A DC generator is a device that converts mechanical energy into DC electrical energy. It is mainly used as DC motor for DC motor, electrolysis, electroplating, electric smelting, charging and excitation of AC generator.
1.All generator sets are equipped with four-stroke engines.
2.High effective combustion system ensures complete combustion, Besides, a large silencer dampens exhaust noise and engine sounds which are contained by a double-wall structure and absorbed by a liner.
3.All the control units of the generator sets are on one panel, a monitor of the panel will display the real-time working data of the generator set such as its output voltage and current etc.
4.Before the oil level drops to the limited level, the generator set will stop automatically. The whole set can be restarted only if the oil is refilled.
5.The AVR (Automatic Voltage Regulator) not only can smooth the output but also can provide reasonable protec-tion against the overload of the whole set, thus avoid damage to the set.
6.Waveform distortion is kept at a minimum level and the output is stable. The winding design protects the generator from short circuits and provides a stable output while running inductive loads.
7.On the inheriting of the original general-purpose generator set, VLAIS diesel generator sets with digital control panel can be equipped with a made ATS(automatic transfer switch). ATS, in its preset intervals, can automatically check and monitor the running of the genset to ensure the genset in good working condition. Meanwhile, ATS will monitor the utility power, if utility power fails or the voltage and frequency of the utility power become abnormal, ATS will give commands to start the genset automatically.
Although DC rectifiers are also used in places where DC power is needed, AC power is converted into DC power. However, from the perspective of ease of use, operational reliability, and some performance, DC motors are not yet comparable to AC generators. The DC generator has a better potential waveform and less electromagnetic interference, but because of the presence of a commutator, its manufacturing and maintenance are complicated and the price is high.
The working principle of the DC generator is to convert the alternating electromotive force generated in the armature coil by the commutator with the commutation effect of the brush to make it become a DC electromotive force when it is pulled out from the brush end because the brush A passes the commutation. The electromotive force drawn from the sheet is always the electromotive force in the coil edge that cuts the N-pole magnetic field lines. Therefore, brush A always has positive polarity. Similarly, brush B always has negative polarity. Therefore, the brush end can lead to a pulsating electromotive force with a constant direction but a change in size.
1. The stationary part of a DC motor is called the stator Action-generate a magnetic field Composed of main magnetic pole, commutating pole, base and brush device, etc.
2. The rotating part of the DC motor is called the rotor (usually called the armature) Role-generating electromagnetic torque and induced emf Composed of armature core and armature winding, commutator, shaft and fan, etc.
