The miniature closed-loop voice coil motor containing rare earth magnetic materials can effectively improve the clarity of mobile phone photos.

Jiangxin Micro Motor Technology Co., Ltd. (hereinafter referred to as Jiangxin Micro Motor) through technical optimization of miniature closed-loop voice coil motors containing rare earth magnetic materials, the consistency and reliability of various functional indicators of the products have been improved, and have been certified by Huawei, Samsung, OPPO, MOTO and other international well-known brands to meet the conditions for entering small batch trial production.

It is reported that compared with the advanced technology of foreign mainstream international manufacturers in camera micro-camera automatic zoom motor (VCM), Jiang Xin micro-motor independently developed a set of intelligent production line of miniature voice coil motor in omni-directional technical cooperation with Dongguan Institute of Optoelectronics of Peking University. It mainly includes the research and development of stator components, moving parts, motor assembly technology, lettering technology, performance testing technology, appearance inspection technology and packaging technology and equipment. To achieve the micro voice coil motor stroke, power consumption, moving tilt angle and fast response time and other indicators to meet the overall performance requirements of the mobile phone. This motor can realize the advantages of intuitive and real mobile phone video images, convenient transmission and practical stereoscopy. the technical level has reached the international leading level, and the market share has increased from 2% to about 5%.

After the implementation of the project of miniature closed-loop voice coil motors containing rare earth magnetic materials, the annual production capacity will reach 12 million units, the sales revenue will increase by 60 million yuan, and nearly 120 new jobs will be created.
