To solve the problem of large torque ripple interior permanent magnet synchronous motor (IPMSM), rotor surface notch design method was used for V-type IPMSM. In order to accurately obtain optimal parameter values improve performance motor, this paper takes output capacity and as optimization objectives, proposes a multi-objective layered based on hierarchical combined with Taguchi response (RSM...

In a multi-layer interior permanent magnet synchronous motor, the dand q-axis parameters vary nonlinearly according to different load conditions, consequently changing the level of saturation. The flux-linkage of dand q-axis conveys ripple characteristics resulting from mechanical structure and degree of magnetic saturation. If the calculated flux-linkage is correct, the torque using the Maxwel...

in this paper, a new field oriented control scheme with maximum torque for permanent magnet hysteresis synchronous (pmhs) motor has been presented. vector control method provides significant improvement to the dynamic performance of ac motors but in this method d- axis current is controlled such as the ratio of motor torque to motor current is a maximum, then the dynamic performance will be ver...
