Permanent magnet assisted synchronous reluctance machine for drives of light vehicles

The environmental situation of many large agglomerations has deteriorated significantly recently. This forces responsible organizations to look for solutions, including local transport, that would be more environmentally friendly. Highly developed cities replace buses with combustion engines for those with electric drives, which eliminates harmful pollutants. The electrification trend is also followed by small, single-track vehicles. Increasingly, touring bikes and scooters are powered by electric motors supplied by batteries. The motivation for writing this article was the need to develop the technology of electric machines for drives of light vehicles. This paper presents and describes some types of electrical vehicles available on the market and their drives. This was the starting point for the development (Ansys Maxwell) of a new electric motor technology that could be applied to light vehicles. According to the imposed requirements, the motor should have the following parameters: torque – 0.49 Nm, maximum speed – 5151 rpm, power at least 270 W. Moreover, a process of motor's computer modelling with SolidWorks has also been used, leading to construction of motor's prototype. Comprehensive results of theoretical research and simulation are presented here. Furthermore, results of experiments obtained for the proposed motor have been shown and compared with all simulations.
