Electronic Monitoring, industrial motors, robots and vehicular power trains are necessary for higher efficiency, reliability, and safety, this technology provides the best angular position in terms of ruggedness, reliability, and resolution. Resolvers are developed mainly for military and aerospace applications. For high angular and velocity rotation of transformer, electronic control systems are necessary, which causes the noisy and rugged environment to avoid these, resolver to digital

... er and op-amps are used. The resolver which is known as a rotary transformer converts the angular position of the shaft into Cartesian coordinates of components. The output of the transducer consists of two signals which are proportional to the sine and cosine of the angle which is represented in the form of a digital counterpart. Resolver to Digital Converter(RDC) driver is placed between microcontroller/ microprocessor and resolver, and to determine the angular position and rotation speed of the motor shaft, sine and cosine signals are used.
