    摘要： A power tools incorporates a brushless or electronically commutated drive motor (BLDC). A number of drive trains are provided for connecting the BLDC to the drive shaft of a working tool, such as a rotary saw blade. In one aspect, the BLDC motor is disposed within an arm assembly of a power tool and provides power to the drive shaft of the tool through a gear train that minimizes the size and profile of the power tool.

    摘要： A braking system for a universal motor having field windings includes a motor control circuit connecting the field windings to an external power supply, an energy storage device connected to the motor control circuit across the field windings, and a controller operably coupled to the motor control circuit and configured in a braking mode to disconnect the field windings from the external power supply and to connect the energy storage device to the field windings to produce a braking torque in the motor. The motor may further include brake windings that are selectively connected by the controller to a second energy storage device in the braking mode so that the braking torque is generated by both the field windings and the brake windings.

    摘要： A support frame for a power tool includes a top configured to support a table top and a bottom arranged opposite and parallel to the top. The bottom is configured to support the support frame on a surface when the support frame is in a first position. The support frame further includes a side arranged between the top and the bottom and configured to support the support frame on the surface when the support frame is in a second position. When the support frame is in the first position and the second position, the table top is spaced apart from the surface.

    摘要： An airflow management system for a table saw includes an elongated hollow member and a dust cap. The elongated hollow member includes a first prong and a second prong, the first and second prongs being configured to be positioned adjacent a saw blade on opposite sides of a saw blade plane in which the saw blade is positioned. The first and second prongs define an opening and a partially enclosed space, in which an airflow channel is defined, therebetween. The dust cap is attached to the elongated hollow member and includes a hose connection fluidly connected to the airflow channel of the elongated hollow member and configured to connect to a vacuum source to pull air from the airflow channel through the hose connection.

    摘要： An improvement for a power tool having a motor-driven working tool for performing an operation on a workpiece includes a material sensor positioned to sense the workpiece prior to operation by the working tool. The material sensor is configured to determine a material property of the workpiece and to generate a signal in response thereto. A processor coupled between the material sensor and the motor is configured to control the motor in response to the signal generated by the material sensor.

    摘要： A table saw includes a lower guard assembly, a first airflow fan, a motor, and a drivetrain system. The lower guard assembly has a dust exhaust chute and is configured to at least partially enclose a lower portion of a saw blade. The first airflow fan is positioned in the lower guard assembly and is configured to produce a first airflow directed through the lower guard assembly toward the dust exhaust chute. The motor is configured to rotationally drive an output shaft, and the drivetrain system connects the output shaft to the first airflow fan and the saw blade to enable the motor to rotationally drive the first airflow fan and the saw blade simultaneously.
