The new model MP15DC designation thus meant Multi-Purpose locomotive, 1500 hp, DC generator. Originally the locomotive was simply designated the MP15; the arrival of the alternator/rectifier MP15AC in 1975 changed the name. With the success of the MP15, there was a demand for a model with an advanced AC drive system.
The "S" designation originally stood for six hundred horsepower and the "N" designation for nine hundred horsepower, although they were used for the more general designation of smaller and larger engine models after the more powerful 567 model engines replaced the Winton engines. The "C" designation stood for cast frame locomotives and the "W ...
When power is applied to a stator winding, the rotor's magnetic reluctance creates a force that attempts to align a rotor pole with the nearest stator pole. In order to maintain rotation, an electronic control system switches on the windings of successive stator poles in sequence so that the magnetic field of the stator "leads" the rotor pole ...
The EMD MP15AC is a 1,500 hp (1,120 kW) diesel road switcher locomotive built by General Motors' Electro-Motive Division between August 1975 and August 1984. A variant of the EMD MP15DC with an AC/DC transmission, 246 examples were built, including 25 for export to Mexico, and four built in Canada.
When providing the maximum 500 kW HEP load, maximum traction power is reduced to 2,930 hp since HEP generation diverts some power from the prime mover. [4] The MP36PH-3S was the first variety of MPXpress locomotive to be built and the launch customer was Metra, a commuter railroad in the Chicago area. Metra ordered 27 of these locomotives in ...
An output signal switching device (OSSD) is an electronic device used as part of the safety system of a machine. It provides a coded signal which, when interrupted due to a safety event, signals the machine to shut down. It works by converting the standard direct current supply, usually 24 volts, into two pulsed and out-of-phase signals.
High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. [1] The technology has been improved over time and can now be used with voltages up to 1,100 kV. [2] Typically, switchgear in substations is located on both the high- and low-voltage sides of large power transformers. The ...
MP10, MP 10, or MP-10 may refer to: MP 10, a zone during the Eocene epoch; Mario Party 10, a 2015 Wii U video game; Heckler & Koch MP5/10, an MP5 submachine gun clone
