Since its establishment, Kunshan Tongmao Electronics Co., Ltd. has been committed to the research, development, and of voice coil motors. Tongmao's voice coil motors are divided into five categories: cylindrical, rectangular, flat, swing type, and shaft type, with cylindrical voice coil accounting for more than 60%. 

      For cylindrical voice coil motors, Tongmao has made further classifications, namely, moving coil cylindrical voice coil motors and moving magnet voice coil motors. The moving coil cylindrical voice coil motor refers to the part where the magnet is fixed and the coil moves; the moving magnet cylindrical voice coil motor adopts a structure where coil is fixed and the magnet can move. It has a larger output and a higher output efficiency, and at the same time, it has a lower hysteresis loss at high and a faster step response; the moving magnet cylindrical voice coil motor has a wider working bandwidth and avoids the problem of cable dragging. Long-term movement will not cause cable breakage So, how to distinguish between Tongmao's moving coil cylindrical voice coil motor and moving magnet cylindrical voice coil motor? In fact, it can be distinguished from its. For example, TMEC0030-010-000, TMEC represents the cylindrical voice coil motor, 30 represents the peak force of 0N, 10 represents the travel of 10mm, and 000 represents the serial number. Tongmao's moving coil cylindrical voice coil motor moving magnet cylindrical voice coil motor are distinguished in the serial number. Usually, the serial number of the moving magnet cylindrical voice coil motor is 00M. Seeing the letter M the serial number represents the moving magnet cylindrical voice coil motor, and without M is the moving coil cylindrical voice coil motor. For example, TMEC0020-01-00M is a moving magnet cylindrical voice coil motor. 

      Kunshan Tongmao Electronics Co., Ltd. has launched hundreds of standard models of voice coil motors date, all of which adopt European and American technical standards and processing technology, and can achieve import substitution of similar products. Welcome to pay more attention.
