This paper aimed to find out a model of 1 kWp flat-quasi linear permanent magnet generator (LPMG) for ocean wave power plant in South Java Ocean. First, a flat-quasi LPMG is modeled based on the wave characteristic at the placement site. The model was then simulated using finite element software of FEMM 4.2. Next, the model was optimized to find out the optimum output power and cogging force. The...
This paper focuses its attention on the wave energy converters (WEC), particularly the ones that use a moving body (wave activated bodies) coupled directly to a power take-off (PTO). It describes the analysis and the design of a small reciprocating linear permanent magnet generator. A comprehensive design methodology, which embraces both the electromagnetic and mechanical design, is described. Nonlinear...
This paper describes design aspects of low cost electrical machines used for highly integrated 48V starter-generator systems. It is shown that a belt-driven interior ferrite magnet machine with integrated power electronics and controller is a good solution for micro and mild hybridization approach. Considering the given automotive constraints and requirements, a machine design optimisation process...
Low cost and low cogging torque are the most important aspects in the design of direct drive PM wind generators. In this paper a low cost PM wind generator with an irregular, parallel slotted stator is analysed with respect to cogging torque. The sensitivity of average torque and cogging torque to machine dimension variations are investigated. From this a method is proposed whereby regions of low...
