Magnetic Suspension Turbo Fan
When a magnetic suspension fan suddenly loses power due to an accident, the permanent magnet motor will continue to rotate due to the inertia generated by its previous rapid rotation. During this rotation, it will continue to generate some electricity.
Magnetic Suspension Jet Propeller Sudden Power LossWhen the magnetic suspension propeller suddenly loses power due to an accident, the permanent magnet motor will continue to rotate due to the inertia caused by its previous high speed. During this rotation, it will continue to generate some electricity, which will be supplied to the magnetic bearings through the reverse voltage circuit. As the rotational speed of the magnetic bearings gradually decreases, the blower shaft gradually lowers onto the spare protective bearings (contact angle ball bearings) and continues to rotate slowly until the blower shaft stops rotating. This double anti-drop action effectively protects the magnetic bearings and propeller shaft, prolonging the life of the blower. Regular ShutdownDuring the normal shutdown process, the magnetic bearings remain in a floating state. Only after the fan has stopped safely do the bearings come down, protecting the magnetic bearings and...
During normal shutdown, the magnetically levitation bearings remain in a floating position. Only after the fan has safely come to a stop do the bearings descend, protecting the magnetic bearings and the fan shaft. This significantly extends the lifespan of the magnetic bearings and the blower.
