The difference and relation between voice coil motor and linear motor. Kunshan with Mao Electronics Co. , Ltd. is a voice Coil Motor, Linear Motor R & D, production and sales of high-tech enterprises, brand chain enterprises. After more than 10 years of development, Tongmao voice coil motor and linear motor accounted for 39% of the domestic direct drive products market, has been able to achieve import substitution. What is the difference and connection between the voice coil motor and the linear motor? 

     The connection lies in: Tongmao linear motor mainly includes three kinds of linear motor with no iron core and u-shaped slot, flat linear motor with iron core and tubular linear motor, among which tubular linear motor is also called cylindrical voice coil motor, that is to say, voice coil motor is a kind of linear motor. 

     The difference lies in: one is the difference in stroke, with Mao introduced the linear motor stroke can be extended, and voice coil motor is a short stroke, small size of the motor; two is the difference in structure, a voice-coil motor is energized by a magnetic field. The force is proportional to the current applied to the coil. A voice coil motor based on this principle can move in a straight line or in an ARC. 2) linear motor is a kind of transmission device which can directly convert electric energy into linear motion by expanding closed magnetic field into open magnetic field without any intermediate conversion mechanism. Its structure can be seen as a rotating motor along the radial cut, and the motor's circumference into a straight line and formed. 

      As mentioned above, coreless u-slot linear motor, cored flat-plate linear motor and tubular linear motor (cylindrical voice coil motor) are the main products of Tongmao. In fact, Tongmao intelligence also sells other types of voice coil motor, including rectangular voice coil motor, flat voice coil motor, swing voice coil motor and shaft voice Coil Motor, are based on the development and production of cylindrical voice coil motor.
