THE INFLUENCE OF THYRISTOR CONTROL ON TRACTION MOTORS
IFAC Proceedings Volumes, 1977Publisher Summary Traction duty efforts free choice of speed and acceleration of a vehicle within certain limits. Allowing for gear and wheel-diameter, the tractive effort of the vehicle responds to the motor-torque and vehicle speed to motor speed.

Asynchrounous Motors in Electric Traction
EPE Journal, 2000AbstractIn 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.

9th IET Professional Development Course on Electric Traction Systems, 2006
This paper describes the use of electrical machines as the prime mover in railway locomotives and vehicles. First, the loading of traction machines is examined from knowledge of vehicle movement dynamics within the traction duty cycle. Then the operation of the principal types of traction machine - DC, synchronous and induction (asynchronous) motors ...

Progress in the design of traction motors
Electrical Engineering, 1949The past quarter of a century has witnessed important progress in traction-motor design. The primary objective of the designer has been to achieve weight reduction. In order to evaluate the advances made along this line, the author uses “speed-ratio power” as a basis of comparison.
