‘Resolvers’

An Engineeringtalk guide

Start with the news release SICK motor feedback system has Hiperface interface from Sick Stegmann, which we summarised at the time by saying "SICK Stegmann has introduced its SEK/SEL37 capacitive motor feedback systems.". Several months prior to that, we featured the news release Empire supplies motors for ANSTO applications from Empire Magnetics: "Vacuum- and radiation-hardened gearmotors and resolvers from Empire Magnetics are being utilised by the Australian Nuclear Science and Technology Organisation (ANSTO).".

In January 2009, we covered the news from Inmoco - take a look at Inmoco launches PCB-mounted servo drive which says: "Inmoco has unveiled the ultra-high power density Guitar servo drive from Elmo Motion Control, a PCB-mounted device that delivers up to 5kW of continuous qualitative power, and 70A peak current. ".

Take a look also at the news release from Micronor, Micronor presents fibre-optic rotary encoder, as well as Parker releases intelligent servo drives from Parker Hannifin - Electromechanical and Drives Division, and Lenze launches MCA and MQA servo motors from Lenze.
