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 tool housing; at least one battery receptacle accommodated on the tool housing, the battery receptacle being adapted to receive a battery pack having a maximum voltage of at least 60 volts; and a brushless DC (BLDC) motor disposed within the tool housing, the motor including a stator assembly and a rotor assembly rotatably disposed within the stator assembly. A motor control and power module is disposed in close proximity to the motor, including a power switch circuit electrically coupled to the motor and a first controller configured to control a switching operation of the power switch circuit for supply of power from the battery pack to the motor. A battery management control module is disposed in close proximity to the battery receptacle, including a second controller distinct from the first controller, the second controller configured to manage an operation of the battery pack.

摘要： A power tool is provided including a brushless DC (BLDC) motor having a stator assembly and a rotor; a substantially-cylindrical motor housing having an open end for receiving the stator assembly, a rear end, a substantially-cylindrical bearing pocket formed in the rear end to receive the rear bearing of the motor therein, and a radially-extending slot formed at or near its rear end; and a positional sensor board radially received within the slot along a central receiving axis. The positional sensor board includes a curved inner edge shaped to be positioned around the bearing pocket and includes positional sensors mounted around the curved inner edge and facing the rotor to sense a rotational position of the rotor. The curved inner edge is disposed on a side corner of the positional sensor board such that the positional sensor board is asymmetrically-shape in a direction of the receiving axis.

摘要： A power tool is provided including a motor housing having a substantially-cylindrical main body having an open end and a rear end. A brushless DC motor is provided including a stator assembly received through the open end of the motor housing and secured within the main body of the motor housing. A motor control and power module disposed proximate the rear end of the motor housing includes a printed circuit board (PCB) on which power switch and a controller are mounted. A mounting bracket is secured to the motor housing at the rear end to support the module such that the PCB is substantially parallel to the rear end. The mounting bracket includes a mating portion projecting axially to come to contact with the motor housing around the rear end to structurally support the mounting bracket with respect to the motor housing.

摘要： A power tool is configured to receive power from a power supply. The power tool may include a rectifier that may output a rectified signal to a DC power bus. A switching arrangement may operate to deliver electric power from the DC power bus to an electric motor. A switch path may be electrically coupled in parallel with the rectifier on the DC power bus. The switch path includes an auxiliary capacitor in series with a switch and a state of the switch controls a discharging path for the auxiliary capacitor. A switch control circuit may be configured to detect voltage associated with at least one of the AC power supply or the DC power bus and to control state of the switch in accordance with magnitude of the detected voltage.
