Neodymium (Nd) magnets have been applied for a traction motor owing to its considerable maximum energy product. In addition, heavy rare earth elements such as Dysprosium (Dy) are added to the Nd magnets for withstanding severe conditions of a traction motor that includes high temperature and strong demagnetizing field. However, the employment of Dy causes critical issues regarding...

As a promising member of permanent-magnet brushless motors, flux-modulated permanent-magnet (FMPM) motors have aroused considerable attentions due to the outstanding low-speed large-torque characteristics. With the increasing demands of high quality PM motor, the high efficiency transmission in motor operation is one of the important performance evaluation indexes of motor. And then, the...

This paper presents the design of Electric outboard Permanent Magnet(PM) motor driven at a rated output and speed of 2.5 kW and 3,000 r/min, respectively, for use in small leisure boat. The PM motor for electric outboard motors is located below the water surface and it is necessary to set the proper PM operating point in consideration of the fact that the water cooling can be applied. In...

A permanent magnet synchronous machine (PMSM) has the advantages of simple structure, high power density and high efficiency, without the excitation winding and its loss. However, the magnetic field in PMSM is difficult to be regulated, due to its excitation by permanent magnet (PM), which leads to limited constant power speed range (CPSR) as a motor and/or confined voltage regulation capacity...

Flux-modulated permanent magnet (FMPM) motors have been considered as a promising candidate in the direct drive application due to the superior torque performance in the low speed condition. Yet, the output torque capability of the FMPM motor generally relies on the expensive rare earth permanent magnet (REPM), which is same to the conventional permanent magnet motor. It greatly limits the...

Comparative study of a 5kW novel modular multistage axial flux permanent magnet machine (MMAFPMM) is carried out. The mentioned MMAFPMM has three rotors and two stators. The rotors and stators are arranged in axial direction alternately and the two sets of windings are independent. So there are different forms to adopt the different operating conditions. They can work in respective,...

Traditional linear machines are under great influence of end effect because of their finite stacking lengths in transverse and longitudinal directions. Transverse end effect will produce a lot of flux leakage enclosed with air. Longitudinal end effect will cause imbalance of phase performance so that linear machine’s force fluctuation is aggravated. In this paper, a novel tubular switched...

The double-rotor hybrid excited axial switched-flux permanent magnet (PM) (DR-HASFPM) machine is a novel hybrid excited machine with single stator and double disk-type rotors. The double rotors have same structure without PMs and windings. The stator contains 6 doubly-H-shaped cores and 6 interlaced magnetized PMs. The PMs are sandwiched between the two doubly-H-shaped cores, where the...
