As is well known, installation methods, load (thrust), stroke, and frequency are important parameters of voice coil. In fact, these parameters are closely related and cannot be evaluated independently. So, what is the relationship between the thrust and stroke of a voice coil motor?

    Agnetic field strength: The thrust of a voice coil motor is related to the magnetic field strength. Generally speaking, the stronger the magnetic field, the greater the thrust However, the magnetic field strength is not infinitely increasing, as it is limited by the material of the magnet and the structure of the voice coil motor. Current intensity The thrust of a voice coil motor is also related to the current intensity through the coil. The greater the current intensity, the greater the thrust. However, the intensity cannot be infinitely increased, as it is limited by the coil material, heat dissipation capability, and power supply capability. 

    Voice coil motor structure: The structure a voice coil motor can also affect the relationship between thrust and working stroke. For example, the size of the air gap, the number of turns in the coil and the size of the magnet in a voice coil motor can all affect the magnitude of the thrust and the range of the working stroke. 

    Working stroke: The working of a voice coil motor refers to the peak distance that the voice coil motor can move under normal working conditions. The size of the working stroke affects the magnitude of thrust because, at different working strokes, the magnetic circuit and current path of the voice coil motor change, thus affecting the magnitude of the thrust. 

     Kunshanmao Electronics Co., Ltd. has been engaged in the research, intelligent manufacturing, and sales of voice coil motors for more than ten years. To date,mao has launched hundreds of standard models of voice coil motors in five major categories. Additionally, we can also customize according to customer needs.
