Can somebody please explain me the basics of resolver. How it works? How it calculates angle and velocity? Atleast any proper links. Please help.
A resolver is essentially laminated steel and several coils of copper wire arranged in a particular way. It doesn't do calculations, nor does it lock anything - these things are done by whatever electronics are connected to it.Physicslearner500039 said:Generally how much time does it take for the resolver to lock to the cos and sine signals and calculate the velocity?
A resolver transformer is a type of electrical transformer that converts an input signal into an output signal by utilizing the principle of electromagnetic induction. It is commonly used in applications where precise and accurate angular position, velocity, or motion control is required.
A resolver transformer consists of a primary winding, a secondary winding, and a rotor. When an alternating current is passed through the primary winding, it induces a magnetic field. The rotor, which is connected to the input shaft, rotates within this field, causing the secondary winding to generate an output signal proportional to the angle of rotation.
Compared to other types of transformers, a resolver transformer offers several advantages. It has a high resolution and accuracy, is resistant to electromagnetic interference, and can operate in harsh environments. It also has a long lifespan and requires little maintenance.
Resolver transformers are commonly used in aerospace, military, and industrial applications where precise position or motion control is critical. They are also used in robotics, radar systems, motor control, and servo systems.
When selecting a resolver transformer, it is important to consider factors such as accuracy, temperature range, vibration resistance, and environmental conditions. It is also important to ensure that the transformer is compatible with the input and output signals and can meet the specific requirements of your application.
