The design of magnetic component assemblies that must withstand a variety of environments and then function correctly is dependent on the appropriate use of encapsulating formulations. Specially developed material processing parameters are often critical in the encapsulation process and enable us to provide high reliability magnetic components. This paper discusses encapsulation process parameters for several of our formulations utilized for magnetic components. Process deviations that affect component functionality are also discussed.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

Static excitation resistant rotor insulation for turbine generators 涡轮发电机转子抗静励磁绝缘

Testing and service performance of electric motor insulation shows electrical life is adversely affected when solid state drive systems are applied. Therefore, there is a concern about the electrical life of generator rotor insulation when driven by static excitation systems, especially with high ceiling excitation systems. The high ceiling static excitation systems for turbine generators produce an output voltage with a large AC or pulse component at a designed repetition rate of typically 360 Hz. Since rotor insulation has not typically been exposed to AC voltage, the AC electrical life of the rotor insulation was not a technical issue and little was known about its affects on service life. Since static excitation has become popular, a program was developed to investigate the AC electrical life of rotor insulation. This paper defines static excitation voltage applied to generator rotor insulation and discusses its effects on service life through laboratory testing. Critical rotor insulation materials, like the turn to turn insulation and the slot cell insulation, are discussed for both air-cooled and hydrogen-cooled rotor designs.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

The MFHS consists of a heavy base with two poles mounted on it that support a slip ring and housing. Wires for the DC motors of the system and a potentiometer pass through the center of one of the poles to the slip ring, where its brush assembly and conduction rings connect to the motor wires. The DC motors are mounted on either end of a pivoting pole. Attached to the motors are propellers. When the motors change speed, the torque generated by the propellers moves the position of the pivot arm. A potentiometer monitors the position of the pivoting arm and is used as a feedback signal. This system behaves similar to a double integrator system with poles very close to the j/spl omega/-axis. Close to instability behavior of this system creates a challenging problem for design of a control system. As a first controller design, a PID controller was designed and implemented for this system using XPC/Simulink in MATLAB, which is a real time prototyping platform software.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

This need is even more evident in microjoining (small scale resistance welding) due to the number of process variables. This paper outlines an application in which statistical methods are applied to a microjoining process. The paper documents the methodology used to establish optimized process parameters for in microjoining of an electrical lead frame design. The methodology includes utilizing experimental design to develop a linear mathematical model of the process. A preliminary (screening) as well as final design of experiment is performed using a HF inverter and capacitive discharge welding equipment. The validity of the model and its linear assumption are evaluated and a transformation is performed to ensure linearity. Once the regression model has been verified, an optimization is performed to maximize the response variable and determine the optimum process parameters.","PeriodicalId":228071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

It helps to increase the insulation strength. \"Life term\" of the bars with the full field reduction was higher than for similar bars with a partial reduction.
