摘要： A mode selector switch for a power tool that can have a source of a magnetic field and use a magnetoresistive component to produce an output signal that changes when the strength of the magnetic field changes. The power tool can have a microprocessor that changes an operational mode of the power tool based on a change of the output signal from the magnetoresistive component. The magnetoresistive component can be a Hall effect sensor and the power tool can be a nailer. The power tool can have a switching means which changes an operational mode based upon a change in the strength of the magnetic field upon a magnetoresistive component. A method of controlling a power tool, having a step of changing an operational mode of a power tool based upon identifying a change in output from a magnetoresistor.

摘要： A control unit for a brushless DC motor of a power tool having a rotor and a stator is provided. The control unit detects an initial position of the rotor, commutates the motor beginning at the initial position of the rotor using a low-speed motor commutation scheme until an output speed of the rotor exceeds a speed threshold, and commutates the motor based on a back-electromotive force (back-EMF) voltage of the motor after the output speed of the rotor exceeds the speed threshold. In the low-speed commutation scheme, the control unit applies a first set of voltage pulses to a present sector and a second set of voltage pulses to a next sector, and detects a transition of the rotor from the present sector to the next sector based on motor current measurements associated with the first set of voltage pulses and the second set of voltage pulses.
