Hi, In this article I will talk about the electric motor car. 

The design of the DC motor is the same as that of the DC generator. In an electric motor, the phenomenon of electromagnetic induction upon the interaction of the rotor winding current (anchor) with the main magnetic field causes the appearance of electromagnetic torque. Distinguish between DPS with independent excitation and dependent. DC motor power is from watts to thousands of kilowatts, efficiency is from 0.02-0.03 to 0.93. DC motors allow for a smooth and wide adjustment of the speed of rotation, resorting to a change in current in the rotor circuit by means of additional electrical resistance, to a change in the supply voltage, as well as to a change in the magnetic flux .
