Miniature motor and housing fabrication

摘要

Method for fabricating an electric miniature motor, substantially comprising a housing assembly, a rotor assembly, a power transmission and bearing assembly and a second bearing assembly, wherein the housing assembly comprises a housing tube having a division extending in the axial direction over an entire length of the housing tube, comprising the following steps of a) inserting a cylindrical core having a defined outer diameter into the housing assembly; b) adjusting an inner diameter of the housing assembly to an outer diameter of the core; c) fixing the inner diameter of the housing assembly by fixing the housing tube in an area of the division; and d) removing the cylindrical core.

1. Method for fabricating an electric miniature motor, substantially comprising a housing assembly, a rotor assembly, a power transmission and bearing assembly and a second bearing assembly, wherein the housing assembly comprises a housing tube having a division extending in an the axial direction over an entire length of the housing tube, comprising the following steps of:
a) inserting a cylindrical core having a defined outer diameter into the housing assembly with magnets already mounted at an inner wall of the housing tube, the magnets including an inner diameter defining an inner diameter of the housing assembly; b) adjusting the inner diameter of the housing assembly to the outer diameter of the core; c) fixing the inner diameter of the housing assembly by fixing the housing tube in an area of the division; and d) removing the cylindrical core.
