摘要
In the realm of electric motor design, achieving high efficiency at elevated operational speeds is paramount for various applications, ranging from automotive propulsion to industrial machinery. This research delves into the significance of high-efficiency interior permanent magnet synchronous motors (IPMSMs), particularly when operating in the flux-weakening (FW) region. The focus is on the pivotal role played by the characteristic current in expanding the high-efficiency region at these demanding operational speeds. By manipulating the characteristic current, this research explores avenues for improvements in efficiency during FW operation. The investigation is substantiated through a comprehensive approach, incorporating both simulation and experimental validation. Through rigorous analysis, the study demonstrates that manipulating characteristic current represents a viable strategy for improving the high-efficiency region of IPMSMs when operating at high speeds in the FW region.
