The SYNCHRO CAPACITOR is a unit containing three delta-connected capacitors. It is used in
synchro systems containing either differential transmitters or CTs. The addition of the synchro capacitor
to these systems greatly reduces the stator current and therefore increases the accuracy of the systems.
The SPEED OF DATA TRANSMISSION is simply the number of times a synchro transmitter
rotor must turn to transmit a full range of values. You refer to the speed of data transmission as being 1-
speed, 2-speed, 36-speed, or some other definite numerical ratio.
MULTISPEED SYNCHRO SYSTEMS transmit a wide range of data at different speeds and still
maintain a high degree of accuracy. To indicate the number of different speeds at which data is
transmitted, refer to the system as being a single-speed, dual-speed, or tri-speed synchro system.
A DOUBLE RECEIVER consists of a fine and a coarse receiver enclosed in a common housing. It
has a two-shaft output (one inside the other), and its operation may be likened to the hour and minute
hands of a clock.
