Title: Norbert L Schmitz: Innovator in Alternator Technology
Introduction
Norbert L Schmitz is a notable inventor based in Middleton, Wisconsin, recognized for his contributions to alternator technology. With a total of four patents to his name, Schmitz has made significant advancements in the field of electrical engineering, particularly in the design and functionality of synchronous alternators.
Latest Patents
Schmitz's latest patents include an innovative alternator excitation system. This system features an exciter with a stator that comprises first and second sets of field coils, which are coupled to a source of DC power and in series with the polyphase AC output current generated by the main generator. The design allows for a base level of exciter field current to be provided by the DC current delivered to the first set of field coils, while a second variable amount of field current is supplied by the AC output current to the second set of field coils. Additionally, the exciter includes a rotor structure with armature windings that develop exciter currents in response to rotor movement within the magnetic fields created by the field coils. This innovative approach improves transient response and reduces the overall length and weight of the generator package.
Another significant patent by Schmitz is the main field current transient control circuit for dynamoelectric machines. This invention addresses the challenges faced in synchronous generator-motor systems, where transient currents in the main field windings can occur during load removal and motor start-up. By utilizing a resistive circuit controlled by a transistor switching network, the effects of these transient currents are substantially reduced, enhancing the reliability and efficiency of the system.
