The purpose of this final work is to provide basic informations about electric motors that are an important segment in the functioning of various plants, industries, machines, devices, but also to show the application of electric motors on a real example, or on the example of cars. As the environment is being taken care of nowadays, the need for vehicles that pollute the environment as little as possible during their operation is growing. To this end, electric cars are being developed whose heart is actually the electric motor itself. In this work, special attention is given to the main division of the electric motors, respectively the division into DC motors and AC motors and their control that is related to starting electric motors and adjusting the speed. Also, the basic laws that are important to follow and that are important to know when working with electric motors are described. Knowledge of basic physical processes, knowledge of electrical engineering and mechanical engineering are also important. At the end of the work, a real example of the application of electric motors in cars is presented, more precisely in the new car "Nevera". That car uses electric motors with permanent magnets whose magnets are used to generate a constant magnetic flux. Also, certain performances that characterize that car are shown and described.
