specific Embodiment approach 1

[0023] Specific Embodiment 1: A long-stroke synchronous planar motor with a unilateral structure and an integrated winding structure described in this embodiment includes an armature component and a permanent magnet excitation component. There is an air gap between the armature component and the permanent magnet excitation component. The armature component includes an armature winding and a winding substrate, and the permanent magnet excitation component includes a permanent magnet array and a flat permanent magnet yoke plate;

[0024] The armature winding is a four-phase winding, and the armature winding is composed of 4m square coils wound in the same direction, and every four coils are arranged into a "field"-shaped unit four-phase winding unit, and four coils in each four-phase winding To form a four-phase winding, the 4m coils form m four-phase windings connected in series or in parallel, all the coils in the armature winding are located on the XY plane, and the coil sides...

Abstract

The invention relates to a long stroke synchronous planar motor with an integrated winding structure, which belongs to the field of motors and solves the problems of complicated structure, low winding use ratio, large loss and limited stroke of the traditional planar motor. The planar motor consists of a plurality of motor units. The width lt of a coil and the polar distance gammap of a permanent magnet array in each motor unit satisfy the relation: lt=gammap; the center distance gammat of the coil and the polar distance gammap of the permanent magnet array satisfy the relation: gammat=1.5 gammap. An armature winding of each motor unit consists of four square coils, the winding directions are same; the coils are fixedly arranged on a flat-shaped winding substrate in Chinese character 'tian'; permanent magnets in the permanent magnet array of each motor unit are evenly distributed on a permanent magnet yoke plate; the magnetizing directions of the permanent magnets, the opposite angles of which are adjacent, are opposite; and the magnetizing directions in the same row or line are same. The planar motor has simple structure, easy control and high control precision, and the stroke is not limited. The planar motor is suitable for being used for 2-D planar drive devices, in particular for precise 2-D planar drive devices.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a long-stroke synchronous planar motor with an integrated winding structure. 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 stru...
