Compressor arrangement with integrated motor

A cooling/refrigerating system comprising a rotary compressor arrangement comprising:

• a stationary member centered at a shaft axis and a rotary member rotating around the stationary member;
• the stationary member and the rotary member being inside a hermetically sealed inner volume within the rotary compressor arrangement;
• a stator with a winding arrangement generating an electromagnetic force inside the stator, the stator being arranged outside of the hermetically sealed inner volume;
• a plurality of magnets directly attached to the rotary member and facing the winding arrangement in the stator such that the rotary member is entrained in rotation by a rotating electromagnetic field from the stator;
• a rolling member eccentrically arranged with respect to the stationary member such that at least one compression chamber is created between them;
• an upper plate and a lower plate arranged at an upper part and a lower part, respectively, of the rolling member, sealing the at least one compression chamber created between the stationary member and the rolling member;
• and
• at least one segment element arranged between the upper and lower plates to allow a tight sealing of the at least one compression chamber and the movement of the rolling member, the at least one segment element comprising a low friction material.
