Latest Patents

One of Schultz's latest patents is for a segmented magnet dynamoelectric machine with a series-connected rotor. This invention features a circumferentially segmented stationary magnetic field structure that provides magnetic poles, including diametrically opposed pairs of north and south poles. The rotor conductors are designed to extend longitudinally and are selectively interconnected in sets, creating multiple series current paths that traverse various stator active pole regions. Additionally, the machine includes a pair of brushes for current collection at one or both ends.

Another significant patent by Schultz is a switching circuit for high current brushes in a dynamoelectric machine. This circuit is electrically connected to a brush and collector bar of a DC dynamoelectric machine. It utilizes a high current rectifier and a source of electromotive force, producing a current in the circuit that is generally equal to the current flowing between the brush and the collector bar. This design can be forced to zero as the brush separates from the collector bar, reducing degradation of the trailing edges of the brushes and collector bars, ultimately improving machine efficiency.
