The poles can be varied at a ratio of 1:2 and thus the speed can be varied at 2:1. [ 7 ] [ 8 ] [ 9 ] Normally, the electrical configuration of windings is varied from a delta connection (Δ) to a double star connection (YY) configuration in order to change the speed of the motor for constant torque applications, such as the hoists in cranes .

The Erie-Built used GE's model 746 traction motor, as used on the Great Northern Y-1 electric locomotive, [1] making it the first diesel-electric locomotive to deliver 500 hp (370 kW) per axle. [1] The locomotive was too heavy for a four-axle wheel arrangement, and had to be fitted with idler axles.
The ALCO RS-2 is a 1,500–1,600 horsepower (1,100–1,200 kW) B-B diesel-electric locomotive built by the American Locomotive Company (ALCO) from 1946 to 1950. ALCO introduced the model after World War II as an improvement on the ALCO RS-1. [2] Between 1946 and 1950, 377 examples of the RS-2 were built, primarily for American and Canadian ...
The Erie Lackawanna MU Cars were a fleet of electric multiple unit commuter railcars used by the Delaware, Lackawanna and Western Railroad (D&LW) and successor railroads in the state of New Jersey. The D&LW undertook electrification of its Morristown Line and related branches in 1929–1930, and purchased 141 motor cars from Pullman to operate it.
The U25B was announced by General Electric as a domestic model on April 26, 1960. It was the first locomotive powered by GE's highly successful FDL-16 engine. The U-Boat put GE on the road to becoming the top locomotive producer in the U.S., much to the chagrin of EMD .
The GE AC4400CW, , sometimes referred as "AC44CW", is a 4,400 horsepower (3,300 kW) diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. It is similar to the Dash 9-44CW , but uses AC traction motors instead of DC, with a separate inverter per motor.
