Title: The Innovations of Kenneth A. Benjamin
Introduction
Kenneth A. Benjamin is a notable inventor based in Greensboro, NC (US). He has made significant contributions to the field of motor control technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Stall protection circuit for brushless motor control." This invention relates to a stall shutdown circuit for a brushless direct current motor, which controls the energization of the motor's stator windings using transistors. By implementing this stall shutdown circuit, the power supply transistor's capacity can be reduced to one-third of the current requirement, significantly lowering the motor's cost. This technology is particularly beneficial in textile machines, such as take-up devices, where stopping a spindle to change yarn packages is essential.
Another significant patent is the "Take-up machine motor control." This invention pertains to a take-up machine used in fiber or yarn production, where the produced fiber or yarn is wound onto spools or tubes. The control mechanism varies the speed of an electric motor driving the spindle, actuated by the position of a compensator arm connected to a linear voltage differential transformer. This setup effectively manages current flow through an NPN power transistor, which in turn regulates the speed of a three-phase AC motor.
