English: Diagram of revolving-field single phase generator with four poles. As the rotor turns, the lines of force at fours poles are cut by the coils inducing current. The output from four coils are "in phase".
The EMD SD75M and EMD SD75I are a series of similar diesel-electric locomotives produced by General Motors Electro-Motive Division between 1994 and 1996. The series is an improvement and extension to the EMD SD70 series, which further is an extension to the EMD SD60.

A direct start system as used on a marine slow-speed diesel is required to have up to 12 starts on a non-reversing engine or 6 starts on a reversible, or geared, engine. When starting the engine, compressed air is admitted to whichever cylinder has a piston just over top dead center , forcing it downward. [ 2 ]
All models have chassis and running gear, generator, traction motors and controls from GE, and Ingersoll Rand provided its 10 × 12 diesel engine. [6] The principle of operation was the same as modern locomotives, [ 7 ] the diesel engine driving a main generator of 600 volts DC with four axle-hung traction motors. [ 8 ]
Due to high cost of a generator, a set of sensors and limiters will trigger the alarm when the generator approaches the capability-set boundary and, if no action is taken by the operator, will disconnect the generator from the grid. [3] D-curve expands with cooling. The D-curve for a particular generator can be expanded by improved cooling.
The Cummins L-series engine is a straight-six diesel engine designed and produced by Cummins.It displaces 8.9 litres (543.1 cu in), and began production in 1982 as the L10 at the Jamestown Engine Plant in Jamestown, New York.
From 1940 through 1953, GE participated in a design, production, and marketing consortium for diesel-electric locomotives with the American Locomotive Company. In 1956 the GE Universal Series of diesel locomotives was founded for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium ...
