Abstract

The invention discloses a linear induction repulsion buoyancy motor comprising a mover core, a stator base, a stator winding, a suspended permanent-magnet and an excitation winding. The stator winding is arranged at the upper end of the stator base and drives the mover core to rotate; the suspended permanent-magnet and the excitation winding are arranged oppositely, wherein, the suspended permanent-magnet is arranged on a mover; the excitation winding is arranged on the stator base; the suspended permanent-magnet is an array permanent-magnet that is arranged horizontally and vertically; and the magnetic density of the suspended permanent-magnet on the side opposite to a magnetic winding is stronger than that of the other side of the permanent-magnet. In the linear induction repulsion buoyancy motor, the Halbach array permanent-magnet is installed on the mover, the repulsion buoyancy is formed by the array permanent-magnet and the excitation winding on the stator base during the moving process, so the mover suspends with no contact and no friction, and can run at a high speed under the action of traction force. By adopting a unilateral primary linear induction motor, the invention solves the problem that a moving part is not easy to supply the electrical source in magnetic suspension launch.

Description

technical field [0001] The invention belongs to a novel device of a linear motor. This technology can be applied to the technical fields of high-speed trains, numerical control machine tools, and maglev launching. The core of this technology is to use Halbach permanent magnets and short-circuit coils to generate repulsive buoyancy, so that the stator and moving parts have no contact, no friction, and the operation process is safe and controllable. The principle of single-sided linear induction motor is used to provide traction thrust. Background technique [0002] Maglev launches and high-speed maglev trains are applications of linear motors. When high-speed maglev trains and maglev launches are running, they rely on electromagnetic attraction or electric repulsion to suspend the car body in the air without mechanical contact with the track, and rely on the electromagnetic thrust generated by the linear motor to realize the train. traction. They attract more and more atte...
