Abstract

The motor has a circular cover (30) with a cylindrical flange with a permanent magnet (32) and a central shaft (31) engaging a bearing sleeve (121). A magnetically-conducting tube (12') fits on the outside of the bearing sleeve and carries a flat pole plate (10') with stamped-out tags (11') forming pole pieces. A circular coil (20) fits inside the pole pieces and additional pole pieces (11) on a baseplate (10) fastened to a substrate. The baseplate has a central tube (12) fitting outside the tube on the pole plate and supports a conductor plate (40) with electrical connections and a sensor (42).
