Synchro Resolver Pdf
Simple two-synchro system. A synchro (also known as Selsyn and by other brand names) is, in effect, a whose primary-to-secondary coupling may be varied by physically changing the relative orientation of the two windings. Synchros are often used for measuring the angle of a rotating machine such as an platform. In its general physical construction, it is much like an electric motor.
Written by our expert staff, the Synchro/Resolver Conversion Handbook was the first integrated reference source on synchro/resolver data converters, and has served as.
The primary winding of the transformer, fixed to the, is excited by an, which by, causes currents to flow in three Y-connected secondary windings fixed at 120 degrees to each other on the. The relative magnitudes of secondary currents are measured and used to determine the angle of the rotor relative to the stator, or the currents can be used to directly drive a receiver synchro that will rotate in unison with the synchro transmitter. In the latter case, the whole device may be called a selsyn (a of self and synchronizing).
View onto the connection description of a synchro transmitter designs developed during used synchros extensively, to transmit angular information from guns and sights to an, and to transmit the desired gun position back to the gun location. Pes 2012 Ps2. Early systems just moved indicator dials, but with the advent of the, as well as motor-driven high-powered hydraulic servos, the fire control system could directly control the positions of heavy guns. Smaller synchros are still used to remotely drive indicator gauges and as rotary position sensors for aircraft control surfaces, where the reliability of these rugged devices is needed. Digital devices such as the have replaced synchros in most other applications.
Selsyn motors were widely used in equipment to synchronize and equipment, before the advent of and. Large synchros were used on naval warships, such as destroyers, to operate the steering gear from the wheel on the bridge. Synchro system types [ ] There are two types of synchro systems: Torque systems and control systems. Aladdin Hasp Emulator Program on this page. 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. In simpler terms, a torque synchro system is a system in which the transmitted signal does the usable work. In such a system, accuracy on the order of one degree is attainable. In a control system, a synchro will provide a voltage for conversion to torque through an amplifier and a servomotor.
