Research on energy saving and thermal management of high-efficiency and high-voltage motor based on fluid network decoupling

In order to solve the serious heating problem of high-efficiency high-voltage motor due to high power density and large electromagnetic load, this study carried out a fluid network to investigate the global fluid–solid coupling to predict temperature and analyze motor energy efficiency. Taking a 6 k...
