Beschreibung
Zusammenfassung:	A power tool is provided including a housing including a grip portion; and a brushless direct-current (BLDC) motor at least partially disposed within the grip portion of the housing. The motor includes a stator having a rotor core, a rotor, and front and rear bearing support structures. The stator core includes a non-segmented construction with a maximum diameter of approximately smaller than or equal to 34 mm, and a ratio of a motor size (Km) constant of the motor to a length of the motor is in the range of approximately 0.39 to 0.59 (Nmm/√W)/mm. When powered by a 20V battery pack, a ratio of a maximum power output of the motor to a volume of the motor is at least approximately 0.0106 W/mm{circumflex over ( )}3.
