Permanent magnet governor
What is a permanent magnet governor? It is a revolution in the history of transmission. Its simple structure, reliable operation, energy saving and consumption reduction features are well applied in modern industry. It is mainly used in the energy saving of motor drive systems in petroleum, petrochemical, electric power, mining, steel, chemical, cement and other industries. The structural composition of the permanent magnet speed governor: the regulator adjusts the relative position of the cylindrical permanent magnet rotor and the cylindrical conductor rotor in the axis direction to change the effective part of the coupling between the permanent magnet rotor and the conductor rotor, which can change the torque transmitted between the two, achieve repeatable, adjustable and controllable output torque and speed, and achieve the purpose of speed regulation and energy saving. Permanent magnet speed governor is mainly composed of three parts: permanent magnet rotor, conductor rotor and speed governing mechanism. Power range: as of the end of 2016, the maximum power equipment of air-cooled permanent magnet speed governor can be 710kW and 1000r/min in the whole permanent magnet drive industry; The maximum power equipment of water-cooled permanent magnet governor can be 3000kW and 1500r/min. Technical features of permanent magnet speed governor: smooth stepless speed regulation, speed regulation range 0-98%, high efficiency and energy saving, power saving rate 10-50%. Simple, reliable, mechanical structure, without external power supply. Flexible start, reduce the impact current of the motor, and extend the service life of the equipment. Vibration isolation, no mechanical connection. It is easy to install and can tolerate large alignment errors. It can adapt to various harsh environments, including places with large fluctuation of power grid voltage, serious harmonics, flammability, explosion, humidity, dust, etc. Extend the service life of the main components (bearings, seals, etc.) of the transmission system and reduce the maintenance cost. Green and environmental protection, no harmonics, no pollutants, no EMI (electromagnetic wave) interference. Long service life, up to 30 years. High investment efficiency and fast investment recovery.
