Abstract

The invention relates to a limited stroke high-dynamic plane motor which belongs to the technical field of motors. The invention solves the problems of small stroke and small output thrust of the traditional synchronous short-stroke plane motor. The limited stroke high-dynamic plane motor comprises a motor unit and a rotor support mechanism, wherein the motor unit comprises a motor primary class and a motor secondary class; the motor unit has a short motor primary class and long motor secondary class structure; an air gap is arranged between the motor primary class and the motor secondary class; the motor primary class has an iron core-free structure and comprises a winding fixed support plate and four armature windings; the winding fixed support plate has a lip-rounding structure; each armature winding is correspondingly and centrally fixed on a lip-rounding frame of the fixed support plate, the four armature windings are positioned on the same plane, each armature winding is a symmetrical multiphase winding formed by a group of coils; the effective edge of the coil of each armature winding is perpendicular to the lip-rounding frame of the fixed support plate; and the motor secondary class has a double-edge structure and is symmetrically arranged at both sides of the motor primary class. The limited stroke high-dynamic plane motor is used as a plane motor.

Description

technical field [0001] The invention relates to a limited-stroke high-dynamic 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 complex structure 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 defects. The original planar driving device was realized by using two direct-driven linear motors, which used a stacked driving structure, which increased the complexity...
