摘要： A power tool is provided with a multi-phase brushless motor including a rotor and a stator having stator windings corresponding to at least three phases of the motor. A power switch circuit is provided including high-side and low-side power switches. A power supply interface receives alternating-current (AC) power from an AC power supply or battery direct-current (DC) power from one or more battery packs. A rectifier converts the AC power to a rectified DC voltage on a bus line. A capacitor is disposed across the bus line such that, within each half cycle of the AC power voltage waveform, the power switch circuit draws current from the AC power supply within a first time period and from the capacitor within a second time period, the capacitor having a capacitance value such that the first time period is greater than the second time period.

摘要： A power tool is provided including an electric universal motor configured to operate within an operating voltage range of approximately 90V to 132V. 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, where the first and second nominal voltages fall approximately within the operating voltage range of the motor. The power supply interface is configured to output 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 to the motor such that the motor brushes are electrically coupled to one of the AC or DC power supplies.

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 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 is further configured to initiate a protective response if a number of time intervals in which the measured current exceeds the current limit exceeds a predetermined threshold.
