The modal analysis plays an important role in analyzing the vibration and noise of the motors. The models of the stator which are based on the interior permanent magnet synchronous motors (IPMSM) by the 3D finite element software are analyzed. Firstly, it is significant to simplify the stator rind by considering the different components. Then the relationships of the different parameters of the stator...
Line-start permanent magnet synchronous motor with composite rotor is a new type of permanent magnet synchronous motor, which uses eddy currents induced in solid rotor and copper bars to achieve self- starting capability. In order to research the demagnetization of permanent magnets under three-phase short circuit and out-of-step fault, the finite element model considering saturation, eddy currents...
Modal analysis is an important step which studies the vibration characteristics of the motors. The passage analyzes the models of the stator by the 3D finite element software called Workbench, which are based on the interior permanent magnet (IPM) synchronous motor which has 6 pole- pairs and 36 slots structure. Meanwhile, the influence of the yoke thickness, tooth depth, tooth width, the stator coils,...
A combined analytical and FEM technique is proposed for predicting the air-gap magnetic field distribution of a PM embedded salient pole wind generator. The influence of slotting on both radial and circumferential components of air-gap flux density is taken into account. By employing the proposed combination technique, the magnetic field distributions when the stator and rotor are at different relative...
