Electric oscillation motor

摘要

The oscillation motor has a rotor (16) provided with a magnet (18) with at least 2 poles in the radial direction, enclosed by a winding frame with at least 2 winding parts (202a,202c) extending outwards from the periphery of the rotor magnet and spaced from one another in the peripheral direction. The entire winding frame is made of a non-magnetic material, with each of the winding parts directly wound with a winding wire to provide at least 2 drive coils (19a,19c), for controlling the oscillation of the rotor over a given angular range.
