摘要： A percussion tool comprises a housing and an electric motor positioned within the housing. The motor has a nominal outer diameter of up to about 80 mm and is operable to output at least about 2760 W. The percussion tool further comprises a battery pack supported by the housing for providing power to the motor. The battery pack includes a plurality of battery cells having a nominal voltage of up to 80 Volts and a sustained operating discharge current of between about 40 A and about 60 A. The percussion tool further comprises a percussion mechanism driven by the motor and including a striker supported for reciprocation in the housing. The percussion tool has a ratio of impact energy to mass that is greater than or equal to 2.5 Joules/kilogram.

摘要： A method for reducing vibrations in a percussion tool includes activating, using an electronic controller of the percussion tool, the motor of the percussion tool, determining, using the electronic controller, that the percussion tool is in a loaded condition, and operating, using the electronic controller, the motor in accordance with a predetermined profile in response to determining that the percussion tool is in the loaded condition. The method also includes determining, using the electronic controller, that the percussion tool is in a no-load condition and operating, using the electronic controller, the motor with reduced speed in response to determining that the percussion tool is in the no-load condition.

摘要： A percussion tool comprises a housing, an electric motor positioned within the housing, a percussion mechanism driven by the electric motor and including a striker supported for reciprocation in the housing, a battery pack removably coupled to the housing for providing power to the electric motor when coupled to the housing, and an electronic controller including an electronic processor and a memory. The electronic controller is coupled to the electric motor and configured to activate the motor and determine whether the percussion tool is in a loaded condition. In response to determining that the percussion tool is in the loaded condition, the electronic controller is configured to operate the motor in accordance with a predetermined profile and in response to determining that the percussion tool is in a no load condition, the electronic controller is configured to operate the motor at a no-load speed.

摘要： A percussion tool includes a housing, a percussion mechanism including a striker supported for reciprocation in the housing along a first axis, and an anti-vibration system for attenuating vibration in a direction of the first axis. The anti-vibration system includes a linkage coupling the percussion mechanism to the housing. The linkage permits relative movement between the housing and the percussion mechanism along the first axis. The anti-vibration system also includes a counterweight supported by the percussion mechanism for relative movement therewith along a second axis that is parallel with the first axis. The counterweight reciprocates out of phase with the striker to attenuate vibration in the direction of the first axis.
