Starlight generator

Definition of permanent magnet DC generator Permanent magnet DC generator is a kind of power generation device which transforms mechanical energy into electrical energy. It is a kind of permanent magnet DC generator with double permanent magnet and double winding structure. Principle of permanent magnet DC generator It is same as AC generator, using the electromagnetic induction principle of the electric potential induced by the cutting of the magnetic line of force to transfer the mechanical energy of the prime mover into electrical energy, then output electrical energy. It is composed of stator and rotor. The stator is the armature that generates electricity, and the rotor is the pole. The stator is composed of armature core, three-phase winding with uniform discharge, base and end cover, etc. The rotor is usually of hidden pole type, which consists of excitation winding, iron core and shaft, retaining ring, central ring, etc. The exciting winding of the ro...

Generally, we should change engine oil of diesel generator once time after 500 hours' operation, but sometimes the oil becomes thinner and impurities increase before the replacement period, so it can not be used continuously. Starlight Power shares some reasons with you. Why Is Engine Oil Fast to Deteriorate in Diesel Generator? 1.The part number of engine oil is incorrect, the quality fails to meet the standard requirements. We should select the engine oil which meet CC grade or above for the diesel generator with supercharging and rated speed greater than 2000 R/min; 2.Technical condition of   diesel engine generator   is not good, and the blowby gas, oil, fitting clearance are too large or the oil temperature is too high; 3.Diesel generator set often operates at low temperature, low load and low speed. The piston deformation is not enough and the combustion is not complete. Diesel oil enters the oil pan along the cylinder wall to dilute the engine oil; 4.Waste ...

1.Use the starting battery (12V) of the diesel engine to power on the excitation wire (2 carbon brush wires) for a few seconds. It is better to magnetize it during operation. As soon as the battery contacts the excitation wire, the generator magnetizes and circulates to increase the magnetic field. 2.It should be noted that the time of grounding should not be too long, and that the speed of the diesel engine is slightly higher, it is better to carry a load, and connect an electric lamp, so as to know whether the magnetization is successful at any time. The reasons of no electricity in Volvo generators : 1.After shutdown, the remanence is often lost because the material used for the exciter pole is close to soft steel, and the remanence is small. When there is no current in the excitation winding after shutdown, the magnetic field disappears. 2.The pole of the generator loses magnetism. 3.The excitation circuit element is damaged or the circuit has open circuit,...

The diesel generator and voltage regulator have been had matching test at the factory. Therefore, when loading and using, the 200kw Cummins genset and voltage regulator shall be installed and used together with the same number and the same ex factory date.  Only acceptance test shall be carried out by the user. If the generator and voltage regulator are overhauled, the components affecting the electromagnetic performance have changed, or the number of the generator and voltage regulator are different, the matching test must be carried out. The test steps are as follows: 1.Appearance inspection: the generator and voltage regulator shall be intact, all screws shall be free of looseness, and the rotor shall rotate flexibly without friction, otherwise, they shall be disassembled for inspection. 2.Connect the steam pipe, connect the high-pressure steam, no-load for several minutes, and measure the speed within the rated range. Measure the voltage between the tw...
