Document Type and Number:
WIPO Patent Application WO/2023/051815
Kind Code:
A1
Abstract:
Provided in the present application are a power-off protection electric motor and an actuator. The power-off protection electric motor comprises: a stator base (1), a rotor top cover (15) and a moving flange (7), wherein the moving flange (7) is axially and movably mounted on the stator base (1), and the rotor top cover (15) rotationally matches and axially positions the moving flange (7); an electromagnetic coil (11) is mounted on the stator base (1), a first friction portion (12) is arranged at the top end of the stator base (1), a second friction portion (13) opposite the first friction portion (12) is arranged at the bottom of the rotor top cover (15), and an elastic member (4) is also arranged between the stator base (1) and the moving flange (7); and the rotor top cover (15) or the moving flange (7) is further provided with a traction magnetic member (14) cooperating with the electromagnetic coil (11) to provide a force for separating the first friction portion (12) from the second friction portion (13).
