Abstract: A method for operating a power tool includes electronically braking a motor shaft of a brushless electric motor using a controller of the power tool. A spindle unit, positioned on the motor shaft, has a known rotational position relative to at least one pole of a plurality of poles of a rotor of the motor shaft. The method further includes stopping the motor shaft, using the controller, in a predetermined rotational position relative to a stator of the electric motor based on a detected position state of a plurality of position states as detected by a plurality of position sensors of the electric motor. The plurality of position states identify a rotational position of the rotor relative to the stator, and at the predetermined rotational position, a spindle lock of the power tool is configured to engage the spindle unit without additional rotation of the motor shaft.

Abstract: A method of operating a power tool includes identifying a performance factor of a battery pack operably connected to the power tool using a controller of the power tool based on coded data received from the battery pack. The method also includes operating an electric motor of the power tool, using the controller, at a first maximum speed when the identified performance factor is greater than or equal to a threshold value, and operating the electric motor, using the controller, at a second maximum speed when the identified performance factor is less than the threshold value. The second maximum speed is less than the first maximum speed.

Abstract: A portable, battery-powered liquid sprayer includes a supply tank assembly, a base assembly, and a wand. The supply tank assembly holds a liquid to be sprayed. The base assembly is selectively coupled to the supply tank assembly. The base assembly receives and supports a motor, a pump that is driven by the motor, and a rechargeable battery that powers the motor. Based on a signal provided by a pressure switch that detects an outlet pressure of the pump, the motor drives the pump to drive the liquid from the supply tank assembly and to eject the liquid from the hose. The battery is removably coupled to the base assembly and is operable to supply power to the motor. A wand is connected to an outlet of the pump via a flexible hose whereby the wand is in fluid communication with the supply tank assembly.

Abstract: A hybrid power supply for power equipment or a power tool is disclosed. The hybrid power supply is advantageously configured to operate in several different operating modes depending on the performance or power requirement of the equipment or tool, as well as depending on whether AC power is available. Particularly, the hybrid power supply enables the equipment or tool to operate using battery power, battery power, or both. Additionally, the hybrid power supply enables charging of attached batteries and enables providing power to an AC accessory connected to the equipment or tool.

Abstract: A gearbox includes a planetary gear assembly, a first gear assembly, and a second gear assembly. The first gear assembly is engaged to provide a first rotational input to the planetary gear assembly when an input shaft is rotating in a first direction and is disengaged when the input shaft is rotating in a second direction. The second gear assembly provides a second rotational input to the planetary gear assembly when the input shaft is rotating in the first direction and provides a third rotational input to the planetary gear assembly when the input shaft is rotating in the second direction.
