Electrical Resolvers

Electrical Resolvers

Electrical resolvers are electromechanical devices that are used to measure the angular position of a rotating shaft. They are commonly used in industrial and aerospace applications where precise angular measurements are required. Electrical resolvers work by converting the mechanical motion of a rotating shaft into an electrical signal that can be processed by a control system. The basic design of an electrical resolver consists of a stator and a rotor. The stator is a stationary component that contains two sets of windings that are oriented at right angles to each other. The rotor is a rotating component that is attached to the shaft being measured and contains a single winding. As the rotor rotates, the magnetic field produced by the winding interacts with the windings on the stator, inducing a voltage in each winding. The amplitude and phase of the induced voltages are proportional to the angle of rotation of the rotor. Electrical resolvers are known for their high accuracy and reliability, as well as their ability to operate in harsh environments. They are commonly used in applications such as robotics, machine tools, and aerospace systems. However, they are also relatively complex and expensive compared to other types of position sensors.
