An Innovative Dependable Reluctance Motor For High-Torque Low-Speed Applications

In the framework of a recent Italian National Research Project focused on drive-by-wire systems for industrial vehicles, a high-torque electric actuator was searched complying with stringent requirements in terms of specific performances, cost and dependability. This paper describes the considerations and guidelines that led to the development of an innovative electromagnetic structure for a double-anisotropic reluctance machine, illustrating its features and providing an overview of the theoretical, numerical and experimental results achieved.
