High-efficient electromagnetic drive system

The invention provides a high-efficient electromagnetic drive system. Electromagnets are respectively installed on a fixed body and a moving body. According to the principles that energization of electromagnet coil can produce magnetism and the 'likes repel, opposites attracts' of magnetic pole, the magnetic poles which are opposite to the moving body and the fixed body are adjusted to be opposite, gravitation is produced, and the moving body moves forward. When the electromagnet of the moving body approaches to the electromagnet of the fixed body, power source is cut off, then the direction of current is switched so that the magnetic poles of the moving body and the fixed body are enabled to be consistent and repulsion is produced. After the moving body inertially moves and crosses the central line of the magnetic poles, forward thrust can be obtained again. A set of electromagnets are arranged on the fixed body at certain intervals so that the moving body can continuously move forward along a fixed track. T
