Abstract:

An electronic module is provided for a power tool having an electric motor. The module includes a module housing having a radial portion and a cylindrical portion extending from the radial portion away from the electric motor and defining an open end, a printed circuit board (PCB) received within the module housing through the open end thereof, power switches mounted on the PCB, and magnetic sensors mounted on the PCB facing the motor substantially equidistantly from a center of the PCB. The module housing includes openings disposed in the radial portion angularly around a center of the module housing to receive the magnetic sensors therein to allow the magnetic sensors to magnetically interface with the electric motor.

Abstract:

An electronic module is provided for a power tool having an electric motor. The electronic module includes a printed circuit board (PCB) being substantially disc-shaped; power switches mounted on the PCB forming an inverter bridge circuit for driving the electric motor; a controller mounted on the PCB and configured to control a switching operation of the power switches; positional sensors mounted on the PCB substantially equidistantly from a center of the PCB within the control portion and in communication with the controller to provide positional signals related to a rotational position of the electric motor to the controller; and a module housing arranged to receive the PCB therein. The module housing includes a planar portion in parallel to the PCB and openings disposed in the planar portion angularly around a center of the module housing to receive the positional sensors therein.

Abstract:

A power tool is provided including a tool housing and a brushless DC (BLDC) motor disposed within the tool housing. The motor includes a stator assembly and a rotor assembly having a rotor lamination stack mounted on a rotor shaft to rotate therewith. The power tool also includes a power module for driving the motor, which includes: a printed circuit board, power switches operatively connected to the motor disposed on a first surface of the printed circuit board, positional sensors disposed on a second surface of the printed circuit board around a periphery of a center portion of the printed circuit board, and a heat sink having a substantially planar surface facing the second surface of the printed circuit board and disposed between the motor and the printed circuit board. The heat sink includes a through-hole therein sized to axially expose the positional sensors in the direction of the motor.
