At what frequency do resolvers designed for terrestrial use typically operate?

Resolvers designed for terrestrial use typically operate within the frequency range of 50-60 Hz. This frequency range aligns with standard electrical systems in many countries, particularly those adhering to the electrical grid specifications that utilize these frequencies for power generation and distribution. This makes them suitable for use in applications where synchronization with the mains power is advantageous, such as in industrial and commercial settings.

Operating at this frequency allows resolvers to function effectively in environments where household or industrial power supplies are operating, ensuring that they can accurately reference position or angles in relation to the electrical signal. This provides a stable and reliable performance that is essential for accurate measurements in various applications, such as in robotics, automation systems, and other engineering uses that require precise positioning.

The other frequency options provided do not match the typical operation frequencies for terrestrial resolvers, making the choice of 50-60 Hz the most appropriate and common for these applications.
