Industrial Application

Synchro/Resolver Systems for Rail & Locomotive Applications

AS9100D ITAR Nadcap

Overview

Rail and locomotive systems rely on synchro and resolver position feedback for traction motor control, switch position indication, turntable positioning, and brake system monitoring. These applications demand extreme environmental ruggedness — constant vibration, wide temperature ranges, electrical noise from traction motors, and exposure to diesel exhaust, water, and debris.

CCC's ruggedized resolvers and synchro converters have been proven in rail applications worldwide, providing the reliable absolute position feedback that rail safety systems demand.

The Challenge

Rail vehicles generate extreme electrical noise from high-power traction systems that interfere with sensitive position sensors. Constant vibration, shock loads, and temperature cycling destroy conventional sensors. Position feedback systems must be fail-safe and provide absolute position data without initialization sequences.

CCC's Solution

CCC's brushless resolvers are inherently immune to electrical noise — they are passive electromagnetic devices with no electronics at the sensing point. Full transformer isolation in our converter modules provides additional protection against common-mode noise. Our products operate across the full military temperature range and survive shock and vibration levels that exceed rail requirements.
