Generator air path design

How is the atfspm generator prototyped?

Based on the design and considering the structural and magnetic limitations, the ATFSPM generator is prototyped according to the parameters that are presented in Table 1. This prototype is tested to validate the simulation results.

What is the difference between atfspm generator and conventional generator?

It can be observed that some parts of the conventional generator are saturated especially in the area that is exposed to the air gap, while in the ATFSPM generator, the magnetic flux density does not exceed the knee point of 1.64 T.

How can a generator set be simulated?

Generator sets must be properly installed to ensure that cooling air is not restricted or artificially heated by nearby heat sources or from recirculation. Fortunately, installation influences can be simulated using software called Computational Fluid Dynamics. CFD is a software tool used to predict fluid flow, including thermal influences.

How does a hybrid generator work?

A hybrid design procedure is presented based on analytical equations and finite element simulations. As shown in Figure 1, the proposed generator is a double-sided axial transverse flux machine. In each phase, one stator is sandwiched between two rotors. The disk shape of the generator results in two air-gaps with axial magnetic fluxes.

Can a flux-switching machine improve the performance of a direct-drive wind turbine generator?

In fact, by combining the features of a flux-switching machine into a transverse flux generator with an axial air gap, it is possible to improve the performance of a direct-drive wind turbine generator by overcoming traditional structures' challenges.

Can direct-drive permanent magnet synchronous generators be used in horizontal axis wind turbines?

According to the industry and academic resources, utilising direct-drive permanent magnet synchronous generators takes a special attention as the heart of horizontal axis wind turbines [3, 8, 9].
