Traction electric motors are used to drive various equipment (electric trains, diesel locomotives, self-propelled cranes, trams and trolleybuses). The main differences between traction motors are related to the limited space in which they are located. The consequence of this was the specificity of the design (more compact dimensions, multifaceted frames, the presence of special devices for fastening, etc.). Electric motors for urban and railway transport must withstand significant operating loads, regardless of difficult weather conditions, as well as dusty and polluted air. Traction motors are designed to operate in a variety of modes (short-term, intermittent and intermittent with frequent starts). Current loads during vehicle propulsion can be 2 times higher than the rated ones. Since such electric motors are installed on passenger vehicles, they must meet safety requirements, in particular the requirements relating to explosion-proof electrical equipment.
