Abstract: An electric motor may include a rotor assembly including a rotor shaft. An electric motor may include a stator assembly including a plurality of stator segments arranged adjacent one another in a circumferential direction of the stator assembly, at least one stator segment including a core having a core yoke portion and a core tooth portion, an insulator at least partially covering the core and having an insulator yoke portion and an insulator tooth portion, a stator segment yoke portion formed by the core yoke portion and the insulator yoke portion, a stator segment tooth portion formed by the core tooth portion and the insulator tooth portion, and a stator winding extending about the stator segment tooth portion including a wire lead. The insulator yoke portion includes a standoff portion that defines a wire notch. The wire notch at least partially receives the wire lead.

Abstract: A jigsaw including a housing, a handle extending transverse from the housing in a direction of a handle axis, a battery selectively coupled to the handle, a foot plate coupled to the housing and configured to contact a workpiece, and a drive assembly powered by the battery. The drive assembly includes a motor, a fan, a transmission driven by the motor, and an output spindle driven by the transmission and coupled to a cutting blade. The jigsaw also includes a frame supported within the housing which supports the motor and the transmission. The frame includes a shroud surrounding at least a portion of the fan and an air chute in fluid communication with the shroud that together direct an airflow produced by the fan toward a cutting area adjacent the cutting blade. The jigsaw also includes a baffle that is selectively moveable into the air chute to redirect the airflow away from the cutting blade.
