From Conveyor Belts to Crushers: A Review on Radial and Axial Flux Induction Motor Advances and Applications in Industrial Mining Operations

This paper typically reviews the classification, design, and applications of induction motors (IMs), focusing on radial flux induction motors (RFIMs) and axial flux induction motors (AFIMs), particularly in the mining sector. RFIMs, known for their robustness and cost-effectiveness, are preferred for equipment such as conveyors, pumps, and ventilation systems. Recent advancements include enhanced topologies and techniques to improve performance and reliability. AFIMs, with their compact design and high torque capabilities, offer advantages in space-constrained applications. Innovations like multi-stator/multi-rotor configurations and optimized control strategies enable these motors to excel in harsh environments. The document also addresses inrush current mitigation techniques, including adjustable frequency drives, for harsh mining environments. Emphasizing durability, reliability, and energy efficiency, these developments ensure that induction motors meet the rigorous demands of industrial and mining environments.
