A ZQDR-410 traction motor (the large, dark component on the axle with small ventilation holes) A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains.
An Aveling and Porter traction engine-based railway locomotive, as used by Holborough Cement Co. Several traction engine builders (such as Aveling and Porter [37] and Fowler) built light railway locomotives based on their traction engines. In their crudest form these simply had flanged steel wheels to enable them to run on rails.
Electric drives manufacturer, including synchronous traction motors for electrical or diesel/electrical locomotives, multiple units, trams and working vehicle with main and auxiliary operating generators and their regulating systems. Ashwoods Electric Motors Manufacturer of Axial Flux and Interior Permanent Magnet Motors. LHP Motors
In a diesel–electric locomotive, the diesel engine drives either an electrical DC generator (generally, less than 3,000 hp (2,200 kW) net for traction), or an electrical AC alternator-rectifier (generally 3,000 hp net or more for traction), the output of which provides power to the traction motors that drive the locomotive. There is no ...
The traction motors may be powered directly or via rechargeable batteries, making the vehicle a type of hybrid electric vehicle. This method of transmission is sometimes termed electric transmission, as it is identical to petrol–electric transmission , which is used on vehicles powered by petrol engines, and to turbine–electric powertrain ...
Each DC bus powers two traction converters, with each traction inverter powering a separate traction motor. [ 45 ] [ 46 ] The locomotive uses four 1,300 kW (1,700 hp) MITRAC DR 3700 F [ note 1 ] fully suspended, bogie mounted traction drives to reduce unsprung mass .
During the initial development of railroad electrical propulsion, a number of drive systems were devised to couple the output of the traction motors to the wheels. Early locomotives often used jackshaft drives. In this arrangement, the traction motor is mounted within the body of the locomotive and drives the jackshaft through a set of gears ...
Keeping in tradition with GE's locomotive series nicknames beginning with the "Dash 7" of the 1970s, the C44-9W was dubbed the Dash 9 upon its debut in 1993. Part of GE's "Dash 9" series of locomotives, the Dash 9-44CW shares its frame, HiAd trucks, 16-cylinder 7FDL engine, and 752AH-31 traction motors with the GE Dash 9-40CW. But while the ...
