In this paper a design and simulation model of a brushless, self-excited field winding machine is presented. The rotor of this machine possesses two windings, a field winding and a “transformer” winding, that are connected through a diode rectifier circuit. Using field-oriented control techniques, an AC magnetic field is generated by the stator windings that is always aligned with the transformer...
An accurate modeling method for electric parameters prediction of CSR (Contactless Slip Ring) is proposed in this paper. Parameters of CSR can be conveniently obtained before simulation and prototype design. In order to increase the accuracy of the predicted electric parameters, the main flux are corrected by taking the partially coupled flux into account, and the leakage inductance is obtained by...
