The production process can manufacture a motor carrier with a high precision screw thread.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a production process of a VCM motor component carrier. Background technique [0002] A VCM motor is a voice coil motor (Voice Coil Motor), which is a device that converts electrical energy into mechanical energy, and realizes linear and limited swing angle motion. A device that uses the interaction between the magnetic field from the permanent magnet steel and the magnetic poles in the magnetic field generated by the current-carrying coil conductor to produce regular motion [0003] At present, the voice coil motor mainly includes a casing, a base, a shrapnel, a carrier and a coil mounted on the carrier. The carrier is used to carry the lens, and the coil is wound on the carrier, so that after the coil is fed with electric energy, under the action of the magnetic field force of the magnet group, the two can simultaneously generate displacement along the axial directio...
