A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or ...
A series DC motor connects the armature and field windings in series with a common D.C. power source. The motor speed varies as a non-linear function of load torque and armature current; current is common to both the stator and rotor yielding current squared (I^2) behavior [citation needed].

A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder) with an electrical polarity that depends on the direction of ...
In the USSR, per GOST 2582-72 with class N insulation, the maximum temperatures allowed for DC motors were 160 °C for the armature, 180 °C for the stator, and 105 °C for the collector. [13] The one-hour rating is typically about 10% higher than the continuous rating and is limited by the temperature rise in the motor.
There was therefore for a while a blue 6229 Duchess of Hamilton in the UK and a red 6220 Coronation in the US. R.A. Riddles drove for most of the tour, owing to the illness of the assigned driver. The locomotive (though not its carriages) was shipped back from the US in 1942 after the outbreak of the Second World War , and the identities of the ...
Another way is to use multi-system motive power that can operate under several different voltages and current types. In Europe, two-, three- and four-system locomotives for cross-frontier freight traffic are becoming a common sight (1.5 kV DC, 3 kV DC, 15 kV 16.7 Hz AC, 25 kV 50 Hz AC). [2]
