Title:
MINIATURE MOTOR ENABLING MULTI-DIMENSIONAL RECIPROCATING MOVEMENT
Document Type and Number:
WIPO Patent Application WO/2020/244275
Kind Code:
A1
Abstract:
Disclosed is a miniature motor enabling a multi-dimensional reciprocating movement, the motor comprising a cylindrical housing. A stator and a rotor are provided within the housing. The rotor comprises a rotating shaft disposed along an axial direction of the housing. An axial actuating iron core and a circumferential actuating iron core are installed on the rotating shaft. The stator comprises a cylindrical coil frame disposed coaxially with the rotating shaft. The coil frame is located between the axial actuating iron core and the circumferential actuating iron core, and coils are wound on the coil frame along a circumferential direction thereof. A magnetic axial actuating assembly and circumferential actuating assembly are provided within the housing correspondingly to the axial actuating iron core and the circumferential actuating iron core, respectively. The present invention enables the axial actuating iron core and the circumferential actuating iron core to generate periodically-changing inductive magnetic poles when a periodically changing energization is applied to the coils, and the inductive magnetic poles interact with intrinsic magnetic poles of the corresponding axial actuating assembly and circumferential actuating assembly, thereby driving the rotating shaft to perform a composite axial and circumferential reciprocating movement in a periodical manner.
