Comparative Study of Dual PM Vernier Machines
نویسندگان
چکیده
In this paper, two types of dual permanent magnet (PM) machines, i.e., stator slot dual-PM (SSDPM) machine and split-tooth (STDPM) machine, are investigated compared. Both machines have consequent pole structure with Halbach array PMs. Their difference lies in the position PM. The SSDPM has PMs slots, while STDPM between split teeth. Torque characteristics, average torques torque ripples, different slot/pole number combinations 24 slots/20 rotor slots/4 armature pair (24S20R4Pa) distributed windings slots/10 (12S20R4Pa) concentrated compared under both open-circuit on-load conditions. results show that is more competitive by delivering higher density power density.

This paper proposes a novel dual-consequent-pole Vernier memory machine (DCP-VMM) featuring alternatively arranged NdFeB and low coercive-force (LCF) magnet poles on the rotating and stationary sides, respectively. Due to the presence of LCF magnets that can be repetitively magnetized or demagnetized via a simple current pulse, the extra-high torque density at low-speed, and excellent high-effi...

The limiting velocity in open channels to prevent long-term sedimentation is predicted in this paper using a powerful soft computing technique known as Extreme Learning Machines (ELM). The ELM is a single Layer Feed-forward Neural Network (SLFNN) with a high level of training speed. The dimensionless parameter of limiting velocity which is known as the densimetric Froude number (Fr) is predicte...
