Abstract
A power tool system includes a power tool having a tool housing. The tool housing includes a battery pack receptacle having a set of tool terminals. A brushless motor includes an output shaft operably coupled to drive a tool element, a stator having an outer diameter of approximately 60 mm to approximately 80 mm, and a stack length of approximately 75% to approximately 125% of the outer diameter of the stator. A controller is operably connected to the set of tool terminals and to the brushless motor to control power delivery to the brushless motor. A battery pack includes a battery pack housing connectable to the battery pack receptacle on the tool housing and a set of battery cells. The set of battery cells includes at least 15 battery cells each having a nominal voltage of approximately 3.6V and an impedance of approximately ≤13 mΩ. A set of battery pack terminals is connectable to the set of tool terminals. The battery pack has a nominal voltage of at least approximately 54V and the brushless motor is operable under load to output a power of between approximately 3000 W and approximately 5000 W.
