Abstract:

Permanent-magnet generators may be the most suitable choice for small co-generation systems due to a variety of merits. For instance, permanent-magnet generators are thermally optimised high-power density systems, which reduce the running costs by their performance and reliability. High-speed generators are currently being used in spindle drives, aircraft, power generation and electric vehicles. Distributed power generation has proven to be very effective and costs efficient in rural or remote areas as compared to building big power plants or long-distance transmission lines. The small distributed power co-generation unit using high speed permanent magnet generator is very efficient and cost-effective project. Moreover, high efficiencies i.e. over 90%, light-weight, low operating temperature, high insulation, no brushes/slip rings and almost negligible cogging torque make PMG’s ideal for distributed co-generation systems. In the past few years, most attention has been paid to “high speed brushless permanent magnet generators (HSBPMGs)”, for their many advantages i.e. substantial reduction in the size of the machine, higher efficiencies and power densities, etc. However, because of very high rotor speed and higher stator frequency, the design of HSBPMG is quite different from a conventional generator with low speed and low frequency. As speed increases, losses and temperature go up, so careful attention is needed while selecting the design parameters and material for the machine. This study aimed to use basic design process for high speed brushless permanent magnet generators, keeping the losses minimum by using appropriate material and cooling method. All the design parameters calculated analytically, finite element analysis (FEA) is carried by using Motor-Cad simulation software, results obtained are compared and verified, and a prototype modelling of the machine is presented.
