摘要： A system and method for controlling a brushless DC motor (58) is provided. The motor (58) includes a rotor (72) and a stator (96) having at least three phases. The rotor (72) is magnetically coupled to and moveable by the stator (96) when the coils (94) are appropriately energized. Each of the coils (94) is characterized by a corresponding voltage waveform. No more than two position sensors (122) are provided for sensing the position of the rotor (72) during a start-up mode. Each position sensor (122) has an associated position sensor signal. The position sensors (122) are aligned to sense the rotor position such that each position sensor signal indicates a zero torque point corresponding to a phase voltage waveform. The position of the rotor (72) is sensed such that the position sensor signals indicate the start-up operating state of the motor (58). During a first ambiguous start-up state, two predetermined coils (94) are alternately energized. During a defined start-up operating state, one predetermined coil (94) is energized.

摘要： A driving tool, such as a fastening tool, with a driver, a motor, a flywheel driven by the motor, an actuator, an actuator member that is movable by the actuator, a trigger switch that is moveable by a trigger between an unactuated state and an actuated state, and a contact trip switch that is moveable by a contact trip between an unactuated state and an actuated state. The controller does not include power switches for controlling the operation of the motor and the actuator, but rather employs microswitches and control logic to determine when to activate the motor assembly and the actuator.

摘要： A method for operating a driving tool, such as a fastening tool, that has a driver, a motor assembly with a motor and an output member, and an electrical power source. The methodology includes transmitting electrical power to the motor to rotate the output member and thereafter adjusting one or more control parameters if a rotational speed of the output member is not within a predetermined operating range.

摘要： In a cordless power tool system, a battery pack (450) which may removably attachable to a cordless power tool and to a charger may include at least one battery cell (410) and a power limiting device (490). The power limiting device may be arranged in series with the at least one battery cell for limiting power output of the battery pack based on the component that is connected to the pack. Current and hence power out of the battery pack may be controlled as a function of total internal impedance in the battery pack, which may be adjusted depending on the component that is connected to the pack.

摘要： A 'low profile' power tool, wherein a user can grasp the top (105) of the tool with a hand positioned close to the bottom of the tool. The tool uses a motor having a diameter to lamination height ratio of at least 2:1. The motor may be an electronically commutated “pancake” style motor and the tool may be a random orbital sander or an orbital sander having a motor that provides at least 40 watts of power. The sander (100) may have a brake that brake that brakes an orbital mechanism (104) which brakes the motor. The tool may have a controller which changes the speed of the motor from idle to a sanding speed upon the speed dropping from idle to an idle speed threshold value and changes the speed of the speed of the motor from sanding speed to idle upon the speed increasing from sanding speed to a sanding speed threshold value.
