1, buy a single voice coil motor or buy voice coil motor module? I think if you know a lot about voice coil motor, you can go back and build your own structure, you can buy a single voice coil motor; if you don't know a lot about voice coil motor, I hope you can buy it and use it directly, avoid worry, you can buy voice coil motor module.

     2. Some voice coil motors have holes or no holes in the motor, What's the difference? In fact, there is no big difference between the hole, which is the special process requirements of some customers.

      3.Where is the mounting surface of voice coil motor? The base of voice coil motor stator and the top of the rotor are mounting surfaces. 

      4. What about the parameters of voice coil motor? Many customers ask the voice coil motor how much frequency can be achieved, etc. . In fact, the parameters involved in the voice coil motor, such as load, travel, frequency, etc. , are mutually restrained, and there is no exact value, it needs to be evaluated in combination with all the parameters. 

     5, voice coil motor repeat positioning accuracy can achieve how much? Voice coil motor itself is not involved in the repeated positioning accuracy of this parameter, this parameter is closely related to the voice coil motor module encoder. 

      6, voice coil motor driver how to choose? First, the current and voltage supported by the driver need to match the current and voltage of the motor, and second, the need to see the customer needs of the upper-level communication mode, is the support pulse, or Canopen + Modbus, or EtherCAT, etc. .
