摘要： Disclosed herein is a battery charger control circuit having a voltage detector to generate a signal indicative of a source voltage level to select one of a first charging mode and a second charging mode, and a charge controller coupled to the voltage detector to enable charging in accordance with one of the first charging mode and the second charging mode based on the signal from the voltage detector. The first and second charging modes establish charging at differing, non-zero rates. The source voltage level may be sampled at a sampling rate to minimize power consumed by monitoring the source voltage level.

摘要： A sensing circuit is useful with a power outlet and a power tool having power supplied thereto via the power outlet. The sensing circuit includes a generator, a transmitter, and a detector. A first signal having a high frequency is developed by the generator and supplied to a first terminal of the power outlet by the transmitter. The detector is coupled to the second terminal of the power outlet and tuned in accordance with the high frequency to develop a second signal indicative of whether the power tool is coupled to the power outlet. The sensing circuit may be used in conjunction with a regulating circuit and a two-position switch useful for controlling the electrical energy supplied to the power tool and a vacuum cleaner having the power outlet disposed thereon.

摘要： A motor is disclosed that operates on either AC outlet power or DC battery power with decreased power drop when switching between AC and DC power. The AC power to the motor may be stepped down by using a clipper circuit, while the DC power supplied to the motor may be increased by switching motor field windings from a series wound circuit to a parallel wound circuit. The motor may be used in a vacuum motor embodiment, or in other consumer devices that utilize electric motors.

摘要： A method for assembling a motor shaft with a bearing, a motor housing, and an impeller is disclosed. A motor shaft extension is used to retain the impeller axially on the motor shaft and allows the motor shaft to drive an additional component, such as an impeller, located a distance from the motor. The motor shaft extension may be fabricated from aluminum or hardened steel. Additionally, the motor shaft extension may be embodied in a tube extending past the end of the motor shaft and a shaft extension pressed into the end of the tube.
