The free piston energy converter (FPEC) is a new type of power unit for hybrid electric vehicle. In a FPEC, an internal combustion engine driven permanent magnet linear generator (PMLG) may be utilized to produce electrical energy. This paper discusses the issues that are pertinent to the design of a linear permanent magnet generator for application in a FPEC. To achieve the required high power density...
In order to improve the wind energy utilization factor of wind-power generation system, a new type of Permanent Magnet Synchronous Generator(PMSG) with Opposite-rotation Dual Rotors(ODR) has been proposed in this paper, mechanical structure and operation mechanism have been discussed. Magnetic field has been analyzed by FEM and circuit method. Magnetic flux, flux density and EMF are calculated to...
In order to improve operation performance of underwater vehicle anti-rotation propulsion system, a novel PMSM with Anti-rotation Dual rotor is proposed. It can be substantially simplify system structure, decrease volume and cost, moreover, improve reliability without brush and slip-ring. After the principles of operation, structure, and features are discussed, Design methodology is given. Both the...
