Linear hybrid excitation flux reversal machines are very attractive for low cost long stroke applications due to their simple and cheap secondary structure. This paper proposes a new hybrid excitation flux reversal machines with consequent-pole permanent-magnet arrays first. Owing to the adoption of consequent-pole permanent-magnet arrays, usage of permanentmagnet material of the proposed machine...
In this paper, a new linear wound-field flux reversal (LWFFR) machine for low-cost linear direct-drive applications is proposed. Similar to the conventional LWFFR machine, the proposed machine possesses the merit of a simple and compact long stator structure, a low cost, and a high flux adjustment ability. The novelty of the proposed machine is to be designed based on the magnetic gear effect. Hence,...
This paper proposes and analyzes a new three-phase primary-permanent magnet linear machine which is suitable for long stroke applications such as rail transits. The key of this new topology is to adopt modular secondary to improve machine performance and reduce machine size. The electromagnetic performances of the newly designed machine are analyzed, including the flux, back-EMF, inductance, fault...
