In this paper a computationally efficient high-fidelity multi-physics design tool applicable to E-core power inductors is developed. The tool is composed of 2-D electromagnetic and 3-D thermal finite analyses coupled to models for inductor core and winding loss. The models are fully parametrically defined and appear as a black-box problem which can be used to perform parameter studies or design optimisation...
In this paper a design approach for a sensorless controlled, brushless, interior permanent magnet machine is attained. An initial study based on established electrical machine formulas provides the machine's basic geometrical sizing. The next design stage combines a particle swarm optimisation (PSO) search routine with a magneto-static finite element (FE) solver to provide a more in depth optimisation...
A methodology is proposed whereby performing a series of tests on a stator/winding subassembly can estimate the thermal envelope of a modular-wound single-layer machine topology. Concentrated windings offer many advantages, such as reduced manufacturing costs, improved thermal performance and readily lend themselves to fault-tolerant designs. Single-layer modular windings have inherent magnetic, thermal...
This paper presents a simple and computationally efficient approach for predicting iron loss within a field orientated controlled brushless AC permanent magnet machine which can cater for both rated flux and field weakened operation. The proposed method is readily incorporated as part of the design process and is based on two discrete time step 2D magnetostatic finite element field solutions describing...
