Magnetic bearings have been widely used from military to civilian applications.
1. CNC machine tool: CNC lathe uses a five axis controllable magnetic bearing high-speed spindle, which adopts two radial magnetic bearings and one axial thrust magnetic bearing, and can withstand the load of the machine tool in any direction.
2. High speed milling spindle: The milling spindle currently developed has a fast rotation speed, and the diameter of this type of spindle can be very large, far higher than other types of milling spindles.
3. Grinding machine: The grinding wheel shaft and spindle are both developing towards high-speed, and magnetic bearings are used to further increase the speed.
4. Fan motor: Make the motor a five axis control type, which controls a total of 5 degrees of flexibility for 4 radially and 1 axially.
5. High vacuum molecular pumps: Vacuum molecular pumps do not require maintenance or forced cooling, and their vibration and noise are 1/10 of those of previous products
6. Magnetic levitation flywheel satellite application: used for a system on a satellite that integrates attitude control/retrieval capabilities.
7. Artificial heart impeller blood pump: the traditional artificial heart has many shortcomings. In the new type of Artificial heart, the blood delivery is completed by the centrifugal force generated by the impeller driving the blood flow rotation. The increase of blood pressure and flow can be achieved through the impeller speed.
8. Engines from various industries: Install electric starters/generators on high-speed rotors, replace mechanical transmission accessories with fully electrified accessories, and develop the power transmission system of the engine from traditional mechanical transmission to fully electrified transmission.
9. Magnetic bearing Electricity meter: the application of long-life Electricity meter is widely used. The magnetic bearing for Electricity meter is divided into two categories: magnetic thrust bearing and magnetic suspension bearing.
10. Centrifugal compressors and expansion turbines: Due to their non-contact nature, they can increase the shaft diameter and control vibration, resulting in higher rotational speeds for the same output compared to using ordinary bearings.
11. Flywheel energy storage system: Flywheel energy storage has the advantages of collection and storage, rapid release, high efficiency, simple maintenance, long service life, small footprint, and decentralized distribution.
12. Uninterruptible power supply for communication: It is a constant voltage and frequency power supply device that contains energy storage devices and is mainly composed of inverters.
13. Electromagnetic gun: the traditional gun or rocket is launched with the Chemical energy of propellant, while the electromagnetic launcher using electromagnetic launch technology uses electromagnetic energy or electromagnetic force to launch objects.
14. Magnetic Bearing Spindle: On the basis of protecting the existing dimensions of the spindle and protecting the mechanical positioning of the spindle on the spindle rod, an attractive magnetic bearing composed of annular anisotropic permanent magnets is installed at the lower end of the spindle rod to implement axial and radial magnetic constraints on the spindle rod, in order to extend the service life of the spindle and save energy consumption.
