针对传统永磁同步电机（PMSM）弱磁运行的不足，提出了一种随转子转速自动弱磁的新方法。介绍了永磁同步电机（PMSM）的弱磁原理。研究了弱磁速度范围，并详细分析了用于调节转子漏磁阻的磁导体上的受力。给出了有限元现场仿真分析结果，验证了该方法的有效性和可行性。
As traditional permanent magnet synchronous machines (PMSM) are deficient in flux weakening operation, a new method of automatic flux weakening with the rotor speed is presented. The flux weakening principle of permanent magnet synchronous motor (PMSM) is introduced. The flux weakening speed range is investigated and the forces on magnetic conductor which for adjusting the leakage reluctance of the rotor are analyzed in detail. Results from the finite element field emulation analysis are presented to verify the validity and feasibility.
