Concept and Function of Winding
Winding refers to the process of coiling wire around a core to create a conductive path within an electrical device like a transformer. In the context of a resolver, the windings are the most crucial components, responsible for the conversion of energy and the generation of magnetic fields.
Excitation Winding
The excitation winding is the primary winding in a resolver, designed to generate the necessary magnetic flux. It operates by accepting a high-current, low-voltage power supply and converting it into a low-current, high-voltage signal. The simplicity of the excitation winding's structure is a result of its function; it typically consists of only a few turns of wire. This is because the change in magnetic flux it needs to induce is significantly greater than the voltage it must produce, hence fewer turns are required compared to the voltage winding.
Voltage Winding
The voltage winding is the secondary winding in a resolver, primarily used to supply voltage. It contrasts with the excitation winding in that it takes in a low-current, high-voltage signal and outputs a high-current, low-voltage signal. The construction of the voltage winding is more intricate, often featuring hundreds or even thousands of small turns of wire around the core. This complex arrangement is necessary to generate the required voltage differences.
Differences between Winding Types
The distinction between the excitation and voltage windings lies in both their structure and function:
Structure: The excitation winding is simpler, with fewer turns due to its role in generating magnetic flux. The voltage winding, on the other hand, is more complex, with a higher number of turns to produce the necessary voltage differences.
Function: The excitation winding focuses on providing magnetic flux, resulting in a low-current, high-voltage output. Conversely, the voltage winding is tasked with supplying voltage, leading to a high-current, low-voltage output.
