This paper presents a study on interior permanent magnet synchronous motors (IPMSM) design with different PM materials, ferrite and NdFeB magnet, for achieving high efficiency performance. The high efficiency performance for IPMSM is analyzed based on energy losses balance analysis between iron losses, copper loss and mechanical loss. In addition, the important machine characteristics are also analyzed...
This paper deals with the loss distribution of a three-phase induction motor (IM) and a BLDC motor considering operating point-of-core material based on the FEA and experiments. In order to increase motor efficiency, a high grade of core material can be used. However, sometimes it decreases or provides no improvement of efficiency. This is due to the fact that high-grade core materials generally have...
