Inverter-Fed Asynchronous Motors for Traction Systems
IFAC Proceedings Volumes, 1977Publisher Summary Variable-frequency inverter-fed asynchronous motor constitutes, in the field of electric traction, an effective option to traditional d.c. motor. The success of this equipment is connected to the advantages the squirrel cage asynchronous motor may provide lower weight and small dimensions, higher power at high speed, less ...

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.
