Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a reluctance-suppressed motor winding bobbin, which can avoid the magnetic field force that occurs when the winding bobbin in the existing linear voice coil motor moves relative to each other, and hinders the movement of the winding bobbin in the motor stator In order to avoid the problem of slow response speed and low system flexibility when the linear voice coil motor is running; at the same time, the metal winding skeleton can also ensure the mechanical strength and size requirements of the linear voice coil motor

Embodiment 1

[0029] combine figure 1 and figure 2 , the structure of the motor winding skeleton described in the present invention will be described in detail. The winding skeleton includes a cylindrical body 11. Preferably, the material of the body 11 is any one of aluminum alloy, magnesium aluminum alloy and titanium alloy, which have the advantages of light weight and high mechanical strength. When the winding skeleton moves along the motor stator 2 with high frequency and fast linear motion, it can provide sufficient supporting force and tensile and torsional strength. On the top surface of the main body 11 there is an upper cover 12 for position-limiting function, and on the upper plane of the upper cover 12, a terminal post 13 is installed. On the outer surface of the body 11, there are four baffles 111 arranged around the body 11 and arranged axially. The baffles 111 are a certain distance above the side of the body 11. The blocking pieces 111 respectively form two winding slots...

Embodiment 2

[0033] The present invention also provides another embodiment of the linear voice coil motor, which differs from Embodiment 1 in that the annular structure formed by splicing a plurality of dispersed magnetic tiles 222 is replaced by a single annular structure magnetic tile, and the two The above-mentioned single ring-shaped magnetic tile is connected to the outer yoke body 21 through an aluminum ring 221 , and a pressure ring 223 is installed on the top of the upper single ring-shaped magnetic tile. Using the above solution can greatly reduce the difficulty of processing and assembly, and make the overall structure of the linear voice coil motor simpler, thereby effectively reducing the failure rate and solving the problem of cumbersome replacement and maintenance caused by the damage of the dispersed magnetic tile 222 .

Abstract

The invention relates to the technical field of the small motor manufacturing, and specifically relates to a reluctance suppression type motor winding skeleton and a linear voice coil motor. The winding skeleton comprises a body and an upper cover in fixed connection; the body is made of metal, and a through hole penetrating the interior is formed in the body, a cut slot is formed on the body along a through hole axial direction, and the length of the cut slot is greater than the motion displacement of an active cell in the linear voice coil motor. The motor comprises a motor active cell formed by winding coil on the winding skeleton, and further comprises an outer magnet, an outer yoke and an inner yoke; the outer yoke is coated on the outer surface of the outer magnet, the inner yoke isfixedly arranged in the outer magnet, and the motor active cell can be inserted into the gap between the outer magnet and the inner yoke and can reciprocate in the gap. Through the above structure, the movement resistance on the motor active cell is greatly reduced, the response speed of the voice coil motor in the running is effectively improved, and the system flexibility is improved; and meanwhile, the mechanical strength and the size requirement needed by the linear voice coil motor are guaranteed by the winding skeleton made of the metal material.

Description

technical field [0001] The invention relates to the technical field of small motor manufacturing, in particular to a reluctance suppressed motor winding frame and a linear voice coil motor. Background technique [0002] Voice coil motor (Voice Coil Motor) is a special form of direct drive motor. It has the characteristics of simple structure, small size, high speed, high acceleration and fast response. Its working principle is that when an energized coil (conductor) is placed in a magnetic field, a force is generated, and the magnitude of the force is proportional to the current applied to the coil. The motion form of the voice coil motor manufactured based on this principle can be straight line or circular arc. In recent years, with the improvement of performance requirements for high-speed and high-precision positioning systems and the rapid development of voice coil motor technology, voice coil motors are not only widely used in precision positioning systems such as mag...
