摘要： A power tool is provided including a brushless motor having a rotor and a stator. A power supply interface is arranged to selectively receive a first power input from a first power supply having a first nominal voltage and a second power input from a second power supply having a second nominal voltage, where at least the first nominal voltage does not fall within approximately the operating voltage range of the motor. A motor control circuit is provided including a power switch circuit having power switches that supply electric power from at least one of the first power input or the second power input to the motor, and a controller that controls a switching operation of the power switches to optimize the supply of electric power from the first power input at a level corresponding to the operating voltage range of the motor.

摘要： A power tool is provided including an electric direct-current (DC) motor. A power supply interface is arranged to receive at least one of Alternating Current (AC) power from an AC power supply having a first nominal voltage, or Direct Current (DC) power from a DC power supply having a second nominal voltage. The power supply interface outputs the AC power via an AC power line and the DC power via a DC power line. A motor control circuit supplies electric power from one of the AC power line or the DC power line via a common node.

摘要： A power tool is provided including a power supply interface receiving a removable battery pack, a brushless direct current (BLDC) motor including a rotor and a stator, and a multi-phase inverter bridge circuit. A controller is provided to output drive signals to the inverter bridge circuit to control flow of current from to the motor, where each drive signal is activated within each corresponding phase of the motor within a conduction band. The controller is configured to control a length of the conduction band at a variable value within a first torque range below a torque threshold and at a substantially constant value within a second torque range above the torque threshold. The torque threshold is greater than approximately 1 Newton-meters and the motor produces a maximum power output of at least approximately 1250 watts at the torque of approximately 1 Newton-meters.

摘要： A power tool is provided including a brushless electric motor, a switching arrangement having motor switches and interposed between the electric motor and a power supply, and a controller configured to control a switching operation of the motor switches for driving the electric motor and enforce a current limit on the current delivered to the electric motor. The controller receives a measure of current passing from the power supply to the switching arrangement and takes corrective action to reduce current delivered to the electric motor if the measured current exceeds the current limit. The controller further receives a signal corresponding to at least one of a type and/or a nominal voltage of the power supply and sets the current limit based on the received signal.

摘要： A power tool is provided including a brushless motor having a rotor and a stator. A power supply interface is arranged to selectively receive a first power input from a first power supply having a first nominal voltage and a second power input from a second power supply having a second nominal voltage, where the second nominal voltage is less than the first nominal voltage. A motor control circuit is provided including a power switch circuit having a power switches disposed between the power supply interface and the motor, and a controller outputting drive signals to the power switches within each phase of the motor to control power supplied to the brushless motor from the power supplies. Each phase is associated with a conduction band (CB). The controller sets the conduction band for each phase to a first CB value when receiving power from the first power supply and to a second CB value that is less that the first CB value when receiving power from the second power supply.

摘要： A method is provided for identifying a battery pack that is operably coupled to a battery charger. The method comprises: measuring voltage at a plurality of designated terminals of a first battery pack while the battery pack is coupled to the battery charger; determining how many of the designated terminals are connected to a reference voltage, such as battery positive; and identifying an attribute of the battery pack based on how many of the designated terminals are connected to the reference voltage.
