Substantiation of application prospects for direct-current motors with a windingless rotor in low-speed gearless electric drives.
A brief analysis of the impact of a gear box on the qualitative characteristics of an electric drive is presented. Practicable design measures intended to develop alternative gearless drives based on special low-speed d.c. motors with a windingless rotor (DCMWR) are described. Based on the analysis of the influence of the chosen values of electromagnetic parameters, engineering feasibility of low-speed DCMWR with a specified high efficiency value is shown. It is achieved by varying the current density of an armature winding.
