How to select voice coil motor and its advantages

Voice coil motor has the advantages of high response, high speed, high acceleration, simple structure and small volume. It is widely used in many precision positioning systems. At the same time, it is very suitable for short stroke closed-loop servo control system. The following is a detailed introduction. "How to choose a voice coil motor and its advantages"

Ⅰ. How to select voice coil motor

1. It is necessary to clarify whether the voice coil motor is used to provide linear motion or swing motion, because if it is to provide linear motion, it should be selected from cylindrical, flat, rectangular, and shaft voice coil motors. If it is to provide swing motion, it should be selected from the swing type of voice coil motor.

2. For the required use space of voice coil motor, such as cylindrical use space, only cylindrical voice coil motor can be selected, and so on.

3. It is necessary to clarify the relevant parameters of the required voice coil motor, such as stroke, accuracy, load, speed, motion state, whether it is waterproof, etc., because the parameters of each voice coil motor are different.

4. Clarify whether supporting equipment is required. Some customers have not used the voice coil motor. They do not know that they need to be equipped with drivers, encoders, etc. In order to run the voice coil motor, there is only thing customers can do is to just buy motor only. DINGS’ has various solutions to solve out these kinds of difficulty from customers by providing drivers and linear encoder options.

Ⅱ. Advantages of voice coil motor

1. Voice coil motor has the advantages of high response, high speed, high acceleration, simple structure, small volume, good force characteristics, convenient control and so on. In recent years, with the rapid development of voice coil motor technology, voice coil motor is widely used in precision positioning system and many different forms of high acceleration, high-frequency excitation, fast and high-precision positioning motion system.

2. Compared with the slotless linear motor and the slotted linear motor, it can provide better high-frequency response characteristics, can perform high-speed reciprocating linear motion, and is especially suitable for closed-loop servo control systems with short strokes. The control of the voice coil motor is simple and reliable, no commutation device is required, and the product life cycle is long.
