Title: Rolf Benzing: Innovator in Electric Tool Technology
Introduction
Rolf Benzing is a notable inventor based in Neuffen, Germany. He has made significant contributions to the field of electric tools, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Rolf Benzing's latest patents is for a cordless dual-battery electric tool. This invention features a housing that forms a pair of battery mounts, an electrical motor, and circuitry that connects the batteries in series with each other and across the motor. A cutoff switch is integrated to disconnect the motor from the batteries when necessary. Additionally, control circuits monitor the charge levels of the batteries and activate the cutoff switch when the charge drops below a predetermined threshold. Light-emitting diodes indicate which battery is below its permissible charge.
Another significant patent is for an overload protection arrangement for an electric motor, particularly for hand-held power tools. This arrangement includes an electronic speed control that is managed by an overload circuitry. A positive temperature coefficient resistor is situated in the winding of the electric motor, which helps to prevent overheating. When the winding temperature exceeds acceptable levels, the maximum current drawn by the motor is reduced, ensuring that the motor does not burn out. This design allows for rapid cooling of the device powered by the electric motor.
