Abstract: At present, interest in electric vehicles road reached a very high level. Undoubtedly, these
vehicles will be part of the main means of transport of the future but for them to dominate the market of
road vehicles, there is still much research efforts dedicated to this purpose. Also, new industries will be
created and will have trained many professionals in the fields of electric propulsion systems and
components of these systems. Rotary motors are the main components of electric propulsion systems of
road vehicles (scooters, cars, buses). There are several types of electric motors can be used in vehicle
propulsion systems: DC motors, synchronous motors with permanent magnets or electromagnetic
excitation, switched reluctance synchronous motors, squirrel cage induction motors. Performance of
these engines, with performance electric batteries or other energy storage mobile units, largely
conditions techno-economic performance of electric vehicles, which require careful consideration of their
choice. In this paper we present a comparative analysis of electric motors that are currently used in road
vehicle propulsion systems.
Electric vehicle was converted mainly from
the existence of an internal combustion vehicle
by replacing the internal combustion engine
and fuel tank with an electric drive motor and
a battery unit while retaining all other
components as shown in Figure 1.
Disadvantages such as heavy load, reduced
flexibility, and performance degradation
caused electric vehicle using this type of use
out of. In its place, modern electric vehicle is
deliberately built models based on the original
frame and body. This unique structure satisfies
the requirements of the electric vehicle and
makes use of a more flexible electric
propulsion.
A modern electric drive system is
conceptually illustrated in Figure 2. Drive
propulsion system consists of three major
subsystems: propulsion electric motor, power
supply, and auxiliary. Electric propulsion
subsystem consists of vehicle controller,
electronic power converter, electric motor,
manual transmission and driving wheels.
