摘要： A power tool is provided including a housing including a motor case and a handle; an electric motor housed within the motor case and rotatably driving a motor spindle; a gear case mounted on the housing; and an output spindle rotatably coupled to the motor spindle. The output spindle, motor spindle, and the handle form the plane through the housing. A fan is coupled to the motor to generate an airflow through the housing. The housing includes a first air inlet on a first side of the plane and a second air inlet a second side of the plane opposite the first air inlet, both adjacent the motor. The first air inlet is larger than the second air inlet to allow a larger volume of air to enter the housing from the first side of the plane than from the second side of the plane.

摘要： A power tool is provided including a housing, a brushless direct-current (BLDC) electric motor disposed inside the housing, power switches disposed between a power supply and the electric motor and including high-side switches and low-side switches, and a control unit configured to control a switching operation of the power switches to operate the electric motor and electronically brake the motor by simultaneously activating the high-side switches or the low-side switches to stop the rotation of the motor upon detection of a condition prompting the braking of the motor. The control unit is configured to detect the condition that prompts the braking of the electric motor, set a braking profile for braking the electric motor based on the detected condition, and execute braking of the electric motor using the braking profile.

摘要： 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.
