The magnetic levitation control system consists of a controller, rotor, magnetic bearing, sensor, and power amplifier. Compared with traditional mechanical bearings, sliding bearings, and oil-lubricated bearings, magnetic bearings have no mechanical contact. The rotor can achieve very high rotational speeds, offering features such as no friction, low energy consumption, high efficiency, low noise, long service life, no need for lubrication, and no pollution. These characteristics make it especially suitable for high-speed, vacuum, ultra-clean, and other special environments.
- Displacement Sensor：Detects displacement signals of the rotor.
- Controller：Processes signals through adjustment, computation, and generates control voltage signals.
- Power Amplifier：Converts control voltage signals into control current.
- Magnetic Bearing：Generates electromagnetic force to support the rotor.
- Rotor：Maintains a stable levitated and balanced position.
The principle of keeping the rotor stably levitated is that the rotor is suspended under the action of magnetic force. When the rotor is disturbed, the sensor detects the rotor's displacement reference point and sends the displacement signal to the controller. The controller's microprocessor calculates the control signal based on the detected displacement signal. Then, the power amplifier converts the control signal into control current and inputs it to the magnetic bearing. Through the coordination of these components, the magnetic levitation motor can operate stably at high speed without friction.
The fluid components include three-dimensional flow impellers and volutes. The impellers are made of high-strength alloy through five-axis machining as an integrated unit, ensuring sharpness, strength, and reliability. The impellers adopt three-dimensional flow theory and optimized designs of high-efficiency volutes, making the equipment suitable for gas transmission and compression applications across various industrial fields.
The working principle of the 3D impeller is based on the control of dynamic balance and fluid flow during rotation. When fluid enters the inlet of the 3D impeller, the guide vanes regulate its flow direction and velocity. Under the rotational action of the impeller blades, the fluid is compressed and accelerated, eventually exiting through the impeller outlet. Compared with traditional impellers, the 3D impeller offers higher efficiency and a wider range of applications. Its simple structure allows for better control of the fluid's flow direction and velocity, making the compression and acceleration of the fluid more uniform and stable. In practical applications, the use of the 3D impeller can significantly improve the performance and efficiency of equipment while reducing energy consumption and waste.
Multi-physical field design circuit is used in the design of the motor, fully considering the interaction between physical fields. The ultra-efficient permanent magnet synchronous motor is directly connected to the three-dimensional impeller and the cooling fan, ensuring high efficiency and zero transmission loss.
These advantages make the permanent magnet synchronous motor perform well in many application scenarios, especially in situations requiring high-efficiency energy conversion and compact design. Its service life is more than 20 years.
In the operation process of a high-efficiency frequency converter, the alternating current (AC) power source is first rectified into direct current (DC) power. It is then converted back into AC power of different frequencies through an inverter circuit to meet the speed requirements of various electric motors. This adjusts the motor's speed and power output, ensuring the stable operation of the system.
