Abstract

PURPOSE:To contrive improvement in accuracy of coil arrangement and positioing of magnetic field detecting element for the subject motor by a method wherein a magnetic field detecting element, a stator coil and a conductor pattern for wiring are arranged and formed in one body on an insulating sheet. CONSTITUTION:A stator coil sheet 1 is formed by sprially forming conductor patterns 11a-11''a and 11b-11''b on a thin film type insulating sheet 14 by performing plating, etching and the like. Then, on this coil sheet 1, conductor patterns 13-13'' to be used for wiring and magnetic field detecting elemnets 18-18'' are arranged and fixed in one body, and at the same time, conductor pattern to be used for terminal connection of the stator coil and the wiring end conductor pattern for magnetic field detecting element are fixed respectively, and the insulating sheet is taken out from the motor case through the intermediary of the above-mentioned conductor patterns. Thus, as the coil, the magnetic field detecting element and the wiring substrate are formed in one body, the motor can be miniaturized, and the accracy in relative mounting position between the coil pole and the magnetic field detecting element can be improved.
