Control strategies applied for reducing the vibration and torque ripple of a special Switched Reluctance Motor

The present work aims at the application of different optimization strategies in the electromagnetic analysis of the Variable Reluctance Motor (VRM) through Finite Element (FE) simulation. Two case studies are investigated: the first one aims to optimize the geometry and electrical characteristics of windings of a single-phase VRM 6/6, minimizing copper losses; the second aims to optimize a restricted set of geometric parameters of a 4phase VRM 8/6, maximizing the flux linkage in the phase coils per unit volume of magnetic core. In this way, by using the Finite Element Method (FEM), the results from the Differential Evolution (DE) and Particle Swarm Optimization (PSO) algorithms will be compared and highlighted. Then, the magnetic flux densities of the motors are analyzed before and after the optimization. The results obtained show good efficiency of the algorithms, since the objective functions were satisfied with respect to the reference models.

“…This implies that all winding resistive losses occur in the stator. Often the stator can be cooled more efficiently than the rotor, resulting in a smaller motor for a given power and size specification [2], [3].…”

“…In switched reluctance designs, "powerful radial force between the rotor and stator poles causes the vibration of the stator" (Takayama and Miki 2016). While research is progressing on design improvements to reduce noise levels, some level of this vibration is intrinsic to switched reluctance construction, and mitigation strategies carry tradeoffs of reduced efficiency (Correa et al 2011).…”

This report begins with a brief technical overview of motor technologies and some specific components and materials needed for their manufacture, followed by a supply chain analysis of emerging motor and drive technologies. The scope of this analysis includes electric motors for low to medium voltage (~1-1000 horsepower [hp]), industrial applications such as conveyors, extruders, pumps, compressors, blowers, refrigerators, and commercial heating, ventilation, and air-conditioning (HVAC). These stationary industrial and commercial electric motors account for 29% of total U.S. electrical energy use (Rao et al. 2021). Heavy industrial applications, including those from extractive industries (e.g., liquid natural gas pipeline compressors), are outside the scope of this report. Much of this review discusses the key resource inputs of these technologies.A key resource input refers to the most difficult-to-source component of a given motor. The focus on these key resource inputs informs which links in the supply chain are weakest. Note that sometimes key resource inputs are critical materials 1 or their derivatives, such as is the case of rare-earth permanent magnets, but in other cases, such as electrical steel, they are not. This report consists of two sections: a technical overview (Section 1) and a supply chain analysis (Section 2). There is some redundancy, to ensure that Section 2 does not require an exhaustive reading of Section 1.
