Abstract
An improved transformer () for use in a power tool () is disclosed, where the power tool () comprises a stationary body () and a shaft () being movable in relation to said body (). The transformer () comprises a stator () being fixed in relation to said body (110) and including one or more stator windings (). The transformer () also comprises a rotor () being movable with said shaft and including one or more rotor windings (). A magnetic field B is shared by said one or more stator and rotor windings (,) and is used for creating a contactless signal connection between said body and at least one sensor of said shaft. According to the present invention, the stator () and the rotor () are arranged for forming a mutual geometrical relationship such that said contactless signal connection is provided for different positions in both an axial direction A and a rotational direction R of said shaft.
