Motor feedback technology offers increased accuracy
November 1st 2006 The new SEK52 capacitive encoder from SICK is set to have a profound impact within all industries and applications that employ brushless servo technology. SICK says, that not only does it offer 16 times the resolution of a standard resolver, but it does so at a competitive price. Other features, which set the SEK52 apart from traditional resolver technology, include a HIPERFACE interface and an electronic type label. With its capacitive functional principle, the SEK52 offers a level of robustness comparable to resolvers. But its real differentiating factor is its considerably greater accuracy – a direct result of it offering 16 sin/cosine periods compared to just one in a resolver. Its ability to seamlessly integrate into modern automation systems is another major plus. Thanks to its electronic type label it can store information relating to the motor it is paired with, information that can include peak torque, peak current and the motor's speed characteristics. This facility makes set up significantly easier as there is no need to enter motor details manually – leading to quicker and easier drive commissioning. More articles from Erwin Sick Ltd: |
