Title: | A new relieving-DC-saturation hybrid excitation vernier machine for HEV starter generator application | Authors: | Zhao, X Niu, S Zhang, X Fu, W |
Issue Date: | Aug-2020 | Source: | IEEE transactions on industrial electronics, Aug. 2020, v. 67, no. 8, 8835068, p. 6342-6353 | Abstract: | Benefiting from flexible flux control and short-circuit withstand ability, the hybrid excitation machine is an emerging starter generator solution for hybrid electric vehicle propulsion. However, to realize a brushless hybrid design in conventional permanent magnet machines, a three-dimensional magnetic circuit is usually adopted, leading to complicated mechanical structure and torque density sacrifice. To address this issue, a new relieving-dc-saturation hybrid excitation Vernier machine is proposed in this article, which integrates good torque density and bidirectional flux control within a simple and brushless structure. The key is to artificially construct reluctance effect in a consequent-pole Vernier permanent magnet machine (CP-VPMM) by introducing extra dc field excitation equipped with the relieving-dc-saturation ability. In this way, the advantages of bidirectional flux control in stator-dc-excited reluctance machine and good torque density in CP-VPMM are well combined in this topology, making it especially suitable for multimode starter generator application. In this article, the machine structure and its design mechanism are introduced, with its electromagnetic performance evaluated by the finite-element simulation. A prototype is manufactured and tested. Experiment results verify the feasibility of this new topology. | Keywords: | Brushless hybrid design Hybrid electric vehicle (HEV) starter generator Relieving-dc-saturation effect Vernier permanent magnet machine |
