Parameter Measurement of PM Motor in dq Equivalent Circuit.

modeling and simulation of stator winding faults in squirrel cage induction motor via magnetic equivalent circuit method

induction motor especially the squirrel cage type of this motor plays important role in industry. according to the application type, this motor place against various stresses that are caused failure in the motor. the most common failure is related to the stator winding. among these failures are turn-to-turn, coil-to-coil and phase to phase faults. flow the high current do to the induction resul...

Effective Measurement of DQ/IQ for BI

DQ/IQ measurement in general and in the specific context of BI has always been a topic of high interest for researchers. The topic of Data Quality (DQ) in the field of Information Management has been well researched, published, and studied. Despite such research advances, there has been very little understanding either from a theoretical or from a practical perspective of DQ/IQ measurement for ...

Finite Element Method Simulation and Comparison of a Segmented-PM Motor and a Whole-PM motor

A permanent magnet synchronous motor (PMSM) with rotor embedded segmented permanent magnet was analyzed. The structural features and flux weakening principle are introduced. The shape of the rotor is optimized to get a sinusoidal air gap magnetic density waveform and reduce the toque ripple. The whole-permanent-magnet (PM) motor and the segmented-permanent-magnet motor are compared from the asp...

Rf Equivalent-circuit Model of Interconnect Bends Based on S-parameter Measurements

A modified model for RF interconnect bends on lossy substrate in CMOS technology is presented. The model parameters are extracted directly from the on-wafer S-parameter measurements. The accuracy is verified up to 20 GHz by the measurements of the test structures. © 2005 Wiley Periodicals, Inc. Microwave Opt Technol Lett 45: 170–173, 2005; Published online in Wiley InterScience (www.interscienc...
