音圈电机作为柔性振动盘的核心执行元件，其品质直接影响到整个振动系统的性能。本文旨在分享如何辨别音圈电机品质的关键因素，帮助您选择高品质的音圈电机。以下六个方面为音圈电机品质的主要考量标准：
一、外观品质
表面处理：表面处理是音圈电机外观品质的重要体现，优质的表面处理不仅具有美观的效果，还能提高产品的耐磨性、抗腐蚀性以及抗氧化性。常见的表面处理方法有阳极氧化、电镀、喷涂等。
倒角匀称性：倒角是指在金属工件的边缘或孔口周围，以一定的角度去掉棱角，使其呈斜面状。倒角的主要作用是防止切割、刮伤、磨损等现象，提高产品的使用寿命。倒角匀称性则是指各个边缘的倒角形状和大小一致，这一点对于音圈电机的品质至关重要。
表面无瑕疵：优质音圈电机在生产过程中，应严格控制表面瑕疵。例如，产品表面不能有划痕、气泡、凹陷等现象，以确保音圈电机外观品质达到最佳状态。
二、绕线密度均匀性
音圈电机绕线密度的均匀性直接影响到产品的性能。JKTECH音圈电机通过自研高精度绕线机制作，能够实现线圈排列整齐且无错圈。此外，要观察线圈绕线的密度均匀性，需要对电机进行拆解。
三、漆包线与磁铁品质
漆包线品质：漆包线是音圈电机的关键部件，其品质直接决定了音圈电机的性能。高温漆包线容易发热导致动力衰减，而柔性供料器在大部分场合无需连续运行，因此很多厂家可能忽视漆包线的品质。然而，JKTECH始终坚持使用高品质漆包线，确保音圈电机的持久性能。
磁铁品质：磁铁品质对音圈电机的性能至关重要。耐高温钐钴强磁铁与高品质漆包线的组合，使JKTECH音圈电机在连续高强度运行中不受高温影响。此外，JKTECH对音圈电机进行热力学分析，确保散热效果达到最佳。因此，JKTECH音圈电机非常适用于电子消费产品的振动测试。
四、尺寸精度
音圈电机的尺寸精度是评价其品质的一个重要标准。JKTECH音圈电机整体装配高度精度达到±0.05mm。若精度低于此标准，将导致柔性振动盘整体平面度难以达到±0.1mm，进而影响振动系统的性能。因此，在选择音圈电机时，应特别关注产品的尺寸精度。
五、铝制弹簧材质
音圈电机的铝制弹簧材质对振动盘的平面度和承重能力具有显著影响。一般的音圈电机铝制弹簧使用6061硬质合金铝，而JKTECH音圈电机铝制弹簧采用7075硬质合金铝。相较于6061硬质合金铝，7075硬质合金铝具有更高的强度和回弹能力，能确保柔性振动盘的高平面度和承重能力。
六、音圈电机的电压和振幅推力参数也是重要的指标，工业用的音圈电机一般使用DC24V驱动，参数建议：30电机推力达到0.4KG 振幅达到±1.1mm；55电机推力达到1.2KG 振幅达到±2.5mm.
总结
在选择音圈电机时，要从外观品质、绕线密度均匀性、漆包线与磁铁品质、尺寸精度和铝制弹簧材质等方面综合考虑。了解并掌握这些评价标准，有助于您选购到高品质的音圈电机，从而提高振动系统的性能和使用寿命。

Voice coil motor, as the core actuator of a flexible vibration disc, directly impacts the performance of the entire vibration system. This article aims to share key factors in identifying the quality of voice coil motors and help you choose high-quality ones. The following five aspects are the main considerations for voice coil motor quality:
Exterior Quality Surface Treatment: The surface treatment is a significant reflection of the voice coil motor's exterior quality. High-quality surface treatment not only enhances aesthetics but also improves product wear resistance, corrosion resistance, and oxidation resistance. Common surface treatment methods include anodizing, plating, and coating. Uniform Chamfering: Chamfering refers to the removal of sharp edges at the edges or around holes of metal components, creating inclined surfaces. Chamfering prevents cutting, scraping, and wear, thereby increasing the product's lifespan. The uniformity of chamfering is crucial for the quality of voice coil motors. Flawless Surface: High-quality voice coil motors strictly control surface defects during the production process. For instance, the product surface should be free from scratches, bubbles, and dents to ensure optimal exterior quality.
