The Role of Variable Reluctance Resolvers
Variable reluctance resolvers are highly valued for their role in speed feedback systems due to their robust design and high protection level. They feature a separated rotor and stator, ensuring a contactless and brushless operation that can withstand high-intensity vibrations and is impervious to water and oil, extending their operational lifespan to several decades.
Advantages
High Durability: The contactless design contributes to a longer service life with minimal maintenance.
Environmental Resistance: Capable of operating effectively in harsh conditions, including exposure to dust, water, and oil.
Precision: Utilizing specialized conversion chips, variable reluctance resolvers can convert analog signals to digital signals with decoding accuracy comparable to rotary encoders.
Application
In HEVs, variable reluctance resolvers are essential for detecting the rotational speed of the electric motor, which can be installed directly on the motor shaft or through alternative coupling methods. To ensure decoding accuracy, it is necessary to shield the variable reluctance resolver from the motor's internal magnetic field, often requiring the installation of a shielding cover and the use of shielded output lines to reduce electromagnetic interference.
