摘要： An excitation circuit (10) for a flux switching motor (14). The circuit includes a low-value film capacitor across the DC side of a bridge rectifier. A plurality of electronic switches are arranged in an H-bridge configuration for switching current flow through an armature winding of the motor in accordance with a PWM control scheme and single-pulse control scheme controlled by microcontroller (18). A start-up diode is placed across the field winding of the motor and is electronically switched out of the circuit after a startup phase of the motor has completed. The circuit implements armature energy recirculation through the field winding during startup to promote more uniform and quicker startup of the motor. The use of a film capacitor improves the power factor of the circuit, helps to eliminate the introduction of harmonics into the AC voltage source, and helps in mitigating EMI. Reverse commutation is used to bring the motor to a quick stop when it is powered off.

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 control scheme employed by the power tool may initiate different protective operations for different tool conditions.

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 driving tool, such as a fastening tool, with a driver (28), motor (32), a flywheel (34) driven by the motor, an actuator (44), an actuator member (38) that is movable by the actuator, a trigger switch that is moveable by a trigger between an unactuated state and an actuated state, and a contact trip switch that is moveable by a contact trip between an unactuated state and an actuated state. The controller does not include power switches for controlling the operation of the motor and the actuator, but rather employs microswitches and control logic to determine when to activate the motor assembly and the actuator.

The low profile power tool uses a low profile motor having a diameter to lamination height ratio of at least 2:1. In an aspect of the invention, the motor is an electronically commutated "pancake" style motor. In an aspect of the invention, the power tool is a random orbital sander or an orbital sander having a motor that provides at least 40 watts of power. In an aspect of the invention, the sander has a mechanical brake that brakes the orbital mechanism and the motor is dynamically braked. In an aspect of the invention, the motor is an electronically commutated motor and a motor controller for it changes the speed of at which it runs the motor from an idle speed to a sanding speed upon the motor speed dropping from idle speed to an idle speed threshold value and changes the speed at which it runs the motor from sanding speed to idle speed upon the motor speed increasing from sanding speed to a sanding speed threshold value.
