What is a resolver?
Resolver is the current domestic professional name, referred to as "rotating change". Because the basic principle of its work is the Transformer, the air gap of the "transformer" on the stator changes periodically during the work process by rotating the rotor, and then forms the function of monitoring the angular displacement (speed and position) of the motor rotor, so its full name is rotating transformer, which can also be translated into Rototary Transformer. However, this name is rarely used in English, and the general English name is Resolver.
The Applications and Future Trends of Sensor Resolvers
Electric Motors and Servo Systems: Sensor Resolvers are widely employed in electric motors and servo systems to provide accurate feedback on the rotor's angular position. This feedback is essential for closed-loop control systems, enabling precise positioning and velocity control.
