  • Refrigeration system having a compressor driven by a magnetic coupling
    Patent number: 11867181
    Abstract: A refrigeration system includes a compressor having a hermetically sealed housing and a compression mechanism which is positioned inside the housing; a condenser which is fluidly connected to the compressor; an evaporator which is fluidly connected between the condenser and the compressor; a magnetic coupling having a drive coupling half positioned outside the housing and a driven coupling half positioned inside the housing and separated from the drive coupling half by a separation wall portion of the housing; and a fluid conduit for communicating a portion of liquid refrigerant from the condenser to an inside surface of the separation wall portion. During operation, the liquid refrigerant from the condenser is evaporated on or adjacent the inside surface of the separation wall portion to thereby dissipate heat generated by magnetically induced eddy currents in the separation wall portion.
    Type: Grant

  • Magnet to magnet couplings and drives
    Patent number: 10305360
    Abstract: A balanced magnetic rotor assembly is disclosed. The balanced rotor assembly including a driver rotor assembly having a first driver rotor assembly and a second driver rotor assembly arranged about a rotational axis and being spaced apart from each other a distance along the rotational axis, and a load rotor being arranged about the rotational axis and arranged between the first driver rotor and the second driver rotor.
