A Dahlander motor (also known as a pole changing motor, dual- or two speed-motor) is a type of multispeed three-phase induction motor, in which the speed of the motor is varied by altering the number of poles; this is achieved by altering the wiring connections inside the motor. The motor may have fixed or variable torque depending on the ...
A wiring diagram for parts of an electric guitar, showing semi-pictorial representation of devices arranged in roughly the same locations they would have in the guitar. An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing.
The initial "T700-GE-700" is an ungeared free-turbine turboshaft, with a five-stage axial / one-stage centrifugal mixed-flow compressor, featuring one-piece "blisk" axial stages, with the inlet guide vanes and first two stator stages variable; an annular combustion chamber with central fuel injection to improve combustion and reduce smoke; a ...
Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...
In the late 1980s, GE used the GE27 as the basis for the commercial development of turboshafts, turboprops, turbofans, and propfans under the GE38 name. GE formed a 50/50 venture with Garrett (then a division of AlliedSignal) to develop the turbofan variant [5] called the CFE (Commercial Fan Engines) CFE738, which used the GE27's gas generator ...
GE GEVO-16, 16-cylinder engine used in locomotives, such as the GE ES59ACi, [6] GE ES58ACi, [6] GE ES57ACi Diesel Locomotives. HDL series [1] GE 7HDL-16, 16-cylinder engine used in only the GE AC6000CW [7] L250. GE L250 Series, 6- and 8-cylinder marine engines for propulsion and electric generator usage [8] PowerHaul series
compressor handling at part speed is facilitated by several rows of variable pitch stators at the front part of the unit. This was a fairly novel feature when the engine was first introduced. a single stage power turbine. which delivers power to the rear of the engine.
An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. For a four-pole motor (two pairs of poles on stator) powered by a 60 Hz source, the synchronous speed is 1800 rotations per minute (rpm) and 1500 RPM powered at 50 Hz. The motor always turns slightly slower than the synchronous speed.
