Fractional Slot Concentrated Windings: A New Method to Manage the Mutual Inductance between Phases in Three-Phase Electrical Machines and Multi-Star Electrical Machines
Mutual inductance is a phenomenon caused by the circulation of the magnetic flux in the core of an electrical machine. It is the result of the effect of the current flowing in one phase on the other phases. In conventional three-phase machines, such an effect has no influence on the electrical behaviour of the device. Although these machines are powered by power inverters, no problem should occ...
متن کاملModitication Factor for Sizing Equation of Electrical Machines-Single and Three Phase Induction Motors(RESEARCH NOTE)
Comparison between the results from the design procedure based upon the value of D2L (volume of iron) and IEC standard used by manufacturers indicates that the basic design equation of electrical machines must be modified by a proper modification factor. This modification factor is evaluated for single- and three-phase induction motors and its variation with motor rating and poles number is obt...

متن کاملCalculation of Slot Losses in High Frequency Electrical Machines
-As new magnetic materials as well as applications emerge in electromechanical conversion systems, one finds that electrical machines are increasingly moving away from the mainstream power frequency to much higher frequencies. This shift is mostly being driven by the fact that for the same power a higher speed machine is smaller in size. Operating at higher frequencies has its advantages on siz...
متن کاملReduced Basis Finite Element Modelling of Electrical Machines with Multi-Conductor Windings
Finite element analysis of electrical machines with multi-conductor windings can be computationally costly. This paper proposes a solution to this problem, using a reduced basis approach. The field-circuit problem is first solved in a single slot only, with a set of different boundary conditions. These pre-computed solutions are then used as shape functions to approximate the solution in all sl...
