Latest Patents

One of his notable inventions is the "Brush Wear Detection and Warning System." This system is designed to provide an indication that a dynamoelectric machine requires maintenance before the brush wears to the point of damaging the rotor contact surface. The brush includes a wear-detecting wire that senses voltage when the insulation is abraded by contact with the rotor. This innovative design allows for non-latching warning circuits to indicate brush wear effectively.

Another significant patent is the "Permanent Magnet Motor." This motor features a unique design with first and second U-shaped sections made of low reluctance magnetic material. The motor armature shaft passes through a hole in the bight of each section, creating a high reluctance path. The design minimizes the air gap between the armature and the magnets, enhancing the motor's efficiency and performance.
