    摘要: A magnetic drill is provided with an alternate power source. The drill is comprises of: an electric motor for driving a tool; a controller configured to receive an AC input signal and operable to control a drive signal to the electric motor; an electromagnet arranged in a base of the drill housing and operable, in response to a DC voltage, to magnetically couple the base to a surface proximate to the base; an AC/DC converter configured to receive the AC input signal and operates, independent from the controller and in the presence of the AC input signal, to output a DC voltage to the electromagnet; and an alternate power source circuit that monitors the DC voltage output by the converter and, in the absence thereof, provides an alternate DC voltage to the electromagnet.

    摘要: A magnetic base for selectively magnetically latching to a ferromagnetic surface includes a magnet holder, a fixed magnet assembly supported within the magnet holder, a movable magnet assembly supported within the magnet holder, and a transmission. The transmission includes an input, an output coupled to the movable magnet assembly for moving the rotatable movable assembly relative to the fixed magnet assembly through a predetermined range of motion, and a plurality of transmission elements positioned between the output and the input. The transmission elements are configured to provide a variable mechanical advantage between the output and the input during at least a portion of the predetermined range of motion.

    摘要: A power tool including a braking and control circuit. The braking and control circuit includes a microcontroller-based control means circuit. The microcontroller assures control of switch means, such as triacs, switches and relays, and ensures that braking is effectuated regardless of the phase in the power cycle of the alternating current. Also, the microcontroller is programmable so that the braking and control circuit accommodates different braking conditions for different power tools and accommodates combinations of braking conditions for the same power tool. Further, the microcontroller is programmable to configure the braking and control circuit so that the braking force applied to the motor and the stopping time of the motor are regulated and adjustable. This may be accomplished by outputting a control signal so that the switch means skips cycles in the alternating current or by otherwise adjusting the operation of the switch means.

    摘要: A mobile power tool operating assembly for performing material treatment operations, such as drilling, has permanent magnet means to mount the power tool on a ferromagnetic workpiece, and release means to permit release of the magnet means for repositioning of the tool. The release means comprises a screw threaded jack which tilts the assembly so as to overcome the magnetic attraction. The tool can then be repositioned and lowered to its normal working attitude.
