Planar magnetic motor and magnetic microactuator with such a motor

摘要

The winds are wound and connected between one another in order to combine the magnetic flows generated across the magnetic poles (111,121). The magnetic planar motor can be incorporated in a magnetic micro-activator which incorporates also a mechanical unit (200) with mobile contact, including a support frame (210) placed on the surface of the ferro-magnetic substrate through the intermediary of a spacer, and a flexible sheet (240) arranged essentially parallel to the surface of the substrate. An extremity of the flexible sheet is fixed on the support frame and the sheet also supports a core (230) of ferro-magnetic material and a mobile contact (220) forming part of the core faces a fixed contact (150) provided on the surface of the substrate.
