The invention discloses an efficient heat dissipation voice coil motor, which comprises a motor stator and a motor rotor, and is characterized in that the motor rotor is arranged in the motor stator;the whole motor stator is of a cylindrical structure and is hollow, one side of the motor stator is open, a connecting cylinder is arranged on the open side, and an end cover is arranged at the otherend. A permanent magnet is arranged in the motor stator, a coil is wound on the motor rotor, and the coil is connected with a power supply through a wire. A guide rod is arranged at one end of the motor rotor and penetrates out of the connecting cylinder; a heat dissipation shell is arranged outside the motor stator, the heat dissipation shell is installed on the motor stator through a heat conduction block, a heat absorption ring is arranged between the permanent magnet and the inner wall of the motor stator, and the heat absorption ring is fixedly connected with the heat conduction block; according to the invention, the heat conduction ring is arranged to absorb heat in the motor stator and transmit the heat to the heat dissipation shell, so that the heat is transferred to the outside and to be dissipated.
Description
technical field [0001] The invention relates to the technical field of voice coil motors, in particular to a voice coil motor with high heat dissipation. Background technique [0002] A voice coil motor is a special form of direct drive motor. It has a simple structure, small size, high speed, and high speed. In recent years, with the improvement of performance requirements for high-speed and high-precision positioning systems and the rapid development of voice coil motor technology, voice coil motors are not only widely used in precision positioning such as magnetic disks and laser discs. In the system, it is also widely used in many different forms of high acceleration and high frequency excitation. [0003] The principle of the voice coil motor uses the current to flow in different directions in the magnetic field, and the direction of the generated force also changes accordingly, thereby moving; now the general voice coil motor mover will generate a lot of heat after a ...
