Abstract
An electric motor designed for electric tools. The motor includes a first molded coil having a first coil covered entirely with a resin that is electrically insulating and highly heat conductive. The motor also includes a second molded coil having a second coil covered entirely with the resin. The first molded coil has a pair of first axial portions, and the second molded coil has a pair of second axial portions in alignment with the first axial portions. A stator core disposed around the molded coils includes a first stator core and a second stator core with first stator core legs and second stator core legs, respectively. Air paths through which fan airflow passes are formed between the axial portions and the opposing stator core legs.
