ABB UNS2880b-P,V2 3BHE014967R0002 Permanent magnet excitation system

Description

ABB UNS2880b-P,V2 3BHE014967R0002 is another main classification of electrical excitation system. It uses permanent magnet materials (magnets, strong magnets, etc.) to generate a spontaneous magnetic field under the action of external electromagnetic effects, thereby promoting the performance of the motor. Compared with the electric excitation system, the advantages of the permanent magnet excitation system are: the resistance to external interference is relatively strong, and the maintenance cost is low. At the same time, the permanent magnet excitation system does not require additional power or voltage, and only needs an exciting magnet to complete the excitation, which is generally welcomed by design engineers.

Excitation system can improve the mechanical and motor performance and work efficiency, but also can reduce the risk of failure, protect the stability of motor operation. The classification of excitation system has electrical excitation system and permanent magnet excitation system, they have their own advantages and disadvantages, but also have their own characteristics. The characteristic of the electric excitation system is that the performance optimization is convenient and economical. The permanent magnet excitation system is known for its low degree of external interference, easy maintenance, and high practicability.

In short, the excitation system belongs to the motor speed control of a technology, it uses external electromagnetic potential energy to change the dynamic performance of the electromechanical system, can effectively improve the performance of the motor, to provide the motor and stable control mode, so as to achieve energy saving and emission reduction, to meet the working requirements at different speeds, to ensure the safe operation of the motor. To provide users with multi-mode, beyond the traditional motor control scheme, expand the scope of motor control.
