The linear motor is a novel motor. The combination of magnetic levitation and linear motors has led to new technologies, such as magnetic levitation trains and production conveyor lines. A linear motor, primarily a linear electric motor, is a transmission device that converts electrical energy directly into mechanical energy for linear motion without any intermediate conversion mechanism. It emerged in the second half of the 20th century as a new technology in the field of electrical engineering, incorporating novel principles and theories. Its distinctive advantages have increasingly attracted attention.
The advantages of magnetic levitation motors include:
1. Non-contact operation, zero friction and wear, significantly reduced vibration and noise, and long lifespan;
2. Applications in specialized applications, such as vacuum, high and low temperatures, water vapor, and within living organisms, without damaging the original body;
3. Applications requiring control, such as position, overspeed, and vibration, are relatively easy to control;
4. Applications in specialized applications, such as memory, learning, and judgment, as well as the ability to monitor, record, and diagnose operating conditions;
5. Applications requiring distributed control of forces, such as the distribution and control of force at various points in magnetic levitation vehicles and magnetic bearings. The main future development trends of magnetic levitation
Motors are as follows:
1. DSP-based control is gaining wider application in magnetic levitation technology;
2. Permanent magnets and superconducting materials are gaining further application in magnetic levitation technology;
3. Control theories such as multivariable control are driving the development of magnetic levitation technology;
4. The widespread adoption 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 are all placing greater demands on magnetic levitation technology.
