Abstract
A power tool contains a brushless motor that includes a stator having a stack thickness and an outer diameter, a rotor having a diameter, and a motor shaft extending from the rotor and having a rotational axis. A drive mechanism is operably coupled to the motor shaft and is configured to drive a tool accessory in relation to a drive axis. A first housing houses the motor and the drive mechanism. The drive axis does not intersect the brushless motor, but the rotational axis of the motor shaft intersects the drive axis. The outer diameter of the stator is at least five times greater than the stack thickness. Furthermore, the diameter of the rotor is greater than the stack thickness.
