Introduction Hysteresis and Eddy Current Synchronous Motors Synchronous condenser Reluctance motor Synchronous reluctance Switched reluctance. A synchro is, in effect, a transformer whose primarytosecondary coupling may be varied by physically changing the relative orientation of the two windings. Resolvers are similar to synchros except they have two stator coils at right angles rather than three separated by 120. The most simple resolver, the fourpole, is. We have been a leader in the rotary components industry for over 50 years. Our staff includes electrical, mechanical, manufacturing and software engineers. The guide provides a practical introduction to Digital Signal Processing, covering a wide range of topics. It is an ideal introduction for those new to DSP, and an. Moog Components Group www. One resolver The transolver is essentially a. Synchro Wikipedia. Schematic of a synchro transducer. The complete circle represents the rotor. The solid bars represent the cores of the windings next to them. Power to the rotor is connected by slip rings and brushes, represented by the circles at the ends of the rotor winding. As shown, the rotor induces equal voltages in the 1. Vex does not necessarily need to be connected to the common lead of the stator star windings. Simple two synchro system. A synchro is, in effect, a transformer 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 antenna platform. Synchro Resolver Pdf To Word' title='Synchro Resolver Pdf To Word' />In its general physical construction, it is much like an electric motor. The primary winding of the transformer, fixed to the rotor, is excited by an alternating current, which by electromagnetic induction, causes currents to flow in three Y connected secondary windings fixed at 1. 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 portmanteau of self and synchronizing. Synchro Resolver Pdf CreatorA picture of a synchro transmitter. Synchro systems were first used in the control system of the Panama Canal in the early 1. View onto the connection description of a synchro transmitter. Fire control system designs developed during World War II used synchros extensively, to transmit angular information from guns and sights to an analog fire control computer, and to transmit the desired gun position back to the gun location. Early systems just moved indicator dials, but with the advent of the amplidyne, 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 rotary encoder have replaced synchros in most other applications. Selsyn motors were widely used in motion picture equipment to synchronize movie cameras and sound recording equipment, before the advent of crystal oscillators and microelectronics. Large synchros were used on naval warships, such as destroyers, to operate the steering gear from the wheel on the bridge. Synchro system typeseditThere are two types of synchro systems Torque systems and control systems. 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 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. Control type synchros are used in applications that require large torques or high accuracy such as follow up links and error detectors in servo, automatic control systems such as an autopilot system. In simpler terms, a control synchro system is a system in which the transmitted signal controls a source of power which does the usable work. Quite often, one system will perform both torque and control functions. Individual units are designed for use in either torque or control systems. Some torque units can be used as control units, but control units cannot replace torque units. Synchro functional categorieseditA synchro will fall into one of eight functional categories. They are as follows 4Torque Transmitter TXInput Rotor positioned mechanically or manually by the information to be transmitted. Output Electrical output from stator identifying the rotor position supplied to a torque receiver, torque differential transmitter or a torque differential receiver. Control Transmitter CXInput Same as TX. Output Electrical output same as TX but supplied to a control transformer or control differential transmitter. Torque Differential Transmitter TDXInput TX output applied to stator rotor positioned according to amount data from TX that must be modified. Output Electrical output from rotor representing an angle equal to the algebraic sum or difference of rotor position angle and angular data from TX supplied to torque receivers, another TDX, or a torque differential receiver. Control Differential Transmitter CDXInput Same as TDX but data supplied by CX. Output Same as TDX but supplied to only a control transformer or another CDX. Torque Receiver TRInput Electrical angle position data from TX or TDX supplied to stator. Output Rotor assumes position determined by electrical input supplied. Torque Differential Receiver TDRInput Electrical data supplied from two TXs, two TDXs or from one TX and one TDX one connected to the rotor and one connected to the stator. Output Rotor assumes position equal to the algebraic sum or difference of two angular inputs. Control Transformer CTInput Electrical data from CX or CDX applied to stator. Rotor positioned mechanically or manually. Output Electrical output from rotor proportional to sine of the difference between rotor angular position and electrical input angle. Torque Receiver Transmitter TRXThis synchro was designed as a torque receiver, but may be used as either a transmitter or receiver. Patch Pes 2006 Pc here. Input Depending on the application, same as TX. Output Depending on the application, same as TX or TR. OperationeditOn a practical level, synchros resemble motors, in that there is a rotor, stator, and a shaft. Ordinarily, slip rings and brushes connect the rotor to external power. A synchro transmitters shaft is rotated by the mechanism that sends information, while the synchro receivers shaft rotates a dial, or operates a light mechanical load. Single and three phase units are common in use, and will follow the others rotation when connected properly. One transmitter can turn several receivers if torque is a factor, the transmitter must be physically larger to source the additional current. In a motion picture interlock system, a large motor driven distributor can drive as many as 2. Synchros designed for terrestrial use tend to be driven at 5. Single phase units have five wires two for an exciter winding typically line voltage and three for the outputinput. These three are bussed to the other synchros in the system, and provide the power and information to align the shafts of all the receivers. Synchro transmitters and receivers must be powered by the same branch circuit, so to speak the mains excitation voltage sources must match in voltage and phase. The safest approach is to bus the five or six lines from transmitters and receivers at a common point. Different makes of selsyns, used in interlock systems, have different output voltages. In all cases, three phase systems will handle more power and operate a bit more smoothly. The excitation is often 2. V 3 phase mains power. Many synchros operate on 3. V AC also. Synchro transmitters are as described, but 5. Hz synchro receivers require rotary dampers to keep their shafts from oscillating when not loaded as with dials or lightly loaded in high accuracy applications.
