Akwai ana amfani da control synchros don maimaita cutar a cikin sassan kontrollo yawan kayan adadin shafi. Abubuwan system sun hada da biyu na biyu daga cikin abubuwan:

• Synchro Transmitter

• Synchro Receiver

Synchro yana iya amfani da biyu na biyu daga cikin abubuwan. A nan za a bayyana cikakken transmitter da receiver.

Synchros Transmitter

Tasirinta shi taɗa da aikinsu a tare da three-phase alternator. Stator na synchro an yi da steel don kudeta cutar iron. Stator an yi da slots don aikin three-phase windings. An sa shi 120º daga baya zuwa babban birni.

indace (Vr) ita ce root-mean-square (r.m.s.) value of the rotor voltage, and ωc) ita ce carrier frequency. Coils na stator windings an kofara a tare da star configuration. Rotor na synchro taɗa da dumbbell-like shape, da concentric coil an yi aikanta. Alternating current (AC) voltage an yi lafiyar da ita a kan rotor through slip rings. Tasirinta synchro ta shahara a cikin figure na biyu.Idan ake yi lafiyar da ita a kan rotor na transmitter kamar yadda ake nuna a figure na biyu.

Idan ake yi lafiyar da ita a kan rotor, yana ba da magnetizing current, wanda yana gina alternating flux along the rotor's axis. Saboda mutual induction between the rotor and stator fluxes, yana yi lafiyar da ita a kan stator windings. Flux linkage a kan stator winding proportional to the cosine of the angle between the axes of the rotor and the stator. Saboda haka, yana yi lafiyar da ita a kan stator winding. Idan V1, V2, and V3 ne voltages induced in the stator windings S1, S2, and S3 respectively. Figure na biyu ta shahara position na rotor na synchro transmitter. A nan, axis na rotor ya kafa angle θr with respect to the stator winding S2.

Biyu na biyu daga cikin terminals na stator windings

Variation na stator terminal axis concerning the rotor ta shahara a cikin figure na biyu.

Idan angle na rotor zero, maximum current yana gina a kan stator winding S2. Zero-position na rotor ta shahara as reference for determining the angular position of the rotor.

Output na transmitter an yi lafiyar da ita a kan stator winding na control transformer, kamar yadda ake nuna a figure na biyu.

Currents of the same magnitude flow through the transmitter and the control transformer of the synchro system. Saboda circulating current, yana gina flux within the air-gap na control transformer.

Flux axes na control transformer and the transmitter ta shahara alignment. Voltage induced in the rotor na control transformer proportional to the cosine of the angle between the rotors of the transmitter and the control transformer. Mathematically, voltage is expressed as

Indace φ represents the angular displacement between the rotor axes of the transmitter and the controller. Idan θ-90, axes na rotors na transmitter and the control transformer perpendicular to each other. Figure na biyu ta shahara zero-position na rotors na transmitter and the receiver.

Idan rotors na transmitter and the control transformer rotate in the same direction. Idan rotor na transmitter deflected by an angle θR, and deflection angle na control transformer's rotor be θC. Then, total angular separation between the two rotors is (90º – θR + θC)

Voltage at the rotor terminals of the synchro transformer is given as

Small angular displacement between their rotor position is given as Sin (θR – θC) = (θR – θC)

On substituting the value of angular displacement in equation (1) we get

Synchro transmitter and the control transformer together used for detecting the error. Voltage equation shown above is equal to the shaft position of the rotors of control transformer and transmitter.

Error signal an yi lafiyar da ita a differential amplifier which gives input to the servo motor. Gear na servo motor rotates the rotor of the control transformer

Figure na biyu ta shahara output na synchro error detector which is a modulated signal. Modulating wave above shown the misalignment between the rotor position and the carrier wave.
