Abstract
A micromotor includes a magnetic rotor fixed on a shaft. A stator has at least one winding. Bearings are provided to rotatably support the shaft relative to the stator. The bearings include a first silicon substrate having a V-groove, with a pair of bounding walls. Both bounding walls extend parallel to the shaft. The bearings also include a second silicon substrate having a third bounding wall which also extends parallel to the shaft. The shaft is positioned relative to the stator by the three bounding walls.
