The utility model aims at providing an electromagnetic vertical lifting device with high speed and energy conservation, which fundamentally solves the lifting problem of high-rise buildings, and the utility model aims at realizing the electromagnetic vertical lifting device, which comprises a frequency conversion cabinet, a permanent magnet coil, a mobile power receiver, a rotary encoder, a power coil, a mobile power line, a sliding power collector, a car door and a well, wherein the permanent magnet coil is arranged in a slide way from top to bottom, the top end in the permanent magnet coil is provided with the mobile power receiver, and the mobile power receiver is connected with a power supply by a power line; the frequency conversion cabinet is connected with the mobile power receiver and is arranged on the top surface of the lift car; the upper end of the lift car is provided with a rotary encoder, and the lower side of the rotary encoder is provided with a power coil; the rotary encoder is connected with the sliding power supply collector; the car door is connected with the rotary encoder and the sliding power supply collector through a circuit.

The application method of the utility model is that the principle of the magnetic suspension train is utilized to erect the magnetic suspension train, and the object is suspended and kept still in the half-empty state mainly by utilizing the attraction and repulsion of the magnet; the novel magnetic suspension elevator has frequency conversion strong magnetism in the car supporting beam, and is comprehensively adjusted through magnetic interaction with an electromagnetic coil on an electromagnetic guide rail when moving, so that the car and the guide rail are in zero contact. Because of no friction, the magnetic suspension elevator is quite quiet and more comfortable when in operation, and can reach the extremely high speed which can not be reached by the traditional elevator. The elevator is suitable for the vertical transportation equipment for people and goods, such as the building elevator, the launching platform, the space elevator and the like. The elevator is very energy-saving. According to the electromagnetic induction principle, kinetic energy and potential energy of the car can be recovered in a mode of cutting magnetic induction lines by using an electromagnetic guide rail, so that the energy consumption of the car is greatly reduced; its average speed can reach more than 300 meters per minute, which is 3 times of the speed of a common elevator (average 100 meters per minute).
