How to buy a generator?

The motor of the diesel generator, that is, the generator, its function is to convert the power of the diesel engine into electrical energy, which is directly related to the quality and stability of the output power. Users are advised to consider the stator coil and excitation method when purchasing a motor.

 

The generator mentioned here refers to the motor of the diesel generator. Its function is to convert the power of the diesel engine into electrical energy, which is directly related to the quality and stability of the output power. When purchasing a motor, we can make key trade-offs from the stator coil and the excitation method.

 

The first point of purchase: the stator coil of the generator

 

The stator coil was originally made of all copper wire, but with the improvement of wire making technology, copper clad aluminum core wire appeared. Different from copper-plated aluminum wire, copper-clad aluminum core wire is made of copper-clad aluminum using special molds when drawing the wire, and the copper layer is much thicker than copper-plated. The performance of the generator stator coil using copper-clad aluminum core wire is not much different, but the service life is much shorter than that of the all-copper wire stator coil. Therefore, Tingbo Power recommends users to choose all-copper wire generators, which can improve their service life.

 

The second point of purchase: the excitation method of the generator

 

The generator excitation mode is divided into phase compound excitation type and brushless self-excitation type. The brushless self-excitation type has become the mainstream with the advantages of stable excitation and simple maintenance, but there are still some manufacturers who configure phase compound excitation generators in generator sets below 300KW due to cost considerations. Here, Tingbo Power recommends users to choose a brushless self-excited generator, which can improve the stability of the unit and the convenience of maintenance.
