    Abstract: A power tool (1; 90) includes a motor (17) having a stator (18) and a rotor (19). The stator (18) includes front and rear insulators (21, 22) respectively disposed forward and rearward of a stator core (20) in an axial direction thereof. At least six coils (23) are respectively wound on the stator (18) such that the coils (23) are wound through the front and rear insulators (21, 22). Winding wires (23a) respectively electrically connect circumferentially-adjacent pairs of the coils (23). A short circuiting device (25) short circuits respective pairs of windings (23a) that are located diagonally or diametrically across from one another.

    Abstract: The present application discloses an electric working machine. The electric working machine includes a motor including a stator. The stator includes: a stator core haring a plurality of tooth portions radially extending along a radial direction; and a first coil, a second coil, and a third coil wound on the tooth portions. A start end of the first coil and a finish end of the second coil, a start end of the second coil and a finish end of the third coil, and a start end of the third coil and a finish end of the first coil are led out within a range of 200 degrees from the stator.
