Working Principle
The brushless resolver consists of two parts, one of which is a resolver. The resolver has a stator and a rotor, and the stator and rotor are respectively wound with two-phase AC distributed windings, and the shafts are perpendicular to each other; The other part is the transformer, its primary coil is wound on the transformer rotor coaxial with the resolver rotor shaft, and rotates with the rotor shaft, the primary coil is connected in parallel with one winding of the resolver rotor, and the other winding of the resolver rotor is connected with high impedance, the secondary coil of the transformer is wound on the stator spool concentric with the rotor, and the wire end of the secondary coil leads to the output signal.
Durability and Heat Resistance
Made from high-strength materials, resolvers can operate normally in high-temperature environments, exhibiting high heat resistance.
Impact Resistance
Due to their compact structure, resolvers are effective at preventing external impacts, demonstrating high impact resistance.
Interference Resistance
During signal transmission, resolvers have some resistance to electromagnetic interference, ensuring the quality of signal transmission.
Low Cost
Compared to other high-voltage transformers, resolvers have a simpler structure and lower production costs.
Application
Resolvers are widely used in various fields, including power systems, industrial production, transportation, and communication systems.
