IEEE Transactions on Magnetics, 2013
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.

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 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 ...

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 ...

Design possibilities of multiple-pole cylindrical rotor synchronous machine excitation winding
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014This article provides design and finite element analyses information of two possibilities of cylindrical rotor synchronous machine excitation winding designs. It is focused especially on multiple-pole synchronous machines, where the presence of higher amount of machine poles reduces amount of available slots for excitation winding, therefore all ...

Excitation of the Automobile Alternator with the Claw Pole Rotor by Means of Stator Winding
SAE Technical Paper Series, 2000<div class="htmlview paragraph">It is known, that the alternator self-excitation is possible at capacitor loading [<span class="xref">1</span>]. From this follows, that the alternator excitation by means of capacitors connected to one or several stator windings, as from simple excitation winding is located on a rotor, is possible.</

2009 International Conference on Clean Electrical Power, 2009
In small ratings, direct-driven wind power applications multiple permanent magnet generators have become very attractive. Connected directly to the turbine axis, this type of electrical machine contributes to low price energy (the energy loss is diminished through the conversion, the turbine performance is increased) and to the reduction of the noise -
