About DELTATRONIC
DELTATRONIC Technology GmbH, based in Dornbirn, Austria, specializes in testing and measurement technology for electric motors and power supply systems. The company develops and manufactures Rotor Quality Analyzers for quality inspection of squirrel-cage rotors in the laboratory as well as for in-line quality assurance in mass production lines for electric motors and hermetic compressors. The testing systems use inductive measurement and resistance measurement and detect defects such as broken bars, porosity, solder joints, bar angle deviations and eccentricity; with a cycle time of approx. 6 seconds per rotor, 100% inspection of production batches is possible. In addition to rotor testing devices, DELTATRONIC manufactures insulation testing devices (Oiltester) for liquid insulating materials and insulating films, which are used worldwide for commissioning and maintenance of oil-insulated systems. The expertise was developed in close collaboration with leading manufacturers of electric motors and major power utilities; customers on all continents use the testing technology. The service offering includes calibration (recommended interval: 2 years), repair and spare parts.
