Abstract

The paper presents the study of two permanent magnet synchronous machines, with outer rotor, dedicated for electric scooter applications. The electrical machines will be analyzed in order to assure the most suited scooter propulsion. The variety of topology is basically obtained through specific winding configuration and poles/slots ratio. The design results are validated numerically through finite element method. A skewed topology proves the reduction of torque ripples. Also, in order to improve the energetic performances of the studied machines, a unity power-factor control strategy is employed.
