Prospects for the application of high-torque axial-flux electric motors for driving hydraulic systems of machinery
Abstract
The paper presents a feasibility study on replacing conventional internal combustion engines (ICE) used to drive hydraulic pumps in special-purpose vehicles with modern high-torque axial-flux electric motors featuring YASA topology. A comparative analysis of power characteristics and dimensional parameters of the two drive types is conducted. Using specific examples of municipal and road construction equipment (brush gear, dozer blades), it is shown that while maintaining the required operating power (18–50 kW), axial electric motors allow for a manifold reduction of occupied space, simplify machine layout, and enable power supply from traction batteries. The paper addresses the issues of comparative assessment of power parameters and overall dimensions of two types of drives, as well as illustrating the advantages of the new layout on typical components of special equipment. The authors conclude that it is possible to use electric motors to drive hydraulic systems of airfield, municipal, and road construction equipment, taking into account the derived comparison criteria.
