Abstract: A power tool comprising a power tool housing and a motor within the power tool housing. The motor including a rotor and a stator, the rotor coupled to a motor shaft to produce a rotational output. The power tool further includes a sensor within the power tool housing, the sensor configured to sense a free fall of the power tool, generate an output signal related to the sensed free fall. The power tool further includes a controller including a processor and a memory, the controller configured to receive the output signal from the sensor, detect the free fall of the power tool based on the output signal from the sensor, and brake the motor when the free fall of the power tool is detected.

Abstract: A random orbit sander includes a housing and a motor enclosed within the housing. The motor includes a motor shaft that is rotatable about a first axis. An eccentric carrier coupled to the motor shaft includes a circular internal bore that defines a second axis that is offset from the motor shaft. A bearing is received within the circular internal bore of the eccentric carrier. A sanding pad is supported by the bearing and is rotatable about the first axis in an eccentrically orbiting manner. The motor shaft and the eccentric carrier are integrally formed as a single piece.

Abstract: A belt sander for sanding a workpiece and defining a center of gravity within a first plane. The belt sander includes a housing, a handle defining a second plane, and a drive unit disposed within the housing. The drive unit includes a motor disposed adjacent a first sidewall of the housing, a pulley system disposed adjacent a second sidewall of the housing opposite the first sidewall, and a transmission disposed between the motor and the pulley system. The belt sander further includes a belt drive system driven by the drive unit and including a drive wheel, a driven wheel, and a platen. The platen defines a third plane extending perpendicular therefrom. The transmission and pulley system are disposed on one side of the first plane and the motor is disposed on an opposite side of the first plane. The motor is intersected by the second and third planes.
