Stator/Rotor Pole Combinations and Winding Configurations of Variable Flux Reluctance Machines
IEEE Transactions on Industry Applications, 2014In this paper, stator/rotor pole combinations, winding configurations, and electromagnetic performance of novel variable flux reluctance machines (VFRMs), which employ a doubly salient structure similar to switched reluctance machines (SRMs) but with stator-located dc field windings, are investigated. VFRMs with 12 stator poles are taken as examples to

A two-pole induction machine with flexible rotor shaft and whirling rotor motion is considered. A 30 kW test machine is built with four-pole damper winding in stator. The construction of the machine and the test-setup are presented. The amplitude of measured vibration oscillates at twice the slip frequency.

Consequent-Pole Toroidal-Winding Outer-Rotor Vernier Permanent-Magnet Machines
IEEE Transactions on Industry Applications, 2015A novel consequent-pole toroidal-winding outer-rotor (CPTW) Vernier permanent-magnet (VPM) machine is proposed in this paper. Different from a regular VPM machine, the stator and rotor of the proposed machine employ the consequent-pole and toroidal-winding configurations, which can significantly reduce magnet consumption, shorten the end-winding length,

A Parallel Hybrid Excited Machine Using Consequent Pole Rotor and AC Field Winding
IEEE Transactions on Magnetics, 2019Hybrid excited (HE) machines with both permanent magnet (PM) and field winding excitations, inherit the benefits of PM machines and improve the flux regulation capability. This paper proposes a novel consequent pole HE (CPHE) machine. The PM pole pair and the iron pole are alternately placed on the rotor, while both the armature winding and ac field ...

Design of Vernier Motor with Modular Winding Using Rotor Pole Pair Determination Method
2018 XIII International Conference on Electrical Machines (ICEM), 2018In this paper, a method for deriving the rotor pole pair number of modular winding applied vernier motor is proposed. Unlike conventional permanent magnet synchronous motors, the pole-slot configuration of the vernier motor is determined by a fundamental vernier principle that is composed of the rotor pole pair, stator slot and stator winding pole pair

A two-pole induction motor has been fitted with an extra three-phase four-pole stator winding to damp the unbalanced magnetic pull caused by eccentricity. In traditional two-pole induction machines, the interaction of two- and four-pole flux produces most of the magnetic forces.

IEEE Transactions on Energy Conversion, 2010
A simple analytical method is developed to compare the combinations of stator and rotor pole numbers in flux-switching permanent magnet (PM) machines in terms of back electromotive force (EMF) and electromagnetic torque. The winding connections and winding factors of machines having all poles and alternate poles wound, and different numbers of phases ...

A Novel Fractional Slot Non-Overlapping Winding Hybrid Excited Machine With Consequent-Pole PM Rotor
IEEE Transactions on Energy Conversion, 2020A novel fractional slot non-overlapping winding (FSNW) hybrid excited (HE) machine with consequent-pole permanent magnet (PM) rotor is proposed in this article. The abundant harmonics in the stator magnetomotive force (MMF) of FSNW, which are harmful and tend to cause parasitic effects in conventional PM machines, are utilized to regulate the magnetic ...
