  • Measurement of stator core magnetic characteristics

    A quick and simple test method for measuring the B-H curve and power loss in generator stators, both as loose laminations and finished core packs, has been developed. This provides a greater level of understanding about the characteristics of stator cores at various stages of the manufacturing process in order to prevent finished generators from being out of specification. The capabilities of the measurement rig have been explored both theoretically and experimentally. Experiments have been carried out on-site on industrially manufactured synchronous generators and permeability and power loss in a batch sample of stators have been measured. Considerable degradation in the steel's magnetic properties has been found. Mean permeability at 1 T decreased by 23% after compression and welding. For specific power loss, the welding process caused an increase of 5% in the mean value and an increase of 36% in the standard deviation. The results allow conclusions to be drawn regarding manufacturing effects, variability and generator performance.

  • Field correlation between electromagnetic and high flux stator core tests

    In stator core interlamination insulation fault tests, there is a commonplace expectation that the Quad signal detected by EL CID is correlated to the high flux test, at the rate of 5-10°C/100 mA. Evidence to date has been supportive but inconclusive. A new opportunity has been taken to review 106 reported core fault test results from the field on turbo and hydro-generators, where both tests were conducted on the same fault. A number of normalisation corrections were proposed and applied, which resulted in the population mean trend correlation lying between 8.5-10.7°C/100 mA with a 95% confidence factor. The central quartiles embrace the 6-12°C/100 mA range, close to the expected rate.

  • Estimation of Suppressed Iron Loss by Stress-Relief Annealing in an Actual Induction Motor Stator Core by Using the Excitation Inner Core Method

    It is well known that magnetic properties, such as iron loss of a stator core in a rotating machine like an induction motor, are strongly influenced by residual stress caused by manufacturing processes. In particular, both the residual stress that was generated by the punching and the laminating process greatly influence the iron loss. However, it is not easy to evaluate the magnetic properties of a complex shape like the actual stator core. We are proposing the excitation inner core method to evaluate the change in the magnetic properties of the actual stator core. This method can easily evaluate changes in magnetic properties in an actual stator core. We applied this method to a comparison of the magnetic properties before and after annealing the stator core, which was annealed by the low-frequency induction heating method. In this annealing, the center section of a tooth in the stator core was heated for eight minutes at temperatures up to about 800°, and afterward the stator core was slowly cooled to room temperature. Iron loss of the stator core before annealing decreased by 4.9% (Bex=1.5 T) after annealing.

  • Research on PMSM of spliced stator core

    This paper proposes a spliced stator core structure motor permanent magnet synchronous motor analysis method, and compares the spliced structure SPM with the conventional integrated structure SPM, analyzes the influence of electromagnetic performance, temperature rise, structure and so on.

  • Research on Configuration of Stator Core Stacks in Magnetic Bearing

    The performance of magnetic bearing is determined the characteristics of magnetic materials, which is affected on the configuration of stator core stacks because of different stress under manufacturing process. The experimental results are shown that stator core stacks with reeling condition will lead to large current ripple in magnetic bearing's coils, and then the power loss will be increased dramatically. The improved stator core stacks configuration is designed, that is to say, the stator core stacks is manufacturing with lamination condition. It can effectively reduce current ripple in magnetic bearing's coils and the power loss of magnetic bearings because of its little stress. Then, the magnetic characteristics of two types of stator core stacks in magnetic bearing have been measured using magnetic materials measurement equipment to verify the correctness of the design.

  • Reduction of Stator Core Loss in Interior PM Machines for Electric Vehicle Applications

    Stator core loss of four interior permanent magnet (IPM) machines is studied for electric vehicle applications in this paper. The no-load air-gap density, core loss density, core loss harmonics, and the segregation of hysteresis and eddy current losses are investigated with finite-element analysis. The results show that the rotor surface shaping of a single-layered IPM machine and increasing the rotor magnet layers can reduce the stator core loss due to the harmonics of the rotor magnetomotive force. The stator core loss reduction effectiveness of rotor surface shaping is similar to a two-layered magnet configuration, but the reduction effectiveness is less than that the magnet layers increased to three numbers. An IPM machine with three-layered magnets rotor is prototyped to verify the analysis.

  • Calorimetric measurement of stator core losses

    Calorimetric method is an accurate method for loss measurement and has been used quite often to measure the losses of an electrical machine. However, segregating the measured losses to stator and rotor losses is impossible with the conventional calorimetric method. This study suggests a modified calorimetric method to measure the no-load stator core losses. The proposed calorimeter is constructed and the uncertainty regarding the measurement is also analyzed. Finally, the measured losses are compared with the FE simulated result.

  • Investigation on structure of stator core and winding for high speed PM machines

    The high speed permanent magnet (PM) machine has been widely investigated since it has small size, high efficiency and power density. However, due to the high rotor speed and high frequency of the stator flux variation, the design of a high speed machine is quite different from designing a conventional machine. This paper will pay attention to the design of stator core and stator winding for a high speed PM machine. A comparative study on the influence of different stator structures on machine performance for a same PM rotor is carried out based on the magnetic field analysis

  • Eddy current loss analysis of stator core through bolt of hydrogenerator

    In some of rotating machines such as hydrogenerators, through bolts may be used to fix the laminated iron core. In such bolts which are incorporated in the alternating field, eddy currents may be induced and this can lead to loss increase and overheating. In this paper, eddy current analyses of stator core through bolt are performed and some investigation on 3D effect and magnetic saturation are presented.

  • An advanced technique for detecting inter-laminar stator core faults in large electric machines

    An advanced technique for detecting incipient inter-laminar insulation failure in stator cores of large electric machines is proposed in this paper. The proposed scheme is an offline method based on low flux stator core excitation that employs a new probe. An iron-core probe is placed in the wedge depression area of the stator and scanned axially to detect the variation in the measured flux due to a fault. Two fault indicators that provide clear indication on fault severity and location are proposed in this paper. A 120-MW ac machine stator was tested under a number of intentionally inserted fault conditions using portable field equipment recently developed. The experimental results show that the fault existence, location, and severity can be determined reliably using the proposed scheme. It is also shown that the fault detection sensitivity and reliability, inspection speed, and user convenience are significantly enhanced.
