Voice coil motor heating problems facing the way, whether it is voice coil motor or rotary motor, servo motor, there will be fever in the course of the problem, Tongmao voice coil motor designed to fully consider this issue.
       In fact, we say that the voice coil motor heating problems, mainly from the motor's own acceleration and deceleration, if the acceleration and deceleration required current can be maintained at the motor and driver continuous current, then there will be no serious heat problems .
       On the other hand, if there is a short period of high current during acceleration and deceleration, it is important to consider the equivalent thrust at the brewing stage of the exercise planning and add the time to suspend or wait for exercise according to the actual demand.
       In addition, if the voice coil motor continues to push the work of the actual current exceeds the above continuous current, it is also necessary to consider the heat problem. Under normal use, the structure of the iron core linear motor is more conducive to heat dissipation, while the non-iron core motor coil does not have enough space for heat dissipation. Therefore, in designing the motion structure, the heat dissipation characteristics of the linear voice coil motor structure must be considered.
       The voice coil motor is a special form of direct drive motor that converts electrical energy directly to linear motion mechanical energy without the need for any intermediate converter gear. The principle is: in a uniform air gap magnetic field into a cylindrical winding, the winding electromagnetically energized to drive the load for linear reciprocating motion, changing the current strength and polarity, you can change the size and direction of the electromagnetic force. Therefore, the voice coil motor movement can be straight or rotated. It has the advantages of high response, high speed, high acceleration, simple structure, small volume, good force characteristics and convenient control. The voice coil motor has no friction during movement, therefore, the heating problem is made cleverly and rationally.
