摘要： A power tool is provided, including a housing; a brushless DC (BLDC) motor arranged within the housing, the motor including a stator and a rotor rotatably disposed within the stator; a power module electrically disposed between the motor and a power supply, the power module including power switches; an actuator engageable by a user; and a control module configured to control a switching operation of the power switches to begin supply power to the motor when the actuator is engaged. The control module monitors engagement and disengagement events of the actuator, and ignores a subsequent engagement of the actuator if at least one of number of actuator engagement events and/or number of actuator disengagement events exceeds a predetermined threshold value within a predetermined time.

摘要： The present directed to a cordless power tool system including a plurality of cordless power tools, a plurality of fixed voltage and multi-voltage battery packs and a plurality of battery pack chargers. The battery packs include circuitry to indicate various parameters about the battery pack and communicate this indication to the power tools in order to enable the power tools to alter their motor output schemes to improve performance. The indication may include whether the battery pack is a fixed voltage battery pack or a multi-voltage battery pack and when the multi-voltage battery pack is in a first configuration or a second configuration.
