“…The geometric structure and basic parameters (PM angle, PM residual induction, PM relative permeability, PM height, rotor yoke height) of permanent magnets that are present in the outer rotor BLDC motors affect the magnetic flux generated in the air gap. The change in magnetic flux generated for various parameters was analyzed by finite elements method by taking the geometric structure of the permanent magnets and the nonlinear characteristics into account [3].…”

E CS is a machine that provides recycling via separation of nonferrous metals by means of the eddy current effect. It separates copper, aluminum, brass, silver and similar valuable metals from wastes. The most important component of ECS that affects separation performance is magnetic drum. Higher rates of rotation and the multipolarity of the magnetic drum results in greater magnitudes of eddy currents in the metal that will be separated according to Faraday principles. In this case, the separation efficiency increases, while making the separation of smaller sized particles possible [1]. In General ECS, the drum is driven by a coupled motor. This motor rotates the drum directly by coupling or with a belt and pulley mechanism. In this case, reaching higher speeds is difficult due to loss in transfer organs and the balance effect. ECS machine and working principle scheme are given in Fig.1. This study proposes the design of an outer rotor BLDC motor to be installed in the drum to increase the ECS performance and to separate metals with small particle sizes. A BLDC motor consists of a stator with

The authors consider the possibilities to synthesise metamodels for the analysis and optimisation of brushless synchronous motors. The metamodels are presented for new designs of the outer-rotor permanent magnet synchronous motor and the outer-rotor reluctance motor. The metamodels are synthesised based on the results obtained by the numerical calculations of magnetic field taking into account magnetic saturation. Analysis of the results for the motor magnetic field and tests of the metamodels at the selected and intermediate points shows that these can be synthesised with acceptable accuracy using numerical calculations instead of expensive real experiments.
