Working Principle
The Variable reluctance resolver operates based on the magnetoresistive effect and consist of two main components: a rotating part with a round magnet and a non-rotating part with magnets and coils. The energized signal from the coils generates a magnetic field that induces a magnetoresistive effect on the stationary magnets, allowing the rotating part to sense and output signals.
Differences with Common Resolvers
Signal Transmission: Common resolvers transmit signals through the main and secondary circuits, often using wound wires. In contrast, variable reluctance resolvers rely on the magnetoresistive effect and do not require winding for signal transmission.
Structure: The physical construction and internal components of the two types of resolvers differ, impacting their performance and suitability for specific applications.
Application Scenarios: Common resolvers are typically used in low-voltage applications, such as electrical engineering for small switches or low-power motors. Variable reluctance resolvers are favored for high-precision applications, including precision instruments and control equipment such as the eletric vehicle motor.
Advantages
High precision suitable for critical control systems.
Robust design for applications requiring durability and reliability.
Applicable in scenarios where non-contact sensing is essential.
