It is designed to measure these parameters accurately in the presence of highly distorted and noisy signals. 1. In a torque system, a synchro will provide a low-power mechanical output sufficient to position an indicating device, actuate a sensitive switch or move light loads without power amplification. A synchronous-resolver is probably what you refer to as a "synchro" and like you say, it has three windings (on the stator) and also a rotor winding brought out on slip rings. While servos and resolvers are similar to one another in some of their components, they do have some distinct differences that set them apart. Since this geometry changes as the rotor changes its position, then it becomes possible to extract positional information by comparing the output and input . The simplicity of their connection and todays synchro-to-digital and digital-to-synchro converter boards make the synchro a very attractive component. If the SimTraffic simulation associated with Sychro is run for a long enough period, it does appear to illustrate As shown in Figure 1, a synchro has one primary winding and three secondary windings, with each secondary winding mechanically oriented 120 apart.
