Working Principle and Structure of EECTECH Maglev Bearing/Magnetic bearing

Active control magnetic suspension bearing is a device which uses the current in the solenoid coil to produce non-contact controllable electromagnetic
force to make the rotor run in a stable suspension state in space. It involves rotor dynamics, mechanics, electronics, control engineering, magnetic
materials and testing technology.Technology, Digital Signal Processing and Other Multidisciplinary Technologies

Characteristics and Advantages-Technological Progress


Comparison with contact bearings - Maglev bearing enjoys many advantages

Performance

Traditional Contact bearing

Maglev bearing

Speed

<10,000 rpm

RPM Up to hundreds of thousands

Lubrication

The lubrication system is complex and bulky

No lubrication required,

the whole machine structure can be reduced by half.

Energy consumption

Contact abrasion, high energy consumption

< 1/10 of Contact bearing,

the whole machine can save more than 40% energy.

Temperature

The working temperature generally does not exceed 100 C.

It can work in high and low temperature environment

and could operated at 550 C for long time.

Life time

Less than 8 years, need to be disassembled and replaced

It has a life of more than 20 years

no need to be disassembled or maintained.

Stability

Unable to actively control, poor stability

can actively control & adjust the dynamic behavior of the rotor with high stability, real-time monitoring and high reliability.




Characteristics and Advantages-Economy

Taking the aerator for water treatment as an example, the Roots blower with traditional bearings is compared with the magnetic suspension blower with magnetic suspension bearings.
1. Maglev blower can save more than 40% energy than Roots blower.
2. The medium-sized sewage treatment plants with daily capacity of 50,000 tons adopt magnetic suspension blowers, which can save 1.5 million degrees of electricity per year.
3. In 2013, there were 3114 sewage treatment plants with daily treatment capacity of more than 5000 tons in cities and towns, which saved 3.849 billion yuan of electricity per year.




Characteristics and Advantages-Structural Advantages




Characteristics and Advantages-User Experience Advantages

Environmental protection and low noise
1. Running quietly, the noise at 1m of the whole machine is lower than that at 1m.80dB, no need to install additional sound insulation device.
2. Small vibration, almost no sense of equipment when running.Vibration reduces the requirement of equipment foundation.
3. Clean and tidy environment, clean equipment and upgrading work Environmental quality.

Intelligent control
1. LCD touch screen control, operating conditions at a glance, real-time display of process parameters.
2. It can be controlled remotely and adjusted by multi-equipment linkage, so as to achieve the best use efficiency.
3. Various control modes to meet different production control needs.
