Design of Permanent Magnet Synchronous Motor for Hybrid Sled-Type Forest Cableway

This paper proposes an interior permanent magnet (IPM) synchronous motor as solution for an electric sled-type forest cableway. Design evaluation based on 2D finite-element field analysis proves that the IPM motor meets the necessary specifications. The study approaches also the thermal and demagnetization analysis with the aim to determine whether the permanent magnets on the rotor disk are subject to overheating during typical electric motor operation, which could result in permanent-partial demagnetization of the magnets.
