The voice coil motor is compared with the rotary motor. The voice coil motor is a special type of direct drive motor that can directly convert electrical energy into linear motion mechanical energy without any intermediate transmission mechanism.
Voice coil motor principle is: in a uniform air gap magnetic field into a cylindrical winding, the windings are energized to generate electromagnetic force to drive the load for linear reciprocating motion, change the strength and polarity of the current, you can change the size and direction of the electromagnetic force . Therefore, the voice coil motor can be in the form of a straight line or a rotation. The utility model has the advantages of high response, high speed, high acceleration, simple structure, small volume, good force characteristics, convenient control and the like. Here we compare the voice coil motor with the rotary motor. The main features are as follows:
1 voice coil motor structure is simple, because the voice coil motor does not need to turn the rotary motion into an additional device, which makes the system itself greatly simplified structure, weight and volume greatly reduced;
2 The positioning accuracy is high. In the place where linear motion is required, the voice coil motor can realize direct transmission, thus eliminating various positioning errors brought by intermediate links. Therefore, the positioning accuracy is high. If the microcomputer control is used, the voice coil motor can be greatly improved. The positioning accuracy of the entire system;
3 voice coil motor response speed, high sensitivity, good follow-up. The voice coil motor is easily supported by the magnetic levitation of its mover, so that there is always a certain air gap between the mover and the stator without contact, which eliminates the contact frictional resistance between the stator and the mover, thereby greatly improving the System sensitivity, rapidity and follow-up;
4 voice coil motor work safe and reliable, long life. The voice coil motor can realize the non-contact transmission force, and the mechanical friction loss is almost zero, so the failure is less and maintenance-free, so the work is safe and reliable, and the service life is long.
Tongmao voice coil motors use high-efficiency ironless linear motors as drive components. Our direct drive platform has high speed, high acceleration and stable accuracy. Compared with the screw drive, the structure is more compact and more efficient. Single-axis voice coil motors provide satisfactory system solutions for applications that require high throughput, high reliability, precision positioning, and silent operation.
