SUPERCHARGER MANUFACTURING METHOD AND SUPERCHARGER

摘要

A method of manufacturing a turbocharger which allows easy performance of assembly operations of a motor rotor and a stator in a motor overhang structural turbocharger is provided. In a method of manufacturing a turbocharger in which a motor is attached to an end portion of a rotor shaft (15) connected to a compressor portion, the motor includes a cylindrical housing (33), a stator (32) accommodated inside the housing (33), and a motor rotor (31) which is connected to an end portion of the rotor shaft (15) with permanent magnets rotating inside the stator (32), and the method includes a rotor installation step of connecting and attaching the motor rotor (31) to the rotor shaft (15), a housing installation step of fixing and supporting the housing (33) coaxial to the rotor shaft (15), and a stator installation step of using the housing (33) as a guide, and inserting the stator (32) into the housing (33) such that the stator (32) does not directly come into contact with the motor rotor (31) to incorporate the stator (32) into the housing (33).
