Modification project of 200KW speed-regulating magnetic coupler for fan in jingkedaihai power plant
The magnetic coupler and the permanent magnet speed control device are mainly composed of a copper rotor, a permanent magnet rotor and a controller. Generally, the copper rotor is connected to the motor shaft, the permanent magnet rotor is connected to the shaft of the working machine, and there is an air gap (called an air gap) between the copper rotor and the permanent magnet rotor, and there is no mechanical connection for transmitting torque. In this way, a soft (magnetic) connection is formed between the motor and the working machine, and the torque and the rotational speed of the working machine shaft are changed by adjusting the air gap. Because of the different air gap adjustment methods, the magnetic coupler and the speed control device are divided into different types such as fixed type, limited moment type, mining limit type, speed regulation type, and mine speed regulation type.
The permanent magnet eddy current transmission technology is not simply a principle of utilizing the same-sex repulsive and opposite-phase attraction of the magnet. It is the integration of transmission technology, material technology and manufacturing technology. In the 21st century, manufacturing technology will not only continue to manufacture machines and equipment operating under normal conditions, but also to manufacture mechanical equipment operating in extreme environments. Products manufactured in the 21st century should be energy-saving and eco-friendly, human-friendly green products, permanent magnets. The eddy current transmission technology is adapted to this development trend. With the emergence of new technologies, new processes, new materials and new structures, a new stage of the development of permanent magnet eddy current transmission technology is bound to usher.