Uniform Winding Density The uniformity of winding density directly affects the performance of the product. JKTECH voice coil motors are made using a self-developed high-precision winding mechanism, ensuring neat coil arrangement without errors. Disassembling the motor allows for observing the uniformity of coil winding density.
Enamel Wire and Magnet Quality Enamel Wire Quality: Enamel wire is a crucial component of voice coil motors, as its quality directly determines motor performance. High-temperature enamel wire can generate heat, leading to power attenuation. However, many manufacturers may overlook the quality of enamel wire since flexible feeding systems typically don't require continuous operation. Nonetheless, JKTECH always insists on using high-quality enamel wire to ensure long-lasting motor performance. Magnet Quality: Magnet quality is vital for the performance of voice coil motors. JKTECH voice coil motors use high-temperature resistant samarium-cobalt magnets combined with high-quality enamel wire. This combination enables JKTECH voice coil motors to withstand high temperatures during continuous high-intensity operation. Additionally, JKTECH conducts thermodynamic analysis to ensure optimal heat dissipation. Therefore, JKTECH voice coil motors are well-suited for vibration testing in electronic consumer products.
Dimensional Accuracy The dimensional accuracy of voice coil motors is an important criterion for assessing their quality. JKTECH voice coil motors achieve a high overall assembly precision of ±0.05mm. If the accuracy falls below this standard, it would be challenging to achieve ±0.1mm flatness for the entire flexible vibration disc, thereby affecting the performance of the vibration system. Hence, special attention should be given to dimensional accuracy when selecting voice coil motors.
Aluminum Spring Material The aluminum spring material of voice coil motors significantly affects the flatness and load-bearing capacity of the vibration disc. Conventional voice coil motors use 6061 hard alloy aluminum for the aluminum spring, whereas JKTECH voice coil motors adopt 7075 hard alloy aluminum. Compared to 6061 hard alloy aluminum, 7075 hard alloy aluminum offers higher strength and resilience, ensuring high flatness and load-bearing capacity of the flexible vibration disc.
Voltage and Amplitude Thrust Parameters Voltage and amplitude thrust parameters of voice coil motors are also important indicators. Industrial voice coil motors typically use DC 24V drive. Recommended parameters are: for a 30 motor, thrust reaches 0.4KG, and amplitude reaches ±1.1mm; for a 55 motor, thrust reaches 1.2KG, and amplitude reaches ±2.5mm.
In summary, when choosing voice coil motors, it is essential to consider the overall quality from aspects such as exterior quality, uniform winding density, enamel wire and magnet quality, dimensional accuracy, and aluminum spring material. Understanding and mastering these evaluation criteria will help you purchase high-quality voice coil motors, thereby improving the performance and lifespan of your vibration system.
To further explain the importance of these five aspects, we will provide a detailed explanation of the working principle and application areas of voice coil motors.
Working Principle of Voice Coil Motors Voice coil motors are motors that use electromagnetic induction to drive vibrations. When electric current is applied, the voice coil generates a magnetic field that interacts with the magnetic field produced by the magnet, resulting in a torque that drives the vibration disc to move in a linear or rotational motion. The working performance of voice coil motors is closely related to their internal structure, so strict control of the quality of various key components is necessary during the design and manufacturing process.
Application Areas of Voice Coil Motors Voice coil motors are widely used in various vibration devices, such as vibration screens, vibratory feeders, and vibration conveyors. They play a significant role in the following areas:
Vibration Testing of Electronic Consumer Products: Electronic products like mobile phones, tablets, and laptops undergo vibration testing during the production process to ensure product performance and durability. High-quality voice coil motors provide stable and reliable vibration output, meeting the stringent testing requirements of electronic products.
Aerospace Industry: During the development stage of spacecraft and aircraft, vibration environmental tests are conducted on various components to simulate the vibration conditions they may encounter in actual operating environments. High-performance voice coil motors play a crucial role in ensuring the accuracy of test results.
Automotive Industry: Automotive components undergo vibration tests during the production process to evaluate their durability and reliability. Voice coil motors play an important role in vibration test benches, providing precise vibration environments for various automotive components.
Chemical and Pharmaceutical Industries: Vibration equipment is relied upon for processes such as material sieving, conveying, and feeding in chemical and pharmaceutical production. High-quality voice coil motors deliver stable vibration output, ensuring smooth production processes.
In conclusion, voice coil motors have extensive applications in various industries. Selecting high-quality voice coil motors is crucial to ensure the performance and lifespan of vibration systems.
We hope that the five aspects discussed in this article regarding voice coil motor quality identification will help you make informed decisions when purchasing voice coil motors.
