Abstract
A power tool () includes a motor () having a stator () and a rotor (). The stator () includes front and rear insulators () respectively disposed forward and rearward of a stator core () in an axial direction thereof. At least six coils () are respectively wound on the stator () such that the coils () are wound through the front and rear insulators (). Winding wires () respectively electrically connect circumferentially-adjacent pairs of the coils (). A short circuiting device () short circuits respective pairs of windings () that are located diagonally or diametrically across from one another.
