Resolver Technology
What is a High Accuracy Resolver?
A high accuracy resolver is a type of rotary position sensor used to measure angular position with exceptional precision. It operates on the principle of electromagnetic induction, converting mechanical rotation into electrical signals that represent the precise angle of rotation. High accuracy resolvers are characterized by:
Differential Output: They provide differential signals that reflect the angular position of the rotor, allowing for highly accurate feedback.
Robust Construction: Designed for harsh environments, they are highly durable and resistant to extreme temperatures, vibrations, and electromagnetic interference.
High Resolution: Capable of achieving accuracy up to ±0.002% Full Scale (FS), they are ideal for aerospace and defense applications requiring fine control, such as flight control surfaces and engine systems.
Multispeed Options: These resolvers can be designed with multiple poles to increase resolution, providing greater precision in detecting rotational position changes.
High accuracy resolvers are often used in applications where exact angular feedback is critical to system performance, such as in servo-control systems or position monitoring in aircraft and defense systems.
What are Brushless Resolvers and Synchros?
Brushless resolvers and synchros are types of rotary position sensors that, like high accuracy resolvers, provide angular position feedback. However, they differ in design and applications:
Brushless resolvers, as the name suggests, operate without brushes, making them more reliable and less prone to wear in comparison to brush-based systems. They are commonly used in:
DC Brushless Motors: For commutation and control, providing feedback on rotor position to ensure proper timing of electrical signals.
High-Speed Applications: Brushless resolvers are well-suited for environments where high rotational speeds and reliability are essential.
Redundancy and Custom Features: These sensors can incorporate mechanical or electrical redundancy, with multiple channels for added safety. They are also customizable with locking features and gearheads for multi-turn movement.
Synchros are similar to resolvers but are typically used for more complex control and feedback systems. They consist of a transmitter and receiver that work together to transmit angular position information over long distances, making them ideal for applications where real-time data needs to be shared between systems. They feature:
Analog Feedback: Synchros use analog signals to represent the position of the sensor, which can be used for vector control or in servo systems.
Gearheads for Complex Movements: In applications such as nose landing gear steering or flaps/slats control, synchros with gearheads can handle complex multi-turn movements.
Together, brushless resolvers and synchros are widely used in aerospace and defense, offering reliable, brush-free operation and versatile configurations for precise motion control and feedback in systems like cockpit controls, engine systems, and flight controls.
