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.

摘要： A power tool may include an electronically commutated motor such as, for example, a brushless DC permanent magnet motor with a rotor having internally mounted magnets. A control system may be used to control the motor in a manner that implements field weakening when the speed of the motor increases beyond its rated motor speed, or when the torque demands on the motor continue to increase after the maximum power output of the motor is reached. The field weakening may offset the growing back EMF and may enable a constant power and constant efficiency to be achieved by the motor over a wide speed range, rather than at just a single predetermined operating speed. Pulse width modulation control of the motor may be used up until the motor reaches its maximum power output.

The motor has a rotor having permanent magnets mounted in recesses in a back iron of the rotor. In one embodiment the motor has three phase windings, each having at least a pair of coils. The phase windings are connected in either a delta or a wye configuration via electromechancial or electronic switching components, or a combination of both, by a controller within the tool. The coils in each phase winding can also be switched between series and parallel configurations to configure the motor to provide its various operating modes. In one embodiment a dual wound moto is disclosed that has its phase coils dynamically or statically switchable between series and parallel configurations.

摘要： A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The controller may opt to reduce the torque applied to shaft to a non-zero value that enables the operator to regain control of the tool.
