Motor and oral cleaning device

Abstract

The present disclosure relates to a motor and an oral cleaning device. The motor according to the present disclosure includes a rotor shaft, a rotor member, a stator assembly, and two groups of magnets, wherein the rotor member is fixedly arranged on the rotor shaft and has two winding mounting arms extending in opposite directions in a radial direction of the rotor shaft, and the winding mounting arms are configured to mount windings; the stator assembly is arranged around the rotor member; the two groups of magnets are arranged on the stator assembly and correspond to the two winding mounting arms respectively, and each group of magnets includes two magnets with opposite magnetic properties; in at least one plane perpendicular to a rotation axis of the rotor shaft, a central angle α of central lines of the two magnets in the same group ranges from 40° to 50° with an intersection point of the rotation axis and the plane as a circle center.
