Title:
MOTOR DRIVING DEVICE, GIMBAL STABILIZING SYSTEM, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/266897
Kind Code:
A1
Abstract:
A motor driving device (100), comprising a motor (10), a locking member (20), a first memory alloy wire (30), and a reset member (40); the locking member (20) is used for locking a rotor component (12) of the motor (10) so as to prevent the rotor component (12) from rotating relative to a stator component (11) of the motor (10); the first memory alloy wire (30) is mechanically coupled to the locking member (20), and the length of the first memory alloy wire (30) is shortened when the first memory alloy wire (30) is energized, thus driving the locking member (20) to slide from a first position to a second position; the reset member (40) is mechanically coupled to the locking member (20), and the reset member (40) can move the locking member (20) from the second position to the first position; and when the motor (10) is powered off, the locking member (20) can lock the rotor component (12) at a preset angle position, the preset angle position being outside of the preset working angle range of the rotor component (12). The present invention further relates to a gimbal stabilizing system (1000) and a control method.
