Abstract

The invention discloses a magnetic resistance type multi-DOF (degree of freedom) magnetically-levitated planar motor, which belongs to the technical field of motors, and solves the problem that the existing permanent magnet synchronous planar motor is complicated in structure and low in positioning accuracy. The planar motor is composed of a primary part, a secondary part and air gaps, wherein the primary part is composed of an upper primary plate, a lower primary plate and armatures, and each armature is composed of an armature core, an armature winding and a primary permanent magnet; the secondary part is composed of a secondary base plate and a secondary yoke plate; and the armatures are divided into three or four sets and uniformly and symmetrically distributed at the periphery between the upper primary plate and the lower primary plate, the secondary part is also arranged between the upper primary plate and the lower primary plate, and the air gaps are formed between the upper primary plate and the secondary part and between the secondary part and the lower primary plate. The planar motor disclosed by the invention is applicable to magnetically-levitated planar motors.

Description

technical field [0001] The invention relates to a reluctance type multi-degree-of-freedom magnetic levitation planar motor, which belongs to the technical 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. The original planar driving device was realized by two directly driven linear motors, and a stacked driving structure was adopted. This structu...
