Abstract:
1. A handle control provided with an angular position sensor; the handle control comprises: a supporting body, which is provided with a central through hole and is adapted to be fitted about a handlebar to be rigidly fixed to the handlebar; a twist grip, which has a tubular shape, is rotationally carried by the supporting body and is centrally perforated to be fitted about the handlebar so as to rotate with respect to the handlebar; and an angular position sensor adapted to read the angular position of the twist grip and comprising at least one rotor, which is supported by the twist grip to rotate along with the twist grip, and at least one reader, which is carried in a stationary position by the supporting body, is arranged close to the rotor, and is suitable for a contactless and remote reading of the orientation of the rotor; the handle control is characterized in that the rotor of the angular position sensor is magnetless, is adapted to influence an electric field, and comprises at least one closed turn made of an electrically conductive material and having a number of lobes distributed about a rotation axis of the twist grip; and the reader of the angular position sensor generates an electric field, which is reflected by the turn of the rotor and then the reader reads the electric field reflected by the turn.
