Investigating the use of grain-oriented electrical steel in axial-flux switched reluctance machines

Analysis and Simulation of Axial Flux Switched Reluctance Motor with Modified Stator Structure in Static and Dynamic Conditions

In this paper, a new structure of axial flux switched reluctance motors (AFSRMs) is proposed. Different combinations of rotors and stators affect motor torque and its performance. In this regard, changing the stator structure of the AFSRM leads to better results for torque and magnetic flux. The advantages of the proposed structure are short flux path, segmental rotor with improved flux density...

A Novel Approach to the Design of Axial-Flux Switched-Reluctance Motors

This paper presents the design of a new axial-flux switched-reluctance motor (AFSRM) topology for in-wheel drive vehicle applications. The features of the topology include a short flux path and an outer-rotor configuration. The proposed topology also uses a sintered-lamellar soft magnetic composite core material, and permits displacement of the rotor along the suspension axis, which reduces dam...

Secondary recrystallization characteristics of 3%Si grain-oriented electrical steel

A secondary recrystallization Lab study focusing on the secondary recrystallization temperature and magnetic properties was carried out on cold rolling industrial samples of 3%Si grain-oriented electrical steel produced by low slab reheating temperature technology. The results showed a secondary recrystallization temperature, determined by the observed grain size change, of 1080 C with annealin...

Characterization of Winding Faults in Axial Flux Reluctance

Nelson, Andrew Lincoln: Characterization of Winding Faults in Axial Flux Reluctance Motors in the Context of Electric Vehicle Propulsion Systems. (Under the direction of Dr. Mo-Yuen Chow.) Since the late 1980’s there has been a major resurgence in electric vehicle propulsion research and development. This trend has been stimulated by various factors, including rising fossil fuel costs, environm...
