A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG). Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo, the armature windings generate the electric current, which provides power to an external circuit.
The rotor of a turbo generator is a non-salient pole type usually with two poles. [5] The normal speed of a turbo generator is 1500 or 3000 rpm with four or two poles at 50 Hz (1800 or 3600 rpm with four or two poles at 60 Hz). The rotating parts of a turbo generator are subjected to high mechanical stresses because of the high operation speed.
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...
The motor–generator set may contain a large flywheel to improve its ride-through; however, consideration must be taken in this application as the motor–generator will require a large amount of current on re-closure, if prior to the pull-out torque [clarification needed] is achieved, resulting in a shut down. The in-rush current during re ...
The GE 7FDM, also known as the GE V228, is a series of marine engines from GE Transportation Systems for propulsion and electric generator usage. Engine model numbers for the 7FDM series of engines take the form of 7FDMXXZYY, where XX is the number of cylinders, Z is the engine series, and YY is an additional differentiator between engines.
GE L250 Series, 6- and 8-cylinder marine engines for propulsion and electric generator usage [8] PowerHaul series. GE PowerHaul P616, 16-cylinder engine used in GE PowerHaul series locomotives. [9] V228 (formerly 7FDM) (Bore 9"/228.6mm, stroke 10.5"/266.7 [10])
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
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.
