Electric Motors for Light Traction
EPE Journal, 2004Modern electric motors for road electric vehicles (automobiles, scooters, bicycles), light rail transit (street cars, trolley lines, subway trains), guided transit systems and elevators have been discussed. The paper aims at various types of rotary brushless motors, direct electromechanical drives and practical solutions to light traction systems ...

IET Professional Development Course on Electric Traction Systems, 2008
Traction motors provide the motive force for the majority of railway vehicles. This paper looks at the fundamentals of the design and construction of the main DC and AC traction motor types that will usually be encountered in the UK and discusses some of the details that need to be considered.

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.

The Overhaul and Maintenance of Direct-Current Traction Motors
Journal of the Institution of Locomotive Engineers, 1955The paper is a review of the maintenance practices mainly developed by London Transport for 600-volt direct-current railway traction motors. The paper describes the procedures adopted to improve reliability and the methods used to carry out heavy repairs after failures have occurred.

Gear ratio and its effect on traction motors
Electrical Engineering, 1944The mechanical power delivered by the motors of electrically propelled vehicles is almost always transmitted through gears to axles. The few exceptions are some gearless electric locomotives designed many years ago. Although the top speeds of vehicles and locomotives have increased materially since the inception of electric drive, the very nature of ...
