Generator Terminology

- Nov 10, 2017-


The general term for a device that converts mechanical energy into electrical energy. The resulting electrical energy may be direct current (DC) or alternating current (AC).


Refers to the connection between the circuit and the earth or between (and intentionally or accidentally) between the conductive objects that communicate with some and the earth.

Idle control

A system that can control the engine's idling speed directly from the electrical load.

Ignition coils

A device that provides a DC voltage for a spark plug.

Permanent magnet generator

An alternating current generator with permanent magnets for generating the current required for ignition of the internal combustion engine.


Resistance unit. A 1 volt voltage allows 1 amps of current to flow through a 1 ohm resistor.


The amplitude or magnitude of alternating current is uniform and cyclical. Three-phase alternating current consists of three different sine wave current, the phase difference between each other are 120 degrees.

Power conversion system

The system can safely connect your generator to your home electricity system.

Rated speed

Unit design work speed (revolutions per minute).

Rated voltage

The rated voltage of a set of engine generators is the design of the operating voltage.

Rear bearing bracket

A castor used as a rotor bearing housing. The rotor bearing supports the rotor shaft.


A device that converts alternating current into direct current.


Is the DC power (battery, battery) into alternating current (usually 220v50HZ sine or square wave).


An electric switch, usually used in a control circuit. Compared with the current contactor, its contacts can only pass a smaller current.


Resistance to current.


The rotating element of the generator.


An AC load or power supply, usually, if it is a load, there are only two input terminals, and if it is a power supply, there are only two output terminals.


The rest of the motor.

Vibration bracket

A rubber device located between the engine or the generator and the rack can minimize vibration.


Electromotive force unit. The unit electromotive force is constantly applied to a conductor with a resistance of 1 ohm, which will produce 1 amps of current.


The potential difference is expressed in volts.


The device automatically keeps the generator voltage at a correct value by controlling the amount of DC power that energizes the rotor.


Power unit of power. For DC, it is equal to the volt multiplied by amperes. For alternating current, it is equal to the voltage rms (volts) multiplied by the current rms (amperes) multiplied by the power factor multiplied by a constant (its value depends on the number of phases). 1 kW - 1000 Watt.


All the coils of the generator. The stator windings consist of a number of stator coils and their interconnection lines. The rotor windings consist of all windings and wires on the rotor pole.


There are many kinds of generators. From the principle is divided into synchronous generators, asynchronous generators, single-phase generators, three-phase generators. From the production methods are divided into turbo generators, hydro-generators, diesel generators, gasoline generators and so on. From the energy is divided into fire generators, hydroelectric generators and so on.
