摘要： The present invention offers a commutation assembly for an electrical motor, whereby a constant optimal pressure is maintained upon the commutator of the motor. This is accomplished by a commutation assembly comprising a torsion brush spring apparatus situated adjacent to a brush unit, the torsion brush spring apparatus generally comprising a spring element with a first end, a coiled center section, and a second end; the spring element having its coiled center section encircling and pivoting about a projection from the motor plate, the projection placed a certain distance D1 from the brush center line and a distance D2 above the lower edge of the brush; a first end extending towards the upper edge of the brush unit and applying a certain force Fx on the upper edge of the brush; and a second end abutting a portion of the motor casing; the brush unit generally comprising a brush having an upper edge in contact with the first end of the spring element and a lower edge in contact with the commutator; the brush unit also comprising a brush holder having a first exterior wall, a second exterior wall, a stop, an end and an aperture; wherein the brush holder, which is situated above the commutator allowing the brush to move longitudinally within the aperture to make contact with the commutator, provides a constant optimal pressure against the commutator due to the constant resulting force applied by the spring element on the brush.

摘要： A table saw such as a chop saw, a miter saw, compound miter saw or a sliding compound miter saw that is provided with a laser arbor alignment system. An opaque shield or transparent shield having an opaque mask blocks the laser beam from being projected into a range of normal operator eye positions. One or more openings in the shield or opaque mask provide a sight line on a workpiece initially. As the saw is moved into engagement with the workpiece, the shield is pivoted away from the workpiece and a solid laser line is projected on the workpiece.

摘要： A feed rate control system may provide feedback to the power tool operator that may assist the operator to obtain consistently high quality output. The feed rate control system may also automatically output a feed rate control signal, optionally influenced by the operating mode of the power tool. In a planer, for example, the feed rate control system may execute different control techniques depending on whether the planer is in ‘finish’ mode or ‘dimension’ mode.

摘要： An orbital sander is provided having a number of novel features including a high speed permanent magnet DC motor having a relatively flat rpm versus torque curve. The sander includes an AC to DC power supply, a remotely located on/off switch operated by a switch actuator bar extending transversely through the housing enabling the operator to actuate the on/off switch by alternatively pushing opposed ends of the actuator bar. The orbital sander further includes a fan having non-uniformly spaced blades, eliminating the need for a conventional counterweight, and a dust outlet adapted to be alternatively connected to a dust canister or alternate size collector vacuum hoses.
