Synchro servo

Synchro system

Its rotor might be synchro-like, or have two sets of windings 90 degrees apart. Synchros can provide this speed and accuracy. What are the disadvantages of using a Synchro? Explain how the two differential synchro systems add and subtract. The principles of Synchro are similar to those of an electrical transformer except that the iron core of Synchro consists of a rotor and a stator. A Synchro transmitter can control more than one Synchro receiver. A synchro transmitter's shaft is rotated by the mechanism that sends information, while the synchro receiver's shaft rotates a dial, or operates a light mechanical load. Two Synchro receivers can receive this input through the interconnecting wiring.

State the purposes and functions of multispeed synchro systems. The safest approach is to bus the five or six lines from transmitters and receivers at a common point.

At the receiver, the magnitude of the 1X channel's error determined whether the "fast" channel was to be used instead. Stale the purposes for zeroing synchros.

synchro error detector

The error signal is amplified by the servo amplifier and applied to the servomotor. The speed is constant and independent of the load. A shaft of the receiver rotates in unison with the rotation of a shaft of the transmitter. Different makes of selsyns, used in interlock systems, have different output voltages.

Synchro receiver

Output: electrical output from rotor proportional to sine of the difference between rotor angular position and electrical input angle. Explain the operation of a control synchro system and how it is used to control a servo system. The holes in those end pieces align with the rotating secondary poles. Name three common synchro zeroing methods and give a brief explanation of each. The term "synchro" is an abbreviation of the word "synchronous. The error signal is amplified by the servo amplifier and applied to the servomotor. In other words, the receiver synchronizes exactly with the transmitter. Figure shows a simple synchro system that can be used to transmit different as of data or information In this system, a single synchro transmitter furnishes information to two synchro receivers located in distant spaces. The airgap flux is uniformly distributed around the rotor due to the cylindrical type of the Synchro Control Transformer. Torque Synchro as above and Control Synchro. Explain what happens when the rotor leads on a synchro transmitter or receiver are reversed.

They have three-lead rotors and stators like the stator described above, and can be transmitters or receivers.
