Abstract

The invention relates to a magnetic suspension planar motor with a superconductor excitation structure, belongs to the technical field of motors and solves the problems of complicated structure, large planer movement scope, low winding utilization efficiency, small reasoning density and low system efficiency existing in the existing permanent magnet synchronous planar motor. In the magnetic suspension planar motor, a primary substrate is flat plate-shaped; an armature winding is fixedly arranged at the air gap side of the primary substrate; a secondary substrate is uniformly divided into 2h*2h magnet cells; 2h<2> superconducting magnets are respectively and fixedly arranged in the superconducting magnet cells adjacent at opposite angles on the secondary substrate and are not adjacent parallelly and vertically; the superconducting magnets are magnetized in parallel, the magnetizing directions of the superconducting magnets are vertical to a surface at the air gap side of the secondary substrate; the magnetizing directions of the superconducting magnets positioned on the same line or row are identical; the magnetizing directions of the superconducting magnets positioned on adjacent lines or rows are opposite; and a cooling container is covered outside all the superconducting magnets. The magnetic suspension planar motor has the beneficial effects that the primary suspension motion is realized, the suspension height is large, the bearing capacity is strong, and the magnetic suspension planar motor can be applied to the vacuum environment.

Description

technical field [0001] The invention relates to a magnetic levitation planar motor, which belongs to the field of motors. Background technique [0002] Modern precision and ultra-precision processing equipment has an urgent need for high-response, high-speed, high-precision planar drive devices, such as machining, electronic product production, mechanical loading and unloading, manufacturing automated instrumentation equipment, and even robot drives. Usually these devices are powered by a rotary motor, and then converted into linear motion by mechanical devices such as belts and ball screws. Due to the complexity of the mechanical device, the transmission accuracy and speed are limited, and frequent adjustments are required, resulting in high cost, poor reliability, and large volume. [0003] The original planar driving device was realized by two directly driven linear motors, and a stacked driving structure was adopted. This structure increased the complexity of the transm...
