Abstract: An electromagnetic drive has a uniquely mounted electric coil located within an annular recessed member of the electromagnetic drive to electrically ground the coil to the recessed member along the inner periphery of the coil. A power lead is ultrasonically welded to an insulated outer lead wire of the electric coil so as to have the power lead angularly contact the conductive portion of the lead wire. Energization of the coil by a current passing from the lead wire to the grounded coil produces an electromagnetic field which controls the application of torque between a driving member and a driven member of the electromagnetic drive. The method of mounting the electric coil includes a step wherein the coil is interference pressed onto the annular recessed member in a manner which removes the electrical insulation from the radially inner windings of the coil to electrically ground the coil to the recessed member.
