Abstract: According to an aspect there is provided a motor (1) for a personal care device (10). The motor (1) comprises: a stator (2) comprising a stator surface; a rotor (3) comprising a rotor surface disposed opposite the stator surface; and a spacer (4) projecting between the stator surface and the rotor surface so as to define a minimum airgap between the stator (2) and the rotor (3). The spacer (4) is disposed on or at one of the rotor surface and the stator surface, and has a contact surface configured to engage with the other one of the rotor surface and the stator surface.
