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.

Verification of insulation tests for traction motors

Electrical Engineering in Japan, 1997
More than 30,000 thousand dc motors are used by the Japan Railway group companies alone as traction motors for railway vehicles. Insulation breakdown of armatures is one of the most important problems in traction motors. Therefore, various insulation tests are carried out for each motor in overhaul. The methods for insulation tests were determined more
