Material selection software

The 2D model shown in fig. Maxwells equations are used to get the magnetic phenomena in the machine. Overall, the motor characteristics in 2D and 3D analyses are very similar, ignoring some differences such as the leakage flux occurred in end-windings and slot leakage reactance which depends on the winding shape in the slot. However, the copper loss in the coils and iron loss in the core are the main heat sources.

Flux passing through axial axis of the machine and current flowing through end winding must be considered in order to measure losses [3]. Generation of heat due to passing of current in winding coils having resistance R can be expressed by using joules heat loss equation:. Thus, heat generated is directly proportional to the square of current passing through the winding and resistance divergent increases with increase in temperature.

Calculation of Copper and Iron losses in the machine can be calculated by the 2D analysis. The results for the selected 35 grade neodymium magnet are shown here in table 5. Comparison of different graded magnetic material having different magnetic losses is shown in figure 7 which gives conclusion that our selected magnet will give the least loss full operation.

Flux density distribution is already displayed in fig. To calculate the losses more accurately current and voltage values [5] are displayed in fig. This paper gives the detailed study on material selection for the PMSM and gives its magnetostatic analysis for the different loss calculation. It is proposed that nylon type polymer material can be used for the small rated machine as it is having all required qualities and can eliminate the major iron losses. High graded rare earth magnetic material can be used to achieve high power density in machine.

This proposed model is under designing stage and further detailed study and improvement in material selection and magnets can be led to more and more efficient machine. The authors would like to acknowledge the project guide for providing their support and guidance for the ansys of the proposed model.

Material Selection As stated, earlier material selection is such type of process which will help to eliminate unnecessary losses resulting into increase in efficiency. Table 2 Properties of rare earth magnets Crystal structure of the neodymium magnet is composed of microcrystalline grains that are aligned in a powerful magnetic field during manufacture so their magnetic axes all point in the same direction.

Enhancements in CES Selector include: a quick and simple method to specify design objectives; a new Eco Audit Tool for eco design; new capabilities for cost analysis; further plastic selection options; and extended coverage of medical materials.

CES Selector combines comprehensive data on the properties of materials with powerful graphical software for analysis and selection. It enables designers, engineers and materials experts to explore materials and process options and to make and justify rational, auditable selection and substitution decisions. It also helps materials producers to analyse and position their products. The software is particularly valuable in balancing competing engineering, economic and environmental objectives.

The version makes it much easier to specify design objectives via a new pictorial menu in which engineers view and select the mechanical, thermal, electrical or barrier application that they wish to study. Simple drop-down lists enable them to choose variables such as dimensions, cost, strength or CO2 footprint to optimise or constrain. The software then plots graphs that show the best materials for the user's requirements and display trade-offs of competing objectives.

Although the CES Selector methodology is accepted as a standard for such rational materials selection, users previously had to specify design objectives as mathematical formulae. The new menu makes the software much quicker to use in practical design. This focus on practical use extends beyond software features — Granta is also introducing more flexible site- and company-wide licensing, as well as new training options for users.

Another new design feature is the Eco Audit Tool. A user enters information about a product design's composition, processing, use, transportation and disposal. The tool combines this with eco property data to estimate the energy usage and CO2 output at each stage in the proposed product's lifecycle.

Knowing which phases in the lifecycle will make the most significant contribution to environmental impact can help to guide the design strategy.
