  • High frequency surge tester methods and apparatus
    Patent number: 5396179
    Abstract: A high frequency surge tester includes a high frequency detection circuit which is used to detect microfracture defects in the insulation of wire on wound coils. The high frequency detection circuit includes a high-pass filter which isolates an errant voltage response so that it can be integrated and compared to threshold limits to determine the magnitude of defects. The surge tester also detects shorts between coils and shorts between turns of the same coil.
    Type: Grant

  • Wire tensioner with program controlled bidirectional pulley wheel
    Patent number: 5310124
    Abstract: A wire tensioner maintains wire in a winding machine at a substantially constant tension during the process of winding coils for electrical components such as armatures. The tensioner has a pulley wheel that is driven by a bidirectional drive unit. During operation, the pulley wheel either feeds wire toward a workpiece or draws wire back, depending on the nature of the tension correction required.
