Beschreibung
Zusammenfassung:	A power tool is provided including a tool housing including a motor housing and a handle portion; a battery receptacle disposed at an end of the handle portion opposite the motor housing, the battery receptacle being configured to receive a battery pack having a maximum voltage of at least 60 V; and a brushless DC (BLDC) motor including an electronically-commutated stator assembly and a rotor assembly magnetically interacting with the rotor assembly to rotate with respect to the stator assembly, the stator assembly comprising a stator lamination stack sized to be received within the motor housing having a circumference of approximately 140 to approximately 190 mm. The motor produces a maximum power output of at least 1600 watts for driving an output shaft at a maximum torque of at least 30 inch-pounds and a maximum speed of at least 8000 rotations-per-minute.
