The application of Resolver in servo systems has become a trend.
In the appliance, whether it is refrigerators, air conditioners, or washing machines, currently all develop to the direction of frequency shift, they all using the sinusoidal control of permanent magnet AC motors. Currently, among the electric vehicles many countries pay great attention, electric vehicles used in the position, speed sensors are all rotary transformer .For example, drive motor and generator location sensing, location of electric power steering motor speed sensor, gas valve angle measurement, measurement of the angular position of the vacuum chamber transmitter, etc., are all used the resolver. In pastic pressure applied to the system, textile system, metallurgy system and other areas, the key components of servo system that servo motor applies is rotary transformer. Resolver’ application in servo systems has become a trend.
