in two worlds of automation: One the one hand, the present world of resolvers in which users require high performance from absolute position encoders, such as servo motors or feed axes. On the other hand, thanks to the flexibility in connection with the automation engineering features, the SEK/SEL37 devices are particularly interesting for manufacturers of servo motors. With 16 sine/cosine signals per revolution, this family represents the basic solution for MFB systems with the HIPERFACE® interface. The centerpiece of the product family is a bearing-free, capacitive sensor element. The holistic scanning process virtually offsets eccentricity errors and is extremely rugged. Possible sources of error are nearly completely ruled out as there are no wear and tear parts. Furthermore, the motor feedback systems feature high temperature resistance, which was previously reserved for resolvers. SEK/SEL37 motor feedback systems features a HIPERFACE® interface recognized all over the globe, which is supported by many well-known drive manufacturers.
