Working Principle
The working principle of the brushless resolver is akin to that of a traditional transformer, both operating on the principle of electromagnetic induction. The distinction lies in the fact that the magnetic circuit of the brushless rotary transformer is achieved through rotation.
When alternating current flows through the stator windings, it generates a rotating magnetic field. The magnetic transmission device inside the rotor senses this field and conveys it to the rotor's magnetic body. The magnetic body of the rotor is then energized and outputs mechanical power to the output shaft. As the rotor rotates, the magnetic transmission device simultaneously senses the magnetic fields from both the stator and the rotor, transferring them to the output shaft.
Advantages
Efficiency: With a high energy conversion efficiency, the brushless rotary transformer is more power-saving than traditional transformers.
Reliability: As it does not require mechanical brushes for energy transfer, it is more reliable than traditional brushed rotary devices.
Speed Controllability: The use of a brushless motor drive in the rotating part allows for more precise speed control.
Applications
Brushless resolvers are widely applied in fields such as electric motors, automated control systems, and medical equipment. For instance, they can be used to control fans, pumps, and motion control systems. Additionally, brushless resolvers are employed to enhance the efficiency and reliability of machinery, particularly in processes that involve the operation of large-scale mechanical equipment.
