Claims10
A motor compressor unit, comprising:
- a motor casing;
- a compressor casing attached to the motor casing;
- a compressor bundle that resides inside of the compressor casing and attaches to the motor casing and the compressor casing;
- and a plurality of fastened locations comprising a first fastened location at which the compressor bundle couples to the compressor casing in a first direction that is perpendicular to the longitudinal axis, a second fastened location at which the compressor casing couples to the motor casing in a second direction that is parallel to the longitudinal axis, and a third fastened location at which the compressor bundle couples to the motor casing in the second direction, wherein the compressor bundle includes an opening sized to couple a motor rotor and a compressor rotor through the at least one opening, and wherein one of the plurality of fastened locations comprises a weld.
