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 ...
Doubly fed induction generator (DFIG), a generating principle widely used in wind turbines. It is based on an induction generator with a multiphase wound rotor and a multiphase slip ring assembly with brushes for access to the rotor windings. It is possible to avoid the multiphase slip ring assembly, but there are problems with efficiency, cost ...
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 rotary converter can be thought of as a motor–generator, where the two machines share a single rotating armature and set of field coils. The basic construction of the rotary converter consists of a DC generator (dynamo) with a set of slip rings tapped into its rotor windings at evenly spaced intervals. When a dynamo is spun the electric ...
Motor–generator sets have been replaced by semiconductor devices for some purposes. In the past, a popular use for MG sets was in elevators . Since accurate speed control of the hoisting machine was required, the impracticality of varying the frequency to a high power AC motor meant that the use of an MG set with a DC hoist motor was a near ...
1995, the company sets up a new plant and offices of 15,000 m 2 in Guipavas, near Brest. 2001: three subsidiaries are opened in Argentina, Brazil and the United-States and a representative office is set up in Algeria. 2003: a subsidiary is set up in Belgium; 2005: a subsidiary is set up in Nigeria; 2006: a representative office is set up in Dubai
