A power tool is provided including a housing defining a cavity therein, where the housing includes a motor case and a handle portion extending along a longitudinal axis of the housing from the motor case; an electric motor having a drive shaft and mounted within the motor case; a partitioning wall extending radially and separating the motor case portion from the non-motor case portion of the housing; and a bearing pocket with an open end facing the motor case portion formed in the partitioning wall and a main body extending away from the electric motor for receiving a rotor bearing. The handle portion includes two elongate walls extending from the partitioning wall, a circuit board supported by the two elongate walls and including a motor drive circuit, and two covers secured to the two elongate walls to cover the circuit board.

Handheld power tool with brushless electric motor

A power tool is provided including a motor case and a handle portion. An electric motor having a drive shaft is mounted within the motor case. A circuit board is disposed in the handle portion to accommodate a motor drive circuit. The motor drive circuit includes a rectifier configured to receive an alternating current from an alternating current (AC) power source and convert it to a direct current supplied to a DC power bus, and a bridge circuit having motor switches connected between the rectifier and the electric motor. A bus capacitor is mounted on the circuit board and coupled across the DC power bus. An auxiliary capacitor having higher capacitance than the bus capacitor is switchably coupled across the DC power bus. The handle portion includes a support member protruding radially outwardly to accommodate the auxiliary capacitor.

Handheld grinder with brushless electric motor

A table saw has a base assembly, a table assembly supported by the base assembly, the table assembly, and a saw assembly supported by at least one of the table assembly and the base assembly. The saw assembly has a saw blade extending through the table assembly. The base assembly has at least one foot having a substantially horizontal surface, a substantially vertical surface, and a curved surface disposed between the substantially horizontal surface and the substantially vertical surface. The substantially vertical surface is substantially coplanar with a surface of the table assembly so that the table saw can be disposed on the substantially vertical surface and the surface of the table assembly.

Portable vacuum

A power tool is provided including a housing, a motor disposed within the housing, an on/off switch having a contact tip disposed within the housing for activating the motor, a paddle switch coupled to the housing via a pivot member and having a paddle trigger engageable by a user, a switch contact lever disposed in selectable engagement with the contact tip of the on/off switch to activate or deactivate the on/off switch, and a biasing member disposed between the switch contact lever and the paddle switch to absorb a travel distance of the paddle trigger with respect to the switch contact lever.

Paddle switch

A handheld grinder includes an elongated housing, an electric motor, an output shaft, a wall, a planar circuit board, and a motor drive circuit. The elongated housing defines a cavity therein and includes a motor case disposed at a front end and a handle portion to a rear end. The electric motor has a drive shaft that is mounted within the motor case. The output shaft is drivably coupled to the drive shaft of the electric motor. The wall separates the cavity between the motor case and the handle portion of the housing. The planar circuit board disposed in the handle portion of the housing. The motor drive circuit is accommodated entirely within the handle portion of the housing on the planar circuit board.

Power tool with separate motor case compartment

A power tool is provided including an elongated housing. The housing includes a motor case disposed at a front end thereof and a handle portion extending along a longitudinal axis of the housing from the motor case to a rear end of the housing. The handle portion includes two elongated walls extending from the motor case along the longitudinal axis of the housing to form a planar opening within the handle portion. A partition wall is arranged along an axis substantially perpendicular to the longitudinal axis of the housing, separating the handle portion from the motor case. An electric motor having a drive shaft is mounted within the motor case, and a module casing supporting a planar circuit board is received within the planar opening and supported by the elongated walls within the handle portion of the housing axially along the longitudinal axis of the housing.

A handheld grinder includes an elongated housing, an electric motor, an output shaft, a wall, a planar circuit board, and a motor drive circuit. The elongated housing defines a cavity therein and includes a motor case disposed at a front end and a handle portion to a rear end. The electric motor has a drive shaft that is mounted within the motor case. The output shaft is drivably coupled to the drive shaft of the electric motor. The wall separates the cavity between the motor case and the handle portion of the housing. The planar circuit board is disposed in the handle portion of the housing. The motor drive circuit is accommodated entirely within the handle portion of the housing on the planar circuit board.

A power tool (e.g., a pneumatic tool) includes a tool housing, a motor disposed in the tool housing, and a switch coupled to the tool housing and configured to control operation of the motor. A light unit includes a light unit housing removably coupleable to the tool housing. The light unit includes a light disposed in the light unit housing, a controller, and a sensor. The sensor is configured to sense actuation of the switch, and the controller is configured to cause the light to turn on when the sensor senses that the switch is actuated.
