Applicability of Tractional Electric Motors

Russian Engineering Research, 2018
The practicality of three armature designs for tractional electric motors (power 560–755 kW, tractional force 5326 kgf) is analyzed. The use of an armature shaft of variable (reinforced) cross section in place of the armature with a sleeve is proposed, and suggestions are made regarding the assembly of the bearings.

Asynchrounous Motors in Electric Traction

EPE Journal, 2000
AbstractIn many applications the electric motors must possess a high overload capacity. That is particularly necessary in electric traction, in lifting gears and in various industrial applications.Initially either d.c. motors were employed with series excitation, able to assure high working flux value and to produce high torque, or d.c.
