Abstract

A domestic refrigeration appliance includes an insulated body with a coolable container delimiting a coolable space for food, a refrigerant circuit having a coolant and a compressor for cooling the space, and an electronic control apparatus and an electric drive with a three-phase AC synchronous motor and a control element or inverter for activating the motor. The compressor includes a chamber with an inlet and with an outlet, a piston mounted displaceably within the chamber, a crankshaft and the motor. The motor has a number of pole pairs greater than 1, a stator and a rotor mounted rotatably relative to the stator and coupled to the piston by the crankshaft. During compressor operation, the motor causes the piston to reduce the size of a volume enclosed by the compressor chamber and the piston to compress the coolant. A method for operating a domestic refrigeration appliance is also provided.
