What are the main influencing elements of the coil motor? The coil motor has a long history, but it has only been known to the public in recent years, and it has been able to enter the public eye, thanks in part to the iPhone 6, which was not yet available. Various propaganda channels have reported strongly on the use of coil Motors(coil motors) in their camera modules. Because of this, many fruit fans have specifically studied the sound coil motor(sound coil motor). Now, the small editor has to check the operation. Do the fruit fans know what the main elements that affect the performance of the sound coil motor(sound coil motor) are?
Among them, the elements that affect the performance of the coil motor(coil motor) mainly include the thickness of magnetic steel, the thickness of the external magnetic yoke, the distance between poles, and the length of the stationary element.
1, the influence of the thickness of magnetic steel: the greater the thickness of magnetic steel, the stronger the air gap magnetic field, the greater the output of the motor, but in the condition of the motor's external diameter fixed, the diameter of the ring to reduce. Therefore, it is necessary to select the thickness of magnetic steel properly in order to make the coil motor(coil motor) have a larger output.
2, the influence of the outer track thickness: thick pass small, saturation degree increases, the motor's magnetic leakage will increase; Conversely, the thickness is too large, and the diameter of the ring will decrease. Therefore, the outer magnetic yoke thickness must be reasonably designed.
3, the influence of the distance between the poles: There is a large magnetic leakage between the two ring poles of the ring motor(ring motor). The leakage magnetic field will increase the flux of the external magnetic yoke and increase the saturation degree; In order to reduce the magnetic leakage between the poles, a magnetic separation ring is designed between the poles to reduce the saturation of the outer magnetic yoke part and reduce the thickness of the magnetic yoke. However, the distance between poles must be reasonably designed, otherwise it will affect the total flux of the motor, but instead reduce the output of the coil motor(coil motor). It can be seen that the distance between poles has a more obvious influence on the output of the motor.
4, the influence of stator and mover length: The selection of stator and mover length mainly affects the smoothness of the "force-displacement" curve of the loop motor(loop motor). When the stator length is certain, appropriately changing the moving length can make the "force-displacement" curve smoother, but it should be based on meeting the travel requirements of the coil motor(coil motor). Otherwise, it will cause an increase in the volume of the coil motor(coil motor) and a waste of costs.
