Synchronous Alternator of High-Performance: EvoTec Power Provided
Publish Time: 2023-01-14   Views: 22

A synchronous alternator is an alternator of AC. Since the rotor rotates at the same speed as the rotating magnetic field generated by the stator winding, it is called a synchronous alternator. EvoTec Power is a professional manufacturer of synchronous alternators. They are here today to explain how the synchronous alternator works and what the benefits of using their high-performance synchronous alternators can bring to your company's production.

What is a synchronous alternator?

A synchronous alternator is an electrical power supply infrastructure that converts other forms of energy into electrical energy and has a consistent magnetic field. It is driven by a water turbine, steam turbine, diesel engine, or other power machinery. It converts the energy generated by water flow, airflow, fuel combustion, or nuclear fission into mechanical energy into electrical energy. Because it supports various mechanical energy sources, synchronous alternators have various applications in industrial and agricultural production, national defense, science and technology, ore mining and refining, and everyday life.

The working principle of the synchronous alternator is based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is using appropriate magnetic and conductive materials to form a magnetic circuit and circuit for mutual electromagnetic induction to generate electromagnetic power to achieve the purpose of energy conversion.

EvoTec Power would like to introduce key factors in choosing the right synchronous alternator.

The performance of a synchronous alternator is mainly reflected by the no-load characteristics and the load-running characteristics. These characteristics are important for the user to choose a generator.

No-load characteristics.

When the generator is not connected to a load, the armature current is zero, called the no-load operation. At this time, the three-phase winding of the motor stator only excitation current induced no-load electric potential (three-phase symmetric); its size increases with the increase. However, the two are not proportional to each other because of the saturation phenomenon in the core of the magnetic motor circuit. The curve reflecting the no-load electric potential about the excitation current is called the no-load characteristic of the synchronous generator.

Load operating characteristics.

Mainly refers to the external characteristics and adjustment characteristics. The external characteristic is the relationship between the generator terminal voltage U and the load current I when the speed is rated. The excitation current and load power factor are constants. The adjustment characteristic is the relationship between the excitation current If and the load current I when the speed and end voltage are rated, and the load power factor is constant.

Conclusion

The voltage variation rate of synchronous generators is about 20 to 40%. For industrial applications, especially for power plants and other industries with high requirements for power supply stability, the voltage is required to remain essentially constant. EvoTec Power's alternator has an excellent adaptive function that guarantees a stable and reliable power output.
