Embodiment Construction

[0019] see figure 1 and figure 2 , the disc voice coil motor 1 of the present invention includes a stator 10 that can be installed on a fixed support body, and a mover 20 that is installed corresponding to the stator 10 and can move relative to the stator 10 .

[0020] see image 3 , the stator 10 includes a stator yoke 11 , a coil 12 , a wire cover 13 and a cooling plate 14 . The stator yoke 11 is disc-shaped. The stator yoke 11 is provided with a circular cooling pipe 111 . The cooling plate 14 is installed on the stator yoke 11 so that the cooling pipe 111 forms a sealed pipe for the circulation of cooling liquid. The coil 12 generally has a fan-shaped ring structure. The wire cover 13 is also disc-shaped, and its inner and outer sides protrude to one side respectively to form a snap ring 131 and an outer side wall 133. There are several engaging grooves 132 , the surface shape of the engaging grooves 132 is adapted to the shape of one end surface of the coil 12 , and ...

Abstract

The invention discloses a disc-typed voice circle motor, comprising a stator, and a rotor which moves correspondingly to the stator; the stator comprises a stator yoke, a coil and a wire cover; the rotor comprises a rotor yoke and a magnet; wherein, the coil is a sector ring-shaped structure and the magnet is a sector shape. The disc-typed voice ring motor adopts the stator and the rotor without iron cores, leads the coil to be designed as a sector ring-shaped structure, and leads the magnet to be designed as a sector structure; therefore, the preparation process is simple, the natural harmonic moment can be effectively reduced, and the precision of the disc-typed voice coil motor is improved.

Description

【Technical field】 [0001] The invention relates to a motor, in particular to a disc voice coil motor. 【technical background】 [0002] With the development of modern industry, voice coil motors have been more and more widely used due to their unique characteristics of high response, high acceleration, high speed and small size. [0003] Traditional finite angular torque motors mostly use armature rotors or stators with iron cores, and the windings are distributed wave or stacked structures. However, in addition to the complex manufacturing process of this structure, the inherent harmonic torque hinders the application of torque motors in precision motion systems and direct drive systems. [0004] Therefore, how to provide a voice coil motor that has a simple manufacturing process and can effectively reduce the inherent harmonic torque has become an urgent problem to be solved. 【Content of invention】 [0005] The technical problem to be solved by the present invention is to...
