Motor-Generator Set

A motor–generator (an M–G set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line. Large motor–generators were widely used to convert industrial amounts of power while smaller motor–generators (such as the one shown in the picture) were used to convert battery power to higher DC voltages.

At lower voltages, the task of converting electrical energy from AC to DC may be performed by a converter (ie without moving parts). So, as an analogy, you may wish to imagine that a MG Set is a larger, mechanical, AC to DC converter.

Several MG Sets exist but the most famous one controls the Recirc Pump speed via a Scoop Tube.
