From smart phone cameras, automatic driving car cameras to automatic feeding systems, voice coil motors are widely used in many industrial fields and the market scale has grown significantly.
Recently, ZJXS Micro Motor Technology Corporation, which is engaged in the design, development, production, manufacturing and sales of micro auto focusing voice coil motor and piezoelectric motor, was awarded as the invisible champion in China's micro AF-VCM field.
Voice coil motor (VCM) is one of the core components of the camera module, which plays the role of carrying the lens and adjusting the lens position in the camera module to achieve automatic focusing and optical anti shake.
Among them, the basic principle of the former is to use the relationship between image distance, object distance and focal length to realize automatic focusing by moving the lens group through VCM;
The basic principle of the latter is that in the shooting process, when the gyroscope in the lens detects a small movement, it transmits the signal to the mobile phone microprocessor and calculates the compensation displacement, and then compensates through VCM to reduce the imaging offset.
In recent years, thanks to the rapid growth of the smartphone market, the global VCM market has also grown rapidly. According to QY Research, China is currently the world's largest voice coil motor market, with a market share of more than 54%.
At the same time, more than 80% of the global VCM market share is occupied by five major manufacturers, and ZJXS of China is one of them.
ZJXS is committed to the design, R&D, manufacturing and sales of micro voice coil motor with auto focus function built in handheld devices. It is the industry pioneer of auto focus voice coil motor, and has successively designed and developed products such as wind motor, linear motor, vibration motor and zoom motor.
The products are widely used in mobile phones, computers, automobiles and other products. They have a prominent advantage in multi lens modules, and the technical race has been in a leading position.
the company is the world's largest manufacturer of mini AF VCMs and piezoelectric motors with extrodinary and flexible VCM assembly capability. As i t is achieving fully automatic production, the New ZJXS has become the largest domestic motor manufacturer.
It is one of the major motor suppliers of module factories such as OFILM, Q Technology, Sunny Optical Technology, Luxvisions, Holitech, TXD and PRIMAX and the main suppliers of Huawei, MI, Vivo, OPPO, Lenovo, LG, Huaqin, Wingtech, Longqi and other terminals as well.
ZJXS has completed the development of new products: ball bearing motors and 3.4mm ultra micro motors.
The whole series of ball bearing motors will use ceramic balls, which can improve the motor life in an all-round way. The service life of its spring fragments will exceed 15 million rebounds. In addition, the combination of ball+spring fragments+low-temperature grease can achieve a starting voltage of 1.8V at minus 40 ℃.
3.4 mm subminiature motor is committed to becoming the smallest and lightest subminiature motor in the world. The whole system will use the skeleton and magnetic pole to form in one, maintain stable performance, and aim to achieve the highest torque measured value in the world within the same size space.
