Switched reluctance motor (SRM) and induction motor (IM) technologies are studied based on specific ASEAN Bangkok and Hanoi driving cycles. Range simulations and thermal analyses have been performed on standard driving cycles: ECE15 and WMTC Part 1 as well as ASEAN cycles: Bangkok driving cycle and Hanoi motorcycle driving cycles. The e-scooter ranges vary from 44 to 99 km depending on driving cycle, motor technology, and number of passengers. Finally, prototypes of both motors are manufactured and tested on a high-speed test bench. Some experimental results are reported in this paper. As a conclusion, despite differences in terms of performances, cost, and range, both drive systems are, however, suitable for electric scooter application.

In this paper, the implementation of a switched reluctance motor (SRM) and drive system for the propulsion system of a two-seat electric motorcycle is described. The overall design focuses on the required vehicle speed, acceleration, driving distance, and overall system cost, as well as reliability. The performance of the three-phase 6/4 pole (six-stator pole and four-rotor pole) and four-phase 8/6 pole (eight-stator pole and six-rotor pole) are investigated and compared by static performance analysis and dynamic performance analysis. Their performance is further investigated by finite element analysis. The indirect torque controller in a drive system for optimal torque and efficiency operation is also mentioned. A methodology for rotor position detection and its hardware implementation are also proposed. The designed 3.5 kW three-phase 6/4 pole SRM and its drive system were constructed and tested on the test bench. A maximum efficiency of about 82% could be achieved for the SRM and drive system. It was also installed on a 120-cc electric motorcycle, and the vehicle’s performance was also validated by on-road and dynamometer testing. The maximum vehicle speed reached was 82 km/h, and a cruising distance of about 98 km at a constant speed of 40 km/h was measured.
