Synchros The Synchro allows angular position data to be transmitted electrically in remote locations. Synchros are electro-mechanical analog converters which, through electromagnetic means, gives an electrical output that is a function of its rotor position or positions its rotor to an angle that is a function of the electrical input. Synchro housings are similar in construction. The differences are within the internal manufacture to meet the electrical requirement determined by synchro type and customer’s application. Synchro Transmitter A synchro transmitter converts a mechanical input (rotor position) into an electrical output. Input data, in the form of rotor angular displacement “a” degrees, results in a corresponding electrical output at the stator. The stator output voltage is proportional to the angular position of the rotor with respect to the stator. AC voltage input to the single phase Rotor produces output to the three-phase stator. Synchro Differential Transmitter A synchro differential transmitter gives an electrical output which as a function of two inputs, its electrical input and its mechanical input (rotor position). The unit receives angular input data from a transmitter in the form of concise stator voltages. The rotor then modifies and re-transmits this data such that it corresponds to the algebraic sum of the electrical input angle and the relative rotor angle. AC voltage input to the three-phase Stator produces output to the three-phase rotor. Synchro Control Transformer A control transformer, in conjunction with an amplifier and servomotor, converts an electrical input into a rotor position in high torque applications. The electrical output of the control transformer is amplified and applied to a servomotor, which drives the load and the transformer to the null position. This unit receives angular input data from a transmitter in the form of concise stator voltages. The corresponding rotor output voltage is proportional to the sine of the algebraic sum of the electrical input angle and the relative rotor angle. The desired angular output data is the relative angular displacement of the rotor that reduces the output voltage to zero. AC voltage input to the three-phase Stator produces output to the single-phase rotor. Synchros and Resolvers are manufactured in the following forms:
