Brushless dual-electrical-port, dual mechanical port machines based on the flux modulation principle

摘要

Based on the flux modulation principle, this paper proposes a novel brushless dual-electrical port dual mechanical port (DEDM) machine. From the view of derived torque equations, the proposed topology can be regarded as a combination of a motor/generator with a brushless magnetic continuously variable transmission. First, the structure and operation principle of the proposed machine are introduced. Then, the function and operation modes are discussed. Moreover, some parasitic effects which may influence the machine performance are also researched. Finally, several key performances are investigated and analyzed by finite element algorithm (FEA).
