Abstract
The invention relates to a cylindrical permanent-magnet voice coil motor. The cylindrical permanent-magnet voice coil motor comprises a movable shaft, a permanent magnet, an excitation coil, a stator sleeve, a left block plate, a right block plate and an insulation tube, wherein the stator sleeve is a stator sleeve without a notch in the inner surface, the outer circle of the excitation coil and the inner circle of the stator sleeve are in interference fit, the insulation tube is arranged in the center of the excitation coil, the excitation coil and the outer circle of the insulation tube are cured into a whole, the inner circle of the insulation tube and a forcer are in clearance fit, the difference between the length of the forcer and the length of the excitation coil is motion displacement of the motor, and the left block plate and the right block plate are fixed at the two sides of the stator sleeve so as to axially fix the excitation coil. In the cylindrical permanent-magnet voice coil motor, the permanent magnet is arranged on the movable shaft to form the forcer, the excitation coil with large volume is arranged in the stator sleeve in an interference fit manner, the stator sleeve adopts a structure without the notch, and thus, embedding operation of the excitation coil is avoided. The whole structure is low in forcer loss and is simple, volume is reduced, and long-distance linear motion of the motor is promoted.

Technical background
At present, column type permanent-magnet voice coil motor has high frequency sound, high-precision feature because of it, has been widely used in the fields such as medical treatment, semiconductor, aviation, automobile.Existing column type permanent-magnet voice coil motor is made up of stator and mover, stator is equipped with permanent magnet, mover is wound with magnet exciting coil, and mover is when moving, and its supply lines can be drag and move together, therefore can not realize the linear reciprocating motion of long distance.Mover adopts electric excited work mode, needs to be wound around magnet exciting coil on mover, directly causes mover volume to become large, structure complicates, and operation stability is not high, and when mover electricity excitation, before mover rectilinear motion, there will be suspension action, cause bumpy motion.
Summary of the invention
The object of the invention is to overcome above defect, provide a kind of can realize stable long distance rectilinear motion and structure is simple, stable movement column type permanent-magnet voice coil motor.
Technical scheme of the present invention is: a kind of column type permanent-magnet voice coil motor, it comprises kinematic axis, permanent magnet, magnet exciting coil, stator sleeve, right baffle-plate, right baffle plate, insulated tube, the cylindrical that described permanent magnet is arranged on kinematic axis forms mover, described magnet exciting coil is located in stator sleeve inner circle, described stator sleeve is the stator sleeve of inner surface without notch, the cylindrical of magnet exciting coil and stator sleeve inner circle are interference fit, insulated tube is arranged on the central interior of magnet exciting coil and magnet exciting coil and insulated tube cylindrical solidify as a whole, the inner circle of described insulated tube and mover are matched in clearance, the difference of the length of mover and the length of magnet exciting coil is the movement travel of motor, right baffle-plate and right baffle plate are fixed on the both sides of stator sleeve from axial restraint magnet exciting coil.
In order to the resultant field of realizing ideal, described permanent magnet adopts axial charging, and the arrangement of adjacent permanent magnet on kinematic axis is N pole and N pole, S pole and S pole arranged opposite.
In order to be beneficial to axially loaded, described right baffle plate and stator sleeve as a whole.
In order to be beneficial to the stronger excitation field of generation and be beneficial to the inlet wire of magnet exciting coil and outlet in the same side, described magnet exciting coil is the telescopic coil of even level helical form.
Preferably, the number of plies of described magnet exciting coil is 2 layers.
Preferably, the number of plies of described magnet exciting coil is 4 layers.
Preferably, the number of plies of described magnet exciting coil is 6 layers.
Operating steadily to be beneficial to, also comprising sliding bearing, described sliding bearing arranges the position being separately positioned on right baffle-plate and contacting with mover with right baffle plate.
The invention has the beneficial effects as follows: form mover owing to being arranged on kinematic axis by permanent magnet, and be interference fitted in stator sleeve by magnet exciting coil larger for volume, stator sleeve adopts without notch arrangement, avoids the rule operation of magnet exciting coil; The loss of total mover reduces, and volume reduces, and structure is simple, is beneficial to the rectilinear motion that motor realizes long distance.Particularly magnet exciting coil adopts even level helical form telescoping structure, is beneficial to the induced field that generation is stronger, raises the efficiency, and is beneficial to magnet exciting coil lead-out wire and is distributed in the same side; In addition, owing to adopting sliding bearing, avoid the suspension action of mover during electric motor starting, improve traveling comfort.
