Synchro And Resolver Engineering Handbook Moog Inc – No Password
In the world of high-performance motion control, precision is not a luxury; it is a necessity. Whether it is the actuation of a flight control surface on a fighter jet, the positioning of a radar antenna on a naval destroyer, or the robotic arm on a space station, the need for absolute, reliable position feedback is paramount.

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.

Moog’s handbook didn’t just explain what they were; it explained how to weaponize them . It provided the transfer functions, the Scott-T transformer connections to convert three-wire synchro data to two-wire resolver data, and the critical error budgets that separate a functioning radar dish from a gimbal lock in an inertial navigation system.
Because in motion control, as in life, the angle is everything. And nobody ever explained the angle better than Moog. In the world of high-performance motion control, precision
By the late 1990s, the writing was on the wall. Optical encoders with 16-bit resolution were dropping in price. Resolver-to-digital (R/D) converters existed as single-chip solutions from Analog Devices or DDC. The need to understand the analog soul of a resolver seemed to be fading.
As detailed in the Moog documentation, the synchro is primarily a data transmission device. It operates on a three-wire stator system (often referred to as S1, S2, S3). The handbook explains how a synchro transmitter (CX) takes a shaft angle and converts it into a set of three voltages. These voltages can be transmitted over long distances to a synchro receiver (CR) or a control transformer (CT), which then reproduces that angle or provides an error signal.

This article explores the critical content of that handbook, why Moog’s approach to these electromagnetic devices matters, and how this engineering resource remains a gold standard for designers in 2024 and beyond.
Moog did not just sell components; they engineered systems. To ensure that their clients and in-house engineers could flawlessly integrate these electromagnetic sensors, Moog compiled decades of field data, manufacturing tolerances, and theoretical physics into a single volume. Thus, the Synchro and Resolver Engineering Handbook was born. It served as both a product catalog and a graduate-level textbook, bridging the gap between theoretical electromagnetism and practical system design.
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.
