A line-to-line short circuit fault of a stator is one of come faults in the real working process of single cage induction motors. Therefore, studying the electromagnetic field and electromagnetic force after faults is of great importance. In this paper, the transient mathematical theory model of the line-to-line faults of squirrel cage induction motors was presented, and the two dimensional field...
The loss of Switched Reluctance Motor (SRM) may cause the motor overheat. In many fields, the application of SRM needs a deeply research and analysis on heat radiating problem. To optimize SRM losses, a 2D transient model of three-phase 12/8 SRM is established with the finite element method following current chopping control principle. Through the Ansoft software analysis, the motor core flux density...
The paper presented a control scheme for parallel drive system of double Switched Reluctance machines. The sliding mode control algorithm is adopted in the main controller for closed-loop rotor speed control of main machine. The sliding mode control algorithm is also adopted in the subordinate controller for synchronized rotor speed and loads equilibrium distribution between main machine and subordinate...
The paper introduces the developed Switched Reluctance generator system made up of Switched eluctance generator, the power converter and the singlechip microprocessor digital controller. The excitation principles are given. The controller hardware and control strategy are also presented. The experimental tests of the developed prototype had been made on the established hardware platform. The prototype...
The paper introduces the components of the double switched reluctance motors drive system. There are two controllers, such as the main controller and the subroutine motor. The main controller is for the closed-loop rotor speed control of the main motor, in which sliding mode control algorithm is adopted. The subroutine controller is for the closed-loop rotor speed control of the subroutine motor,...
The comparison of the scheme in machine and power converter are made, such as 6/4 structure machine, 12/8 structure machine, 8/6 structure machine, 16/12 structure machine and the split supply power converter, the common switch power converter, the inductance commutation power converter, the resistance commutation power converter, the asymmetric bridge power converter, the bifilar winding power converter...
A new analytical nonlinear switched reluctance machine (SRM) model for rapid calculation is presented in this paper. It proves to be satisfactory both in accuracy and calculation speed. The model of SRM and its drive system (SRD) is then modularly developed as a sub-system library for airborne power system library based on Dymola/Modelica, a modeling software especially suitable for complex multi-disciplinary...
