1. Motor-generator

   A motor-generator 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 were used to convert battery power to higher DC voltages. Low-powered devices such as vacuum tube mobile radio receivers did not use motor-generators. Instead, they would typically use an inverter circuit consisting of a vibrator and a transformer to produce the B+ voltages required for the vacuum tubes. While a motor-generator set may consist of distinct motor and generator machines coupled together, a single unit motor-generator will have both rotor coils of the motor and the generator wound around a single rotor, and both coils share the same outer field coils or magnets. Typically the motor coils are driven from a commutator on one end of the shaft, when the generator coils output to another commutator on the other end of the shaft. The entire rotor and shaft assembly is smaller in size than a pair of machines, and may not have any exposed drive shafts.

1. Motor-Generator

   A combined motor and generator used to lower the potential difference in a portion of a circuit, e. g., that part within a building. A motor-generator is a dynamo whose armature carries two commutators, with two separate windings, one of fine wire of many turns, the other of coarse wire of few turns. If the potential of the system is to be lowered, the main current is passed through the fine winding. This causes the armature to turn motor-fashion, and a potential difference is generated by the rotation of the large coils in the field. This potential difference is comparatively low and by properly proportioning the windings may be lowered to as great a degree as required. The same apparatus may be inverted so as to raise potential difference. It acts for continuous current systems as the induction coil transformer does for alternating current systems. Synonym--Continuous Current Transformer.
