Considering that each the armature and subject present reverse concurrently, the conduct of the motor is similar to that when energized with immediate existing. To achieve better traction motors manufacturing running circumstances, AC railways are often supplied with present-day at a decreased frequency compared to industrial offer useful for standard lighting and ability; Particular traction current energy stations are used, or rotary converters utilized to transform 50 or sixty Hz commercial electric power for the 25 Hz or sixteen+2⁄three Hz frequency utilized for AC traction motors.
Trains to start with entered service in South The usa, Africa, and Asia by way of construction by imperial powers, which starting while in the 1840s designed railroads to solidify control of their colonies and transport cargo for export.
