Abstract
A power tool includes a motor () having a stator (), a rotor () and three terminals (). The stator includes a tubular stator core () having six teeth (), first and second electrically insulating members () affixed to the stator core, and six coils () wound around the teeth such that three phases are defined. The three terminals are held by the first electrically insulating member and are respectively electrically connected to the three phases. All of the six coils may be formed by winding a single continuous winding wire () sequentially around each of the six teeth. All of the three terminals () may be disposed within a semicircular area of the stator core. At least a first crossover wire portion () of the winding wire may be disposed on the second electrically insulating member.
