Abstract
Conventional electromagnetic speed-adjustable motor (ESAM) has wide application in speed adjustment. However, it is difficult to meet the high torque density and transient response requirement in occasion of transient output of high power. A new structure of dual-rotor electromagnetic coupling energy-storage motor (ECESM) is presented to output transient high power under low excitation power. Its mechanical structure and working principle based on eddy effect are explained and the transient equivalent circuit is derived. Finite element analysis (FEA) with Maxwell 2D is used to calculate electromagnetic performance and output characteristics (with terminal leakage considered). The results verify that the new ECESM has high performances in transient response and torque density, providing reference to the motor design and manufacturing.
