Development of an Eddy Current Braking System for an e-Mobility Application

초록

This paper presents the design process of an Eddy Current Brake (ECB) system for an electric scooter application. In order to obtain sufficient braking force in the limited space of the electric scooter’s braking system, the impact of three key variables, air gap length, brake disc thickness, and magnet grade, are studied and analyzed by using three-dimensional (3D) finite element (FE) analysis. The braking torque of the ECB is also analyzed using FE analysis. Finally, an experimental setup is fabricated using a 1 kW brushless DC (BLDC) motor that was used in a commercial electric scooter, and preliminary results of measuring the rotational speed of the brake disc are presented.
