    摘要: A portable band saw includes a serviceable/replaceable bumper system for allowing the band saw to be easily repaired if damaged from being dropped. An auxiliary handle is adjustably mounted to the band saw and is releasable from its position if subjected to a large force so as to avoid damage to the handle and tool housing. An adjustable guide shoe includes a toolless adjustment. The front and rear section of the band saw are disposed on opposite sides of a polymeric field case. Compression rods are used to isolate compression forces from the polymeric field case. An electric box assembly including a plastic component box is disposed between the field case and a front section of the band saw. A crash guard is mounted adjacent to the field case and includes a sight guide along an edge thereof and a rear blade guard formed integrally therewith.

    摘要: A power tool is provided including a tool housing and a brushless DC (BLDC) motor disposed within the tool housing. The motor includes a stator assembly and a rotor assembly having a rotor lamination stack mounted on a rotor shaft to rotate therewith. The power tool also includes a power module for driving the motor, which includes: a printed circuit board, power switches operatively connected to the motor disposed on a first surface of the printed circuit board, positional sensors disposed on a second surface of the printed circuit board around a periphery of a center portion of the printed circuit board, and a heat sink having a substantially planar surface facing the second surface of the printed circuit board and disposed between the motor and the printed circuit board. The heat sink includes a through-hole therein sized to axially expose the positional sensors in the direction of the motor.
