“…Avrupa Bilim ve Teknoloji Dergisi e-ISSN: 2148-2683 108 The most important features of the motors to be used in electric vehicles are high torque at the time of first movement and low power consumption and efficiency at high speeds. Therefore, the motor drivers to be used for EVs must also be capable of providing these requirements (Lazari et al, 2014). While selecting the motor, it is necessary to know the max voltage, current and load values.…”

The production and use of electric vehicles (EVs) are becoming widespread. The negative effect of fossil fuel vehicles to environmental pollution also increases incentives and demand for electric vehicles. One of the most important equipment in electric vehicles is the electric motors. The characteristics of the electric motors (EMs), change according to the usage area and power of the electric vehicles. There are some structural changes to the electric motors used for small powerful electric vehicles and electric motors produced for medium and large powerful vehicles. Depending on the power and structure of electric motors, the characteristics of the drives that control these motors also change. In this study, the structure, types, operating characteristics of the small, medium and large powerful electric motors used in electric vehicles and the motor driver circuits required to running the motors are mentioned.

“…Therefore, motor drive requirements for EVs include high torque at low speed for fast starting, and high power at high speeds for cruising. For urban driving it is also necessary high efficiency in the low torque and low speed region [45]. Low rotor inertia and smooth torque are also valuable, since low inertia allows making the driving more comfortable, especially for direct drive motors, whereas a smooth torque reduces vibrations and wear in mechanical components [9].…”

Several factors including fossil fuels scarcity, prices volatility, greenhouse gas emissions or current pollution levels in metropolitan areas are forcing the development of greener transportation systems based on more efficient electric and hybrid vehicles. Most of the current hybrid electric vehicles use electric motors containing powerful rare-earth permanent magnets. However, both private companies and estates are aware of possible future shortages, price uncertainty and geographical concentration of some critical rare-earth elements needed to manufacture such magnets. Therefore, there is a growing interest in developing electric motors for vehicular propulsion systems without rare-earth permanent magnets. In this paper this problematic is addressed and the state-of-the-art of the electric motor technologies for vehicular propulsion systems is reviewed, where the features required, design considerations and restrictions are addressed.
