Back-Iron Extension Thermal Benefits for Electrical Machines With Concentrated Windings
IEEE transactions on industrial electronics (1982. Print), 2020 This paper proposes a novel, low-cost, effective way to improve the thermal performance of electrical machines by extending a part of the back-iron into the slot. This modification helps in reducing the thermal resistance path from the center of the slot
