Features of MSC Series Maglev Motor

The magnetic levitation controller has high reliability and strong stability,with self calibration and self identification functions. It can achieve adaptive adjustment and control as the operating time of the magnetic levitation equipment increases, without the need for manual intervention,avoiding risks such as downtime.Vibration caused by mass unbalance is a common problem in rotating machinery. Perfect balance can make the rotor assembly center completely coincide with its inertial principal axis, but it is difficult to achieve for rotor of maglev motor with impeller and multiple components, because the imbalance may change during rotor operation (for example,the influence of thermal deformation or ash layer.). As for the residual imbalance of the rotor, the negative feedback control +UFRC algorithm is adopted to make the rotor rotate around its inertial main shaft at each speed, eliminating reaction force on bearing and excitation force on the whole machine; finally, it effectively ensures the long-term reliable oper- ation.By sweeping the frequency from 0 to 2000Hz, the natural frequency of rotor and the whole machine can be measured before rotor rotates, the rotating condition can be simulated to make fault prediagnosis. When machine is working, the anti-interference performance is measured by sweeping to ensure each machine' s stability.

Motor Components

High speed permanent magnet motors have the advantages of small size, high power density, high efficiency, and direct connection with loads, making them the preferred choice for application in the blower industry. We conducted research on high-speed permanent magnet motors based on optimization of motor electromagnetic schemes, design of cooling systems, and dynamic analysis of rotor systems, and established an analytical model for the BOKES brand series MSC motors.

Axial and Radial Magnetic Bearings

Combining electromagnets, power amplifiers, displacement sensors, and electronic control systems, a design optimization model for magnetic levitation bearings is constructed, with the goals of maximum bearing capacity, minimum eddy current loss, and minimum coil heating loss. The geometric structure of the bearings is optimized to improve system reliability and reduce system power consumption.

UFRC Control System

Unbalance Force Rejection Control (algorithm of revolving around the center of mass) enables the rotor to rotate around the inertial spindle. The advantages of this algorithm: for the inevitable residual unbalance of rotor, by making the rotor rotate around its inertial spindle at each speed, the reaction force transmitted by the bearing and the excitation force brought to the entire machine can be eliminated, so that can effectively ensure the long-term reliable operation.

Integrated Design of Maglev Blower

The blower features the integrated design of "electrical,mechanical and electronic". It comprises the pneumatic unit of ternary flow impeller and volute shell, the high-speed frequency inverter and the maglev motor drive unit, and the central control unit for motor suspension and blower operation.

The Principle of Maglev Blower

MSC series maglev centrifugal blower adopts active magnetic bearing and high-speed permanent magnet synchronous motor. It is directly driven by ternary flow impeller, levitating the rotor system through magnetic force, and generating kinetic energy by high-speed rotating impeller to achieve blowing function.

New Ternary Flow Impeller

Based on three-dimensional flowing theory, the ternary flow impeller is designed with multi-curved blade, so that the flow channel is more adapted to the true flow state of fluid. The CFD analysis is used to solve complex calculation of quantitative value of three-dimensional flow of the blade, so that improves the efficiency, reliability, and safety of blower. Through ternary optimization, the flow loss in the flow channel is reduced, the influence of separation flow, vortex, secondary flow and other effects on the aerodynamic performance are reduced, and then an optimized design that conforms to air flow is finally obtained.

High-Speed Permanent Magnet Motor

High speed permanent magnet motors have the advantages of small size, high power density, high efficiency, and direct connection with loads, making them the preferred choice for application in the blower industry. We conducted research on high-speed permanent magnet motors based on optimization of motor electromagnetic schemes,design of cooling systems, and dynamic analysis of rotor systems, and established an analytical model for the BOKES brand series MSC motors.

Features of MSC Series Maglev Blower

Compared with Roots blower's efficiency, maglev blower's efficiency increased 30%~40%. Taking the 160kW maglev blower as an example, each blower can save more than 500,000 kWh electricity and ￥300,000 in bills per year.Maglev blower is lubricant-free; the air transmitted is pollution-free. The Maglev bearing is frictionless and operates without noise, bringing no effect to the surrounding office and living environment. take 160kW maglev blower for example, each blower can reduce carbon dioxide emissions by approximately 500 tons per year.High performance frequency converter is adopted to control 25% speed. Advanced control system is adopted to provide multiple control modes. The turntable can monitor running process and can be controlled remotely, saving labor costs. Fully enclosed water-cooling and air-cooling system are adopted to dissipate heat from motor, ensuring stable running and prolonging blower's service life. Modular design makes it easy to maintain.Frictionless maglev bearing reduces product damage and extends blower's service life to 20 years or more. Maglev blower is easy to maintain, requiring only regular filter change. The maglev blower is lubricant-free, which saves the cost of lubricating oil and cleaning. The motor adopts direct drive, small size, light weight, and space saving. Domestic production ensures timely supply of spare parts
