Because in motion control, as in life, the angle is everything. And nobody ever explained the angle better than Moog. This feature is a tribute to the technical writers, applications engineers, and analog designers at Moog Inc. who created and maintained the Synchro and Resolver Engineering Handbook—a work that continues to turn up on desks from Cape Canaveral to Shenzhen.
For over half a century, this handbook has been more than a product catalog. It is a Rosetta Stone for translating the physical world of rotating machinery into the precise, unforgiving language of electronic feedback. Before optical encoders became cheap and ubiquitous, before Hall-effect sensors saturated the market, the synchro and the resolver were the undisputed kings of angular measurement. And Moog Inc.—a company more famous for its hydraulics on fighter jets and amusement park rides—wrote the definitive text on how to wield them. Synchro And Resolver Engineering Handbook Moog Inc
Many companies stopped printing their handbooks. But Moog, stubbornly analog, kept the Synchro and Resolver Engineering Handbook in print—or at least available as a PDF. Why? Because the real world is analog. Because in motion control, as in life, the
The handbook, in its quiet way, predicted this. Its chapters on “Environmental Performance” and “Reliability Under Vibration” were not theoretical. They were the product of Moog’s own test labs—shaker tables, thermal chambers, and life-cycle test rigs running for years. Today, you can download the Moog handbook (now often integrated into their broader “Motion Control” technical documentation). A fresh engineering graduate might look at it and ask: Why learn this? My servo drive auto-tunes. My FPGA handles the R/D conversion in a few microseconds. who created and maintained the Synchro and Resolver
