DESIGN OF E-SCOOTER MOTOR WITH THERMAL ANALYSIS BASED ON DRIVING CYCLE

Abstract

This work investigates two different motor drive technologies, switched reluctance motor (SRM) and induction motor (IM). They are designed optimally to meet the desired performances for high speed electric scooters (e-scooter). Steady-state and transient thermal behaviors must be considered in order to study performance of motor cooling system. A common simplified lumped-parameter thermal model for SRM and IM are described. Finally, two driving cycles are simulated, a standard European urban driving cycle ECE15 and a more realistic cycle, Bangkok driving cycle. As a result, two motors can withstand rated torque condition. Their steady-state winding temperatures are well below insulation temperature limit. Their transient thermal behaviors are very satisfied on both standard driving cycles.
