100kW 2400-4800rpm -spoke-PM bonded NdFeB traction motor preliminary design with FEM imported parameter circuit controlled dynamics validation

Abstract

The paper presents a solution for a super capacitor minibus (7 tons, loaded) propulsion system. The preliminary design is verified by key FEM validation. Critical operating points as short-circuit and overload up to 2p.u. are also investigated for PM demagnetization avoidance. In addition, field-oriented control (FOC) dynamics simulation results for a given speed-time actual urban travel between two subsequent stations, are also presented.
