The EMD GT26 Locomotive Series made their debut in 1967 after the rise in popularity of the American EMD SD40.Designed to meet most First World, Second World and Third World countries, the GT26 Series were now equipped with a turbocharged high horsepower EMD 645 Series engine as well as six axle HT-C trucks to provide better traction effort at slow speeds.
A synchronous electric motor is an AC electric motor in which, at steady state, [1] the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integer number of AC cycles.
The EMD 645 is a family of two-stroke diesel engines that was designed and manufactured by the Electro-Motive Division of General Motors.While the 645 series was intended primarily for locomotive, marine and stationary engine use, one 16-cylinder version powered the 33-19 "Titan" prototype haul truck designed by GM's Terex division
Bars and rings of the damper (amortisseur) winding of an AC generator (General Electric, early 20th century). Note the gaps in the cage along the quadrature axes. The damper winding (also amortisseur winding [1]) is a squirrel-cage-like winding on the rotor of a typical synchronous electric machine. It is used to dampen the transient ...
In this way, applying power to the "open damper" terminal causes the motor to run until the damper is open while applying power at the "close damper" terminal causes the motor to run until the damper is closed. The motor is commonly powered from the same 24 volt AC power source that is used for the rest of the control system. This allows the ...
A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. The rotor does not have any windings. It generates torque through magnetic reluctance. Reluctance motor subtypes include synchronous, variable, switched and variable stepping.
The synchronous reactances are exhibited by the armature in the steady-state operation of the machine. [8] The three-phase system is viewed as a superposition of two: the direct one, where the maximum of the phase current is reached when the pole is oriented towards the winding and the quadrature one, that is 90° offset.
I removed this line. "The last locomotives the 645 were installed in were the export models G22CU-2 and G26MC-2 for Taiwan and Indonesia in 2001. " As new production 645 engines are used in the MPI MP36PH line of locomotives and Saudi Arabia received 645 powered SDL50's from EMD as recently as 2005. --Chesapeake 01:11, 24 March 2008 (UTC)
