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...
A dynamic model and simulation method of turbo-generator by reluctance network model is presented. The reluctance network model is based on the analogy between magnetic and electric circuits, and each tooth, yoke and slot of generator is expressed one of magnetic conductor cell, its main advantages are to take into the rotor movement and core saturation effects, with a good compromise between calculation...
