Abstract
Electric vehicles are now a trend. Various types of electric vehicles have been produced. The development of electric vehicle propulsion motors is also continuously carried out to get the best performance. One type of electric motor that has a high efficiency is a brushless permanent magnet axial flux motor. This type of motor has a relatively large torque at low speeds. Therefore, this paper presents the results of testing the micro electric car propulsion system using a brushless permanent magnet axial flux motor with a modular system. Tests are carried out to obtain the value of torque, electric power, mechanical power, speed, and temperature rise of the motor. The driving motor is mounted on the rear axle of the micro electric car, then tested using a chassis dynamometer with disk brake loading. It tests with maximum torque of 37.8 Nm, at 550 rpm, with an electric power input of 1197 Watts. The highest efficiency is 76% obtained at 83rpm with 37,8Nm Torque. From the test results, the total efficiency of the drive system is considered low, it was due to mechanical losses on transmission and gear of the axle.
