Synchro/Resolver Simulators and Controllers

Hardware in the Loop

Engine Test

They can be used to create virtual environments to test and verify integrated aerospace components and software. Decrease development time with the ability to design in parallel.

UEI hardware is built to withstand harsh environments. It is rated to 100G shock and 5G of vibrations. It has been trusted by many companies in their engine testing needs.

Simulator

Embedded Controller

Whether flight tests or simulators, the simulated output stimulus may be used as a software-controlled input stimulus. In addition, UEI reduces wiring needed by utilizing ethernet for communications.

Monitor your synchro/resolver application with our programmable automated control (UEIPAC). This allows you to remotely monitor your system without having to have a host system.

Synchro Resolver to Digital Converter Boards

Synchro Resolver Angle Indicator

UEI’s DNx-AI-255/256 are ideal Synchro/Resolver to Digital Converter Board solutions. We take the input from a synchro/resolver, process it so our system can recognize what position the synchro/resolver is in, then you can store this data or use it within your application.

UEI provides the tools to simulate, monitor, and control angle indicator applications. Changes move the rotor to a different angle, and the output of the synchro/resolver will change. Even if the system power is turned off and back on again, the synchro/resolver will still output the right angle.

Synchro/Resolver FAQ

What’s the difference between synchro and resolver?

Synchro: Transducer that uses a transformer whose primary-to-secondary coupling may be altered by changing the relative orientation of the two windings. Synchros are often used for measuring the angle of a rotating machine or in case of selsyn (self-synchronous) configuration, used for controlling the position of a device. In its general physical construction, it is much like an electric motor. The primary winding of the transformer, fixed to the rotor, is excited by an alternating current causes voltages to appear between the Y-connected secondary windings fixed spatially at 120 degrees to each other on the stator. The voltages are measured and used to determine the angle of the rotor relative to the stator.

Resolver: Type of rotary electrical transformer used for measuring degrees of rotation. The name resolver comes from resolving an angular input in to its x and y components. It is considered an analog device and has digital counterparts such as the digital resolver, rotary (pulse) encoder.
