The paper presents the design aspects of Inner Mounted Permanent Magnet (IPM) Synchronous Wind Generator. The design concepts and performance analyses have been done with traditional formula and finite element analysis (FEA) [1]-[5]. For electrical performance verification, no-load and full-load voltage, d- and q-axis reactance, voltage regulation ratio, demagnetizing condition, loss and efficiency,...
Magnetic transmission has the advantages of non-contact transmission, no friction, and noise or vibration weak. In 2001, D. Howe proposed a field modulated magnetic transmission, which has higher torque density and higher gear ratio than the conventional magnetic transmission[1]. Moreover, The existing transmission mainly focuses on single degree of freedom movement. In this paper, a novel high-performance...
The current trend in production EVs/HEVs is to use interior permanent magnet synchronous motors (IPMSM) as the means of providing power to the vehicle drive train. The efficiency of these machines can be extremely high (>95%) although this typically occurs in a relatively narrow range in the middle of the machine speed-torque curve. This is a concern for automotive applications as vehicles operate...
Variable-flux permanent-magnet machines (VFPM) are of great interest and many different machine topologies have been documented. This paper categorizes VFPM machine topologies with regard to the method of flux variation and further, in the case of hybrid excited machines with field coils, with regard to the location of the excitation sources. The different VFPM machines are reviewed and compared in...
This paper introduces a mechanically adjusted variable-flux (MVF) concept for switched flux permanent magnet (SFPM) machines. 2D FEA predictions and experimental results are presented showing the effectiveness of the MVF mechanism. Optimisation of the short circuit bar is carried out and several variations on the concept are presented, discussed, and experimentally validated.
With the developing of power system, there many power plant of HUBEI JINGZHOU CHINA with small generation capacity interconnected with weak lines and more and more small capacity interconnected to power grid threaten the stability of power system. The small capacity system is not normally meet local load, and sometimes even larger shortage. Aimed at the different types of HUBEI JINGZHOU CHINA small...
