Application advantages and development trends of magnetic levitation motors
Linear motors are a novel type of motor. The combination of magnetic levitation and linear motors has led to some new technologies, such as magnetic levitation trains and production conveyor lines. Linear motors are mainly linear electric motors, which are transmission devices that directly convert electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It is a new technology with new principles and theories in the field of electrical engineering in the second half of the 20th century. Its outstanding advantages have attracted more and more attention.
The application advantages of magnetic levitation motors are:
- Non-contact application, no friction, wear, vibration and noise are greatly reduced, and the service life is long;
- Application in special occasions, such as vacuum, high temperature, low temperature, water vapor, biological body and other special applications, without damaging the original body;
- Application in occasions that need to be controlled, such as position, overspeed, vibration, etc., which are relatively easy to control;
- It has some special occasions: such as memory, learning, judgment ability, monitoring, recording, and diagnosis of operating status;
- Distributed application of controllable force: such as the distribution and control of position force at each point of magnetic levitation vehicles and magnetic levitation bearings.
The future development trends of magnetic levitation motors are mainly as follows: - DSP-based control magnetic levitation technology has been more widely used;
- Permanent magnetic materials and superconducting materials have been further applied in magnetic levitation technology;
- Control theories such as multivariable control have promoted the development of magnetic levitation technology;
- The development and popularization of computers, large-scale integrated circuits, the development of new materials, the development of space, the sophistication and diversification of technology, and energy conservation and environmental protection have all put forward requirements for magnetic levitation technology.
