Abstract:
1. An electric motor comprising a stator, wherein the stator includes: the insulator has first flange sections, each of which corresponds to a front end part of each of the tooth sections, second flange sections, each of which corresponds to an intermediate part of each of the tooth sections, and third flange sections, each of which corresponds to a base part of each of the tooth sections, the insulator has first bobbins and second bobbins, a pair of the first bobbin and the second bobbin are axially formed on each of the tooth sections, each of the first bobbins is formed between the first flange section and the second flange section, each of the second bobbins is formed between the second flange section and the third flange section, the insulator has notches formed on the output shaft side and the opposite side thereof, the notches are formed in each of the second flange sections and the third flange sections, the insulator has groove sections, which are formed on the output shaft side and the opposite side, each of which is formed between the second flange section and the third flange section and which correspond to the tooth sections and extended in the axial directions thereof, each of the groove sections makes the notches of each pair of the second flange section and the third flange section communicate with the first bobbin, and a coil cable, which is wound on the first bobbins as the first coils, has connection parts, the connection parts are respectively extended from a winding-start point of the first coil wound on each of the first bobbins and a winding-termination point thereof, for parallel winding, through the groove section located on the inner side of the second coil wound on each of the second bobbins so as not to interfere with the second coil.
