The Brushless Doubly Fed Reluctance Machine (BDFRM) is a type variable speed machine with two sets of windings. One set is fed from a variable frequency inverter while the second set is fed at constant frequency. Comparing with the traditional induction machine, BDFRM has simple structure and higher efficiency, higher power density, smaller size and lower maintenance cost. So, it is important to build...
In this article, we present a novel gang control system in drive application for a six-phase induction motor, forcing on the properties of gang Variable Voltage Variable Frequency(VVVF) control system, which is based on integration of power drive modules and power electronic system. The design of VVVF system for six-phase induction motor is set up, the results of theoretical analysis and MATLAB simulation...
The new-style dual stator-winding induction generator (DWIG) is presented in the field of wind power supply. The performances of the system operating with 1:2.5 speed range with wind power supply under no-load and rating-load are simulated. The designs of excited winding circuit are presented. The results show the good voltage performances and the large output power can be controlled.
In today's electrical drives, the use of more than three-phases to implement the electrical machine stator winding is a frequently adopted provision to enhance system power rating and fault tolerance. In VSI-fed electrical machines, multi-phase windings are adopted in both their symmetrical structures (with n equally distributed phases, supplied by a single n-phase inverter) and in their multiple...
