Resolvers are popular analog angle transducers. Due to the perpendicular arrangement of the two coils, it is possible to read the angle on the basis of the given power supply. They are much more resistant to mechanical failure, but less accurate than encoders. They are commonly found in synchronous motors from manufacturers such as Kuka, Siemens, Kollmorgen or B&R. The most popular manufacturers of resolvers are LTN, Tamagawa, Kollmorgen or HAROWE.
