A MICROMOTOR AND A METHOD OF MANUFACTURING A MICROMOTOR

摘要

The micromotor (1) comprises a magnetic rotor (2) which is fixed on a shaft (3). The micromotor (1) further comprises a stator (4) having at least one winding, in this case a coil (5). Bearing means are provided to support the shaft (3) rotatably relative to the stator (4). The bearing means comprise a first silicon substrate (10) which has a V-groove (11), with a first bounding wall (11a) and a second bounding wall (11b). Both bounding walls (11a and 11b) extend parallel to the shaft (3). The bearing means further comprise a second silicon substrate (20) with a third bounding wall (21) which also extends parallel to the shaft (3). The shaft (3) is positioned relative to the stator (4) by the bounding walls (11a, 11b and 21).
