摘要： A power tool is provided including a tool housing, a brushless DC (BLDC) motor assembly disposed within the tool housing, and a power module including a printed circuit board (PCB) and power switches mounted on the PCB and electrically coupled to the motor assembly. The PCB includes a width that is greater than a diameter of the motor assembly. A mounting bracket is secured to an end of the motor assembly and includes a mating portion arranged to mate with the end of the motor assembly, mount posts extending radially-outwardly from the mating portion, and axial walls extending between outer ends of the mount posts and at least partially housing the power module to support the PCB in a substantially parallel orientation relative to the rear end of the motor assembly.

摘要： A power tool is provided including a housing, a brushless motor disposed within the housing, a power switch circuit that supplies power from a power source to the brushless motor, and a controller configured to receive at least one signal associated with a phase current of the motor, detect an angular position of the rotor based on the phase current of the motor, and apply a drive signal to the power switch circuit to control a commutation of the motor based on the detected angular position of the rotor. If the supply of power to the motor is turned OFF to cause the motor to slow down and is turned back ON while the rotor speed exceeds a speed threshold, the controller electronically brakes the motor for a time interval to measure the phase current of the motor and detects the angular position of the rotor based on the measured phase current.

摘要： A power tool includes a multi-phase BLDC motor, a plurality of switches, an input unit, and a controller. For each phase, the controller operates to vary power output to the motor between a first power and a second power by varying a duty cycle of a PWM signal from 0% to 100% while keeping a conduction band (CB) of corresponding motor switches and/or an advance angle (AA) at a predetermined value when the input unit moves between a first position and a predetermined position between the first and a second position. For each phase, the controller operates to increase the power output by the motor to greater than the second power by increasing the CB/AA to greater than the predetermined value while keeping the duty cycle of the PWM signal at 100% when the input unit moves between the predetermined position and the second position.

摘要： A power tool system includes a tool body with a motor having an output member that drives an accessory. The output member defines an output member axis. An end effector is coupled for rotation with the output member relative to the tool body. The end effector is configured to retain the accessory. A light source is disposed on the end effector. A consumable tool, such as a holesaw, is removably attachable to the end effector, and has an illumination opening configured to be substantially aligned with the light source. The holesaw may have a generally cylindrical side wall and a base wall that defines a central opening for receiving an arbor, an aperture spaced radially outward by a first distance for receiving a projection on an arbor and an illumination opening spaced radially a second greater distance.
