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]
The present invention relates to a kind of motor, relate in particular to a kind of disc type voice coil motor.
[technical background]
Along with development of modern industry, voice coil motor has obtained application more and more widely in line with its distinctive high response, high acceleration, high-speed, characteristics that volume is little.
Finite angle torque motor traditionally adopts the armature rotor or the stator of ribbon core more, and winding is distributed wave mode or folded type structure.Yet this structure is except that the manufacturing process complexity, and intrinsic harmonic wave moment has hindered the application of torque motor in precision kinematic system and Direct Driving System.
Therefore, how to provide a kind of manufacturing process voice coil motor simple and that can effectively reduce intrinsic harmonic wave moment to become current urgent problem.
[summary of the invention]
It is simple and can effectively reduce the voice coil motor of intrinsic harmonic wave moment that the technical problem that institute of the present invention desire solves provides a kind of manufacturing process.
The technical solution adopted in the present invention is: a kind of disc type voice coil motor, comprise the mover that stator, relative stator are moved, and this stator comprises stator yoke, coil and line lid, this mover comprises mover yoke and magnet, wherein, described coil is the fan-shaped ring structure, and described magnet is fan-shaped.
Described stator also comprises coldplate, and described stator yoke is provided with belt cooling pipe, and coldplate is installed on the stator yoke.
Described stator yoke is disc, its inside and outside disc edge is convexly equipped with to a side and forms engaging circle, lateral wall, and described engaging circle outwards is provided with some slots, and described coil is installed between this slot and lateral wall, some described coil arrangement form the winding of a disk shape together
Be provided with temperature inductor between the described coil.
Described mover yoke is disc, is interval with some projectioies on it, forms receiving space between projection, and described magnet pasting is in described receiving space, and some described magnet form the dish type array.
Described coil, line lid, stator yoke and coldplate are installed on together with the epoxide resin vacuum perfusion.
Described mover yoke is made by high permeability material.
The technique effect that the present invention reached is: disc type voice coil motor of the present invention is by adopting above-mentioned aircored stator and mover, and make coil design become the fan-shaped ring structure, magnet is designed to sector structure, make that not only its manufacturing process is simple, and can effectively reduce intrinsic harmonic wave moment, improve the precision of this disc type voice coil motor.
