The pulsating magnetic field generated here is induced via the rotating rotor winding into the two secondary windings which are offset by 90°. These induced voltages have the same frequency and phase position as the excitation signal at the primary winding. However, the amplitude level depends on the position of the secondary windings relative to the rotor winding. If the rotor winding is parallel to a secondary winding, the induced voltage is at a maximum. A sinusoidal oscillation and a cosinusoidal oscillation are generated by the secondary windings offset by 90°, the evaluation of which enables the position to be determined unambiguously.
What is a resolver and what is it used for?
A resolver is a component or service that is used to determine the IP address of a specific domain. It is used to perform name resolution, i.e. it translates the domain name into the corresponding IP address.
A resolver is normally used by a client (e.g. a web browser) to determine the IP address of a domain so that it can establish a connection to the corresponding server. The resolver sends a request to a DNS (Domain Name System) server and receives the IP address of the requested domain in response.
The resolver is an important part of the DNS system and plays a crucial role in communication on the Internet, as it helps to ensure that domain names can be converted into the corresponding IP addresses.

How does a resolver work and what advantages does it offer over other position sensors?
A resolver is an electrical sensor that is used to measure the position, speed and direction of rotating objects. It consists of a fixed stator and a rotating rotor. The stator contains coils that are wound in a sinusoidal pattern, while the rotor has a two-pole structure.
The resolver works by feeding an alternating current signal into the coils of the stator. The signal induces a voltage in the rotor that depends on the position of the rotor. The position of the rotor can be determined by measuring the phase shift between the incoming signal and the signal coming from the rotor.
A resolver offers several advantages over other position sensors, for example:
1. High resolution: Resolvers can offer very high resolutions, which means that they are able to perform very accurate position measurements.
2. Robustness: Resolvers are very robust due to their mechanical design and can withstand high temperatures, vibrations and other environmental conditions.
3. Absolute position measurement: In contrast to incremental encoders, a resolver provides an absolute position measurement. This means that the resolver knows the exact position of the rotor at all times without the need for referencing or initialization.
4. High speed: Resolvers are capable of detecting very high speeds, making them ideal for applications where fast movements need to be detected.
5. Low electronic interference: Because resolvers use analog signals, they are less susceptible to electronic interference and provide reliable and accurate position measurement.
Overall, a resolver offers a precise, robust and reliable solution for the position measurement of rotating objects in various applications such as motors, robots, machines and other industrial applications.

How accurate is the measurement with a resolver and how high is the resolution?
A resolver is an electrical measuring device that is used to measure the position, speed or direction of a rotating object. It consists of a fixed stator and a movable rotor, both of which are equipped with a winding system.
The measurement with a resolver is carried out by applying an AC voltage to the stator windings and measuring the induced voltages in the rotor windings. The position of the rotor can then be determined using the phase shift between the applied voltages.
The resolution of a measurement with a resolver depends on various factors, such as the number of poles in the resolver, the frequency of the applied AC voltage and the quality of the evaluation electronics used. As a rule, the resolution of a resolver is in the range of a few angular seconds to a few angular minutes.
