Abstract

The invention discloses a hybrid reluctance type magnetic levitation linear motor with a bypass iron core, which comprises an upper stator, a lower stator and a mover. The upper stator includes a left levitation iron core, a right levitation iron core, side It is regarded as "M" shape, and two axially magnetized permanent magnets are arranged between the teeth of the "M" shape structure, and the inner side of the left and right suspension cores are respectively equipped with a left stator bypass core and a right stator bypass core. The lower stator has the same structure as the upper stator and is set opposite to each other; the levitation control flux generated by the levitation winding and the bias flux generated by the permanent magnet interact to generate a stable radial levitation force on the left and right suction plates, The left and right control cores are provided with control windings, and the control winding wheels are energized to realize the axial linear motion of the mover. A hybrid reluctance type magnetic levitation linear motor with a bypass core realizes the non-contact suspension support of the mover, which greatly improves the sensitivity, quickness and positioning accuracy of the system.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a hybrid reluctance type magnetic levitation linear motor with a bypass iron core, which has no friction and wear, simple control, reliable operation, strong load capacity, fast response speed and accurate positioning. Background technique [0002] With the rapid development of automatic control technology and microcomputers, higher requirements are placed on the positioning accuracy of the linear motion control system. The linear motion drive device composed of a traditional rotating motor and a set of transformation mechanisms has been difficult to meet the requirements of modern linear motion control. The performance requirements of the system, the direct drive of the linear motion load by the linear motor has the following advantages: ①. The structure is simple, because the linear vibration motor does not need additional devices to convert the rotary mo...
