Design and performance of the field regulated reluctance machine

Power Electronic Drives, Controls, and Electric Generators for Large Wind Turbines–An Overview

“…The BLDC multi-phase reluctance machine (MRM; BLDC-MRM), originally proposed in [69][70][71], consists of a multiphase single-layer winding with diametrical coils, a uniformly slotted laminated stator, and a rotor with a large magnetic reluctance in the q-axis between the poles (Figure 17 the stator, designs with 5, 6, 7, and 9 phases are possible, and for the rotor, radially laminated constructions with multiple flux barriers or axially laminated anisotropic topologies can be employed. In a BLDC-MRM generator, the stator and the rotor have the same number of poles.…”

Proposal with 2D FEM analysis of a six phase, 12 poles, 3kW, 200 rpm BLDC multiphase reluctance machine wind generator

“…The BLDC-MRM term and equivalence principle ( Fig.1.a,b,c) was presented in [10]. Extended studies of the BLDC-MRM begun 20 years ago and can be found in [11] (parallel connection of phases) and [12] (series connection of phase). The emergence on the market of high energy PMs has put these projects on hold, until now, when the price of high energy PMs is too high for most of applications.…”

BLDC multiphase reluctance machines for wide range applications: A revival attempt

“…The same rationale is valid for SRM drives. In the hunt for higher torque density without PMs, references [4][5][6] have investigated the BLDC multiphase reluctance machine (BLDC -MRM) principle with promising preliminary results. But the spectacular advance of PMSMs had led its practical abandoning twenty years ago.…”
