Line-start permanent-magnet motors can provide an alternative to the conventional single-phase induction motor in the fractional kW range. These motors employ a 2-pole magnet rotor and a simple skeleton stator construction with a bobbin coil for ease of manufacture. The motor can run synchronously in either direction and relies upon an impulse torque to start. The paper describes a combined circuit/finite-element approach that employs the power of the FE approach to accommodate the complex geometry and magnetic saturation and the simplicity of the circuit method for time-stepping transient solutions. This approach can be formulated in a manner that keeps computational solution times to a reasonable level, The analytical model is used to illustrate the run-up and steady-state performance of a commercial domestic pump motor with experimental measurements included to provide verification of the approach. The paper investigates the influence of certain key design features on the performance of the motor and in particular the direction of rotation.","PeriodicalId":177291,"journal":{"name":"IAS '96.

Omekanda, C. Broche, Michel Renglet","doi":"10.1109/IAS.1996.560166","DOIUrl":"https://doi.org/10.1109/IAS.1996.560166","url":null,"abstract":"This paper expands on a hybrid numerical method coupling the finite element method (FEM) and the boundary integral equation method (BIEM) developed to calculate magnetic fields in a switched reluctance motor (SRM). This hybrid approach is a solution to the issues stemming from the small size and odd shape of the SRM airgap, where meshing a FEM grid is difficult. In the past, the stator and rotor FEM domains kept their actual shapes, which resulted in problems with the definition of the unit outward normal vector n~ at the corner points of the SRM poles. So, the normal derivative of the magnetic vector potential, that is the tangential component of the flux density, was undefined at these points. In this paper, a new approach with new definitions of the stator and rotor FEM domains is presented. The new concept defines the SRM airgap as a ring in which circular boundaries permit the correct definition of the normal derivative quantities and exploits the natural Neumann condition. The electromagnetic parameters of a 7.5 kW SRM prototype machine were calculated using this new approach. They compare favorably with test data. Phase magnetization characteristics also have good precision and smoothness. These electromagnetic parameters were then used to assess and compare two different SRM models for the calculation of the torque on the motor shaft: the linear trapezoidal model; and the nonlinear model. The comparison between the measured torque and the torque as calculated with the two different models shows that the more simple trapezoidal model should be satisfactory in many cases, and could in particular be used in automated SRM designs.","PeriodicalId":177291,"journal":{"name":"IAS '96.

It is proved that the new modified boost topology has continuous input inductor current when it operates in the DICM. By using coupled inductor techniques, the input inductor current can be made ripple free when it operates in the DICM. It is proved that the new modified power converter can retain the \"voltage follower\" property with any coupling coefficient value. A comparison between the new modified boost power converter, the existing modified boost power converter, conventional boost, the Cuk and Sepic power converters used in power factor correction is presented. Several advantages are found in the two proposed boost topologies. The differences between the two proposed boost topologies are also presented.

Previous US Bureau of Mines (USBM) Pittsburgh Research Center research showed that, under static test conditions, electrical current levels permitted under present regulations may not limit cable temperatures to less than the 90/spl deg/C rating of reeled trailing cable. The USBM began a study of thermal characteristics of reeled trailing cable using dynamic test conditions more representative of field conditions where operators constantly reel in and pay out cable. This research is in support of efforts by industry associations and the Mine Safety and Health Administration to establish safety guidelines for cyclically rated reeled machines. The paper describes a unique approach to measuring temperatures within reeled cable under dynamic test conditions. Fiber-optic sensors embedded within the metallic conductors measure temperatures at 1-m intervals along the entire length of cable. Temperature measurements are reported to be accurate to within /spl plusmn/1/spl deg/C. The test setup requires access to only one end of the trailing cable, allowing researchers to freely reel in and pay out cable while temperature measurements are made, simulating field conditions. Manufacture of a fiber-optic-embedded trailing cable is described along with initial test results that indicate the fiber optic approach is viable.","PeriodicalId":177291,"journal":{"name":"IAS '96.
