Abstract

The invention relates to a magnetic suspension flat motor with a primary structure on both sides, which belongs to the technical field of motor and solves the problems of the existing permanent magnetic synchronous flat motor, such as complex structure and low location accuracy. The flat motor consists of a horizontal force output motor unit, a Z-direction force output motor unit, a primary upper substrate, a primary lower substrate and a secondary substrate, wherein the horizontal force output motor unit is mainly composed of an upper primary, a lower primary, a secondary and an air gap; and the Z-direction force output motor unit is mainly composed of an upper primary, a lower primary, a secondary and an air gap. The invention is applicable to the magnetic suspension flat motor.

Description

technical field [0001] The invention relates to a bilateral primary structure 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 structure increased...
