Title:
VOICE COIL ELECTRIC MOTOR, AND CONTROL METHOD AND CONTROL APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/179201
Kind Code:
A1
Abstract:
Provided are a voice coil electric motor (100), and a control method and control apparatus therefor. The voice coil electric motor (100) is composed of an inner coil module and an outer coil module, wherein the inner coil module is arranged within the outer coil module, and an air gap (150) allowing the inner coil module to move is formed between the inner coil module and the outer coil module. The control method for a voice coil electric motor (100) comprises: driving an outer coil module of a voice coil electric motor (100) to generate an outer coil electromagnetic force; determining an inner coil current instruction according to a desired force instruction, and force feedback information sent by an actuating mechanism of the voice coil electric motor (100); according to the inner coil current instruction, driving an inner coil module of the voice coil electric motor (100) to generate an inner coil electromagnetic force; and enabling the actuating mechanism (140) to generate an electric motor action force according to the outer coil electromagnetic force and the inner coil electromagnetic force.
