ABSTRACT:
A brushless DC micromotor made up of a stator coil and a rotor housed inside thereof with magnet poles formed therein, which micromotor is characterized in that the stator coil is formed by coaxially winding more than one coil sheet formed on an insulating sheet, on which coil sheet a plurality of coil patterns are continuously provided in series in the direction of winding. The motor of the present invention can be made smaller, thinner and lighter than the conventional counterpart made by the use of a wound copper wire coil.
