Abstract
An object of the invention is to provide an armature of an electric motor that provides a maximum of space for winding without causing an increase of the magnetic resistance and reduction of the coil space factor. The armature of the electric motor includes a stator yokeof a stator corewherein a plurality of the stator coresforms a substantially annular shape; and a film insulatorformed corresponding to a toothand a stator yokeof the tooth, shoesandbeing provided at locations corresponding to both side ends of a front portion of a protrusionof the tooth, the film insulatorbeing fittingly fixed to groovesandby its being sandwiched between a connection-side insulatorand an opposite-side-of-connection insulator, the insulatorsandhaving groovesandat roots of the shoesand, respectively, along both side endsof the front portion of the tooth
