(electricity) An electric system for transmitting angular position or motion in the simplest form it consists of a synchro transmitter connected by wires to a synchro receiver more complex systems include synchro control transformers and synchro differential transmitters and receivers. In this thesis, the individual components of the brushless dc synchro drive system are described. Each channel is implemented using DDC converters. But just got an email that they are recommending a resolver due to the high speeds (10,000 RPM) Is a resolver sufficent for syncing for rigid tapping Im not very familiar with the resolvers so any input is appreciated.
Synchros are often used for measuring the angle of a rotating machine such as an antenna platform. The synchro drive system can, for example, replace a steering column where the master is connected to the steering wheel and the slave would control the direction of the front wheels. The Synchro/Resolver series of products provide fully independent Synchro/Resolver-to-Digital and fully independent Digital-to-Synchro/Resolver channels which are available on 6U VME64x module. I originally requested the motor with absolute encoder for rigid taping syncing and orientation. So the shaft angle can be determined by detecting the output voltage.Ĭonsequently, what is a synchro used for?Ī synchro (also known as selsyn and by other brand names) is, in effect, a transformer whose primary-to-secondary coupling may be varied by physically changing the relative orientation of the two windings. Uses Navigation and fire control for ships, antenna control, aircraft applicationss such as radar, gimbals, fuel valves, landing gear, reverse thruster, cabin pressure. Measurement Used for 360° rotational position.
When a shaft of a control transmitter (CX) or of a brushless control transmitter (BCX) is rotated, 3-phase output voltage changes corresponding to the shaft angle. Synchro / Resolver Characteristics Internals Similar to a standard transformer with windings and laminations. The transmitter and the control transformer are the two main parts of the synchro.Īlso Know, how does a synchro transmitter work? Control Synchro detects a rotation angle by reading output voltage.

It is used as an error detector and as a rotary position sensor. Definition: The Synchro is a type of transducer which transforms the angular position of the shaft into an electric signal.
