    Abstract
    This paper deals with the optimal design of permanent magnet synchronous motors (PMSMs). Firstly, the general rules and principles of motor optimization are summarized, and a field-circuit coupled optimal design method is presented based on combined selection of variable parameters, objective functions and constraint conditions. Then, choosing multiple structural dimensions as variables, parametric analysis is made to research the influence of structural design parameters on performance of the PMSM. On this basis, an optimal design for a two-pole line-start PMSM is made, which can successfully reduce the dosage of permanent magnet and improve the performance-price ratio.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
