INDUCTIVELY COUPLED DRIVE MODULE FOR ELECTRICALLY POWERED MODELS

摘要

An inductively coupled drive module for small scale model vehicles, the module including an electric motor having at least one output shaft having an axis of rotation; and at least one inductive coupling, the inductive coupling having: a body which includes a drive shaft which is coaxial with said output shaft, an opening to permit a first end portion of said output shaft to extend within the body, bearings located within the body to permit the body to rotate about said axis but independently of rotation of said output shaft, and a member mounted on said output shaft for rotation therewith and within a cavity formed in the body, the member being: (a) made from or includes magnetic material, or (b) made from or includes electrically conductive material; and wherein the body is: (c) made from or includes electrically conductive material, (when the member is made from or includes magnetic material), or (d) made from or includes magnetic material (when the member is made from or includes electrically conductive material), the arrangement being such that when the electric motor rotates and its output shaft rotates, the member rotates within the body so that induced currents will flow in the body or member which currents will react the magnetic material in the member or mounting body and cause a torque to be applied to the body to thereby cause rotation thereof and consequential rotation of the drive shaft.
