Modeling of an Electric Axial Flux Motor Applied to Electric Vehicles

This paper presents the simulation of an electrical traction system using an Axial Flux Permanent Magnet (AFPM) motor using the MATLAB^® computational environment. It was developed the analytical model of the entire traction system which consists of a voltage inverter, a AFPM motor, a Field Oriented Control (FOC) control system with a torque reference and the dynamic system of the vehicle. For the simulation, it was considered two distinct scenarios,i.e. a horizontal plane with no inclination and an inclined plane in a way to allow the complete system dynamic comparison. The variables of interest are the electromagnetic torque, the currents in the machine’s terminals and the final vehicle speed, which proved the estimated dynamics.
