Through the analysis of the electromagnetic properties for the rotor coil of turbine generator, we obtained the main magnetic field variation characteristics for the rotor winding and put forward the short circuit fault between rotor inter-turns causing the potential difference and circulation between the parallel branches of generation stator winding spectral method was applied on the spectrum analysis...
The present work considers issues about optimization of the tooth zone of homopolar inductor generator with non-overlapping concentrated coils. The recommendations for the choice of optimal parameters of the tooth zone are made on the basis of the analysis of magnetic field in the machine's cross-section. The results of the experiment data of the inductor generator's test sample with the power of...
The reactive adjusting with working condition changing of novel dual-stator winding induction generator (DWIG) depends on the static excitation converter of control winding. A block chart of operational physical mechanism inside dual stator-winding induction generator is proposed, which depicts coordinate relation among physical quantities and reveals the operational mechanism to control the output...
A steady-state model with saturation is considered because all the experimental data have been obtained in steady-state tests. A model for the traction squirrel-cage induction motor containing the stator leakage reactance saturation, rotor leakage reactance saturation and magnetizing reactance is employed and a simulation is performed considering it.
A limited short circuit current PM motor is studied based on the segmentation of the rotor magnets. The principle is to reduce the magnetic flux by means of magnets subdivision and an increase of rotor pole number. The effect of magnet segmentation on machine characteristics is analyzed using finite element method (FEM). The short circuit current of designed fault tolerant machine is well limited...
In switched reluctance machine (SRM), the power density can be increased by using full pitched winding instead of concentrated winding. It is reported that full pitched segmented switched reluctance machine (SSRM) can give 40% higher torque than conventional SRM for the same frame size. In this paper, it is shown that SSRM can give approximately double the torque for the same frame size. This is because...
This paper focused on the research of new pattern ground power supply unit for start, and major in the doubly salient electro-magnetic motor (DSEM). Based on sufficient analysis of the doubly salient generator, this paper adopted multi-winding DSEM to get a new type of machine which matches the demand of aeronautic ground power system. This motor is simple, reliable and lower cost. And the experimental...
