Motor stator with loose laminations

摘要

A motor stator is constructed from loose laminations which are aligned and secured to the compressor housing at the time of assembling the compressor unit. The loose lamination stator is first attached to the compressor housing to initially locate the stator. A solid sizing mandrel is pushed through the rotor accommodating bore to remove any burrs and initially size the bore. An expanding mandrel is then positioned within the rotor accommodating bore and expanded to finalize the sizing of the bore and the alignment with the compressor housing. Once the final size and alignment have been achieved, the stator is secured to the motor housing.
