MINIATURE ELECTRICAL MOTOR AND BLOWER

摘要

The invention relates a miniature motor comprising a permanent magnet rotor (6) arranged rotatably inside of a stator, magnetic fields of said stator being generated by energizing windings of the stator by an electronic commutator unit connected to the coils (4) of the stator, made as a one-piece stator/housing molding, in which thermoplastic material of the housing (1) is injected around the iron core (5) and coils (4). The invention relates further a miniature blower having an impeller being fixed on the shaft (7) of the rotor (6), said housing (1) of motor comprising a half of a two parts blower housing having at least an air-outlet canal (15) near to its perimeter, while the other part (3) of the blower housing has a coaxial inlet air-opening and covers said impeller (11) of the blower, where the two parts of the blower housing are fixed to each other at their perimeters.
