Sound coil motor is a special type of direct drive motor that can directly convert electrical energy into linear motion mechanical energy without the need for any intermediate conversion mechanism. The principle is: In the uniform air gap magnetic field, a cylindrical winding is placed, and the electromagnetic force generated by the winding power drives the load to reciprocate in a straight line. Changing the strength and polarity of the current can change the size and direction of the electromagnetic force. Therefore, the sound coil motor can move in a straight line or rotate. It has the advantages of high response, high speed, high acceleration, simple structure, small size, good force characteristics, and convenient control.
Sound motor can be divided into two types according to the operation mode: linear type and swing type;
According to the appearance structure can be divided into: cylindrical, rectangular, flat, round(including arc) four categories;
Cylinder coil motor
Cylinder coil motors are widely used because they provide high thrust and high speed. This type of motor can generate strong power of 0.7 N ~ 2500 N, so it occupies 80 % or more of the market, and its journey usually does not exceed 50mm. The motor is mainly used in medical, semiconductor, aviation, automotive and other fields, including valve brakes, Z axis grab and accurate position control for short distances, small precision replacement measuring instruments, vibration platforms, and active vibration reduction systems. The market mainly points to the medical, semiconductor, aviation and automation industries.

Rectangular coil motor
Compared with the cylindrical coil motor, the rectangular coil motor produces less thrust, but its stroke is relatively long. Its thrust reaches 1000N and its effective stroke can reach 250mm. The rectangular coil motor can be used alone. It is an ideal product for the generation of X-Y axis motion, and its market mainly points to the semiconductor and micro-machine tool industry.

Flat ring motor
Compared with the rectangular coil motor, the flat coil motor has a relatively short stroke in the same volume, but its advantage is that the height is lower. The thrust is up to 500N and the stroke is up to 25mm. The flat series is an ideal product for producing short-stroke X-Y sports. Its market mainly points to the semiconductor and micro-machine tool industry.

Swing coil motor
The swing ring motor adopts the technology of the rectangular series products and bends the rectangular series products to form a certain angle positioning system to meet the high performance angle swing. The RS series can provide an effective swing angle of 90 degrees and a torque of 50N-m. Swing ring motor products are applied to mirror locators in laser technology, swing valve brakes, swing positioning systems, and flight controllers, involving the semiconductor industry, automation, aviation, and aerospace industries.
