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 brushless direct-current motor is provided includes an inner stator and an outer rotor. A rotor shaft extends through a stator core of the inner stator. A first end cap includes a radial back plate disposed on a first side of the stator and a front center opening through which the rotor shaft is supported via a front bearing. A second end cap includes an inner annular body extending axially inwardly and forming a rear center opening, an outer annular body, and a main body extending on a second side of the stator. The inner annular body includes a first portion that extends at least partially into an opening of the stator core and supports the rotor shaft via a rear bearing, and a second portion rearward of the first portion that received a rear end of the rotor shaft therein and houses a sensor board therein.

摘要： A power tool motor is provided including a stator assembly and a rotor assembly rotatably disposed within the stator assembly. The stator assembly includes: a generally-cylindrical lamination stack having a stator ring and stator teeth extending radially inwardly towards a center bore arranged to receive the rotor assembly therein; an end insulator disposed at an and of the lamination stack and having an outer ring and teeth portions extending radially inwardly from the outer ring towards a center of the end insulator; and stator windings wound around the stator teeth and the teeth portion of the end insulator. A generally cylindrical seal member is disposed to interface with an end of the stator, which includes a mating surface having indents configured to mate with ends of the stator windings or ends of the teeth portion of the end insulator to substantially seal respective gaps therebetween from entry of workpiece particulate.

摘要： A stator for a brushless DC (BLDC) motor includes a stator core having stator teeth extending radially inwardly towards a center bore, stator windings respectively wound around the stator teeth, and insulating inserts having substantially the same longitudinal length as the stator core. The insulating inserts are longitudinally received between adjacent stator windings at or near inner tips of the adjacent stator teeth to substantially seal the center bore of the stator assembly from the stator windings.

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 brushless direct-current motor is provided includes an inner stator and an outer rotor. The rotor includes a rotor core disposed around the stator, an inner annular member mounted on a rotor shaft, and a plurality of radial blades extending angularly from the rotor core to the inner annular member forming a fan. A first end cap is provided including a radial back plate proximate the fan and a center opening in the radial back plate through which the rotor shaft extends. A second end cap is provided including a main body disposed adjacent the stator opposite the fan. The radial back plate of the first end cap includes at least one sloped surface forming at least one air gap such that the airflow generated by the fan is centrifugally guided within the first end cap by the sloped surface and caused to exit through the air gap.
