Jiaxing bearing | know the working principle of magnetic bearing and classification?

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. According to the working principle of magnetic bearing system can be divided into three categories: active magnetic bearings ( ActiveMagneticBearing) And passive magnetic bearings ( PassiveMagneticBearing) , hybrid magnetic bearing ( HybridMagneticBearing) 。 1, active magnetic bearing active magnetic bearing with controllable electromagnetic force will be rotating shaft is suspended, it is mainly composed of rotor, magnet, sensor, controller and power amplifier, etc. Suspension electromagnet is installed on the stator, rotor in the radial symmetry placed in the magnetic field generated by the electromagnet, all equipped with one or more sensors on each of the electromagnet, with continuous monitoring changes the position of the rotor. Signal from the output of the sensor, with the aid of electronic control system, and the correction by electromagnet of current, to control the attraction of the electromagnet, the rotating shaft in the stable equilibrium state, and achieve a certain accuracy requirement. Deviate from the reference point of displacement sensor to detect the rotor, as the microprocessor of the controller will detect the displacement transform into a control signal, then the - power amplifier - Control signal into control current, control current in the execution of electromagnet produce magnetic force so that to maintain its stable suspension rotor position unchanged. Suspension stiffness and damping of the system and the stability is determined by the control system. 2, passive magnetic bearings, passive magnetic bearings as a form of magnetic bearings, has its own unique advantages, it is small in size, power consumption, simple structure. Passive magnetic bearings and the difference from the active magnetic bearings, the former no active electronic control system, but the use of the characteristics of magnetic field itself will be a shaft is suspended. For now, in the passive magnetic bearings, applied the most were composed of permanent magnet magnetic bearing. Permanent magnetic bearing and can be divided into repulsion type and suction type two kinds. 3, hybrid magnetic bearing hybrid magnetic bearing is in active magnetic bearings, passive magnetic bearings, and other auxiliary support and stable structure formed on the basis of - - Kind of combined magnetic bearing system. It takes a comprehensive characteristics of active magnetic bearings and passive magnetic bearings. Hybrid magnetic bearing is the use of magnetic fields produced by permanent magnets to replace the electromagnet static bias magnetic field, it can not only reduce the power consumption of the power amplifier, and can reduce the electromagnet ampere turn - Half, narrow the volume of magnetic bearings and improve the bearing capacity and so on.
