He holds five patents that showcase his innovative approach to engineering and technology. His work primarily focuses on enhancing the efficiency and functionality of mechanical systems.
Latest Patents
Among his latest inventions is the "Dual-face cooling fan for a dynamoelectric machine." This innovative cooling fan is designed for use in alternating current generators. It features a ventilated housing that supports both a stator assembly and a rotor assembly. The fan includes a divider disk with multiple blades on each surface, which rotates with the rotor assembly. This design allows for the creation of separate air currents that are drawn axially into the housing for effective cooling. The divider disk prevents significant mixing of the air currents before they are expelled radially from the housing.
Another significant patent is the "Self oscillating vacuum actuator." This actuator is suitable for automatic belt tensioning systems and operates by oscillating automatically when connected to a constant vacuum source. This invention demonstrates Hallmann's commitment to improving mechanical systems through innovative solutions.
