摘要： A battery powered tool includes a housing containing a motor assembly. A fan positioned in the housing is rotated by the motor assembly. The fan has a circular ring/body and further has multiple fan blades directly connected to the circular ring body. The circular ring/body defines a concave shaped surface having the fan blades directly connected to the concave shaped surface. A housing cover includes: first and second extending walls; a slot created between the first and second extending walls; and multiple air intake vents all positioned in a lower housing zone separated from an upper housing zone by the slot. An electronics module is positioned in the housing proximate to the housing cover lower housing zone such that air entering the intake vents passes only through the lower housing zone and past the electronics module to cool the electronics module before entering the fan.

摘要： A control unit for controlling commutation of a brushless direct current (BLDC) motor provided. The control unit controls high-side and low-side switches arranged between a power source and the motor and configured as a three-phase bridge to commutate the motor. The control unit is configured to provide drive signals to drive each of the high-side and low-side switches to control, for each phase of the bridge, a pulse-width modulation (PWM) of one of the high-side or low-side switches. For each phase of the bridge, immediately following a first cycle ending with a falling edge of the drive signal for one of the high-side or low-side switches, the control unit introduces a special commutation edge pulse in the drive signal of the other of the high-side or low-side switches to shunt the current from the motor before turning both the high-side and the low-side switches off during a second cycle.

摘要： An armature for an electric motor has a lamination stack on a shaft with a commutator mounted on one end of the shaft. Magnet wires wound in slots in the lamination stack, the commutator and armature shaft are at least partially encapsulated in thermoset. The commutator has a commutator ring divided into a plurality of segments with slots between the segments that are filled with a second plastic when the commutator is made by molding a core of the second plastic, such as phenolic, in the commutator ring before the commutator ring is mounted on the armature shaft. Prior to molding the thermoset, the commutator ring is sealed. The seal prevents the thermoset from flowing into the slots between the commutator ring segments or over the commutator ring.

摘要： A mode selector switch (800) for a power tool (1) 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 (1040) 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 (600) 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.
