Abstract

PURPOSE:To make it possible to send electric current that is smooth through the windings of an armature by providing a magnetic angle shaped projection plate on the internal periphery of the central hole of a field magnet and fixing a position detecting element at the position opposite to the magnetic plate. CONSTITUTION:A projecting magnetic plate 24 that is made of steel plate and so on is provided on the inner periphery of a central hole of a field magnet 10 on the side that is opposite to an armature windings 11, and between a magnetic material 24 and a yoke a non-magnetic material 23 is provided. This magnetic plate is formed angle-shaped at each magnetic pole and individual sections of the angle shaped magnetic plate are mutually connected, and holes are pierced through them by means of a press machine, etc. At the inside face of a disc 3 that opposes the magnetic plates 24 and 24' several position detecting elements 25 such as hole elements are distributed and installed on, for instance, the line that is an extension of a conductive body 11a. With this arrangement smooth electric current can be supplied to the armature windings.
