A tool operates with a guide system to identify the orientation of a tool on a work piece. In one implementation, the tool identifies its orientation with respect to a guide signal supplied by the guide system. In an alternate embodiment, the tool determines its absolute orientation, such as a (x, y) coordinate. The tool includes an action component adapted to alter the work piece, such as a cutting head in a router. A guide detector in the tool detects a position of a guide signal from the guide system. A location detector in the tool receives the position data and employs it to determine the tool's orientation. Based on the detected orientation, the tool decides whether any tool adjustments are necessary. Examples of tool adjustments include the following: adjusting the position of the action component, enabling or disabling the action component, and providing operating indicators to direct a tool operator's use of the tool.

The invention relates to an automatic field-weakening method for a built-in permanent magnet synchronous motor, which solves the problem that field-weakening speed is difficult to widen due to the fixed rotor excitation and small reactance of armature reaction of a direct axis in the conventional permanent magnet synchronous motor in the market. In a rotor magnetic structure of the permanent magnet synchronous motor, a magnetic flux short-circuit block is arranged in a magnetic flux isolating layer in a quadrature axis direction with the help of an automatic adjustment action of a spring; when the rotary speed of the rotor is low, the short-circuit block is positioned at a low-speed position so that interelectrode magnet leakage through the isolating layer is small; when the rotary speed of the rotor is increased, the short-circuit block gradually deviates from the low-speed position to move towards the edge of the rotor under the action of rotating centrifugal force, which expands the interelectrode magnet leakage path; and the leakage magnet flux passing through the isolating layer is increased and the main magnet flux is reduced so that the aim of automatic filed-weakening widening speed is fulfilled in the motor body and a larger speed-adjusting range is reached. The method can be applied to the permanent magnet motors which have uncertain pole numbers and tangential or radial magnet structures.
