Considering the fluctuating price of permanent magnet, magnetless machine is a new trend in development. Variable reluctance linear machines (VRLM) with simple structure, good robustness, and high dynamic performance, one potential candidates for direct-drive wave energy conversion (WEC) application replacing PM-excited machine. To ameliorate fault-tolerance performance VRLM, researchers have c...

In this paper, we present a semi-analytical model for determining the magnetic and electromagnetic characteristics of spoke-type permanent magnet (STPM) machine considering magnet segmentation and finite soft-material relative permeability. The proposed model is based on the resolution of the Laplace’s and Poisson’s equations in a Cartesian pseudo-coordinate system with respect to the relative ...

With the rapid development of microelectronic technology, wireless sensor nodes have been widely used in rotational equipment for health condition monitoring. However, many low-frequency applications, there still remains an open issue harvesting sufficient electrical energy to provide long-term service. Therefore, this paper enhanced variable reluctance harvester (EVREH) is proposed self-powere...

The Brushless Doubly Fed Reluctance Machine (BDFRM) is an emerging alternative for variable speed drive systems, providing a significant downsizing of the power electronics converter. This paper proposes new view on machine equations, allowing reuse standard control system design conventional synchronous and asynchronous machines: cascade with inner current control- outer loop. assumptions simp...

A multilevel modeling approach was developed for effective prediction for performance parameters of Switched Reluctance Machine. In this approach each system is described by its most efficient model. This paper addresses the problem of multilevel modeling applied to Switched Reluctance Machine (SRM). Using field analysis magnetic characteristics and inductance profile of the SRM are obtained. T...

The switched reluctance motors had gained more attention among the variable speed drives due to its inherent simplicity and low cost. It is an electronically commutated motor and need to be driven from a converter. The excitation of the different phases of the converter is dependent on the rotor position. This paper presents the simulation of the open loop control of a 6/4 switched reluctance m...
