Review of Vibroacoustic Analysis Methods of Electric Vehicles Motors Open
The dynamic development of electromobility has resulted in new directions of research, one of which is the analysis of the noise of traction motors. The designs of the motors used in electric vehicles are relatively new and often modified.…
Design methods for limiting rotor losses in a fractional slot PMSM motor with high power density Open
Fractional slot PMSM motors enable high power density factors to be obtained provided that their electromagnetic circuit, appropriate mechanical structure and cooling system are properly designed, as well as when operating at a high freque…
Solid Rotor Core vs. Lamination Rotor Core in Fractional-Slot PMSM Motor with High Power Density Open
Fractional-slot PMSM motors allow for obtaining high values of power density factors, but at the same time, they are characterized by high values of rotor losses—in the rotor core and permanent magnets. The main causes of rotor losses in t…
Study on the Selection of the Number of Magnetic Poles and the Slot-Pole Combinations in Fractional Slot PMSM Motor with a High Power Density Open
Fractional slot, PMSM motors with a properly designed electromagnetic circuit allow for obtaining high power density factors (more than 4 kW per 1 kg of total motor weight). The selection of the number of magnetic poles to the specific dim…
Tests of Electrical Motor for Installation in the Wheel Hub of an Electric Car Open
The article presents the construction of test stand for testing an electric permanent magnet synchronous motor (PMSM) with an external rotor. The results of laboratory tests such as temperature rise tests for various motor parameters (such…
Alternate computational method for induction disk motor based on 2D FEM model of cylindrical motor Open
Disk motors are characterized by the axial direction of main magnetic flux and the variable length of the magnetic flux path along varying stator/rotor radii. This is why it is generally accepted that reliable electromagnetic calculations …
Numerical model for thermal calculation analysis of the wheel hub motor for electric car verified by laboratory tests Open
The article concerns the thermal analysis of an electric motor for mounting in a wheel hub of an electric car. The CFD model was calibrated on the basis of the results of laboratory tests of the prototype electric motor. The analysis was a…
Analysis of magnetic pull effect in disk induction motor with symmetrical/asymmetrical air-gap Open
Disk induction motor presents an interesting alternative to standard machine on account of its limited axial dimension. Its application may be contemplated for mine industry machines. However, in case of the design presented in this paper,…
The assumptions of the engine design for mounting in the hub of the vehicle Open
The article presents the concept of engine design for installation in the hub of an electric car wheel. The authors presented the advantages and disadvantages of direct drive and possible applications of this type. The publication presents…
