Improving on traditional resolvers

Improving on traditional resolvers The new SEK52 capacitive encoder from SICK UK is set to have a profound impact within all industries and applications that employ brushless servo technology. 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. As the new encoder is also mechanically compatible with most applications, SICK envisages a significant market shift away from resolvers to this new higher-accuracy technology. Coupled to brushless servo motors, SICK reckons the market potential of this new device is massive. Among the many applications suggested by SICK are packaging and print machinery, steel manufacture, textile processing and industrial presses. Anywhere that currently employs servo/resolver combinations can now take advantage of the increased performance offered by this new technology. With its capacitive functional principle, the SEK52 offers a level of robustness comparable to resolvers. But the real differentiating factor behind the SEK52 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.
