Abstract
A motor-compressor for a refrigerator includes a housing containing a lubricant and a reciprocating compressor driven by a direct-current electric motor having a disc-shaped rotor and stator. The stator is located between magnetic flux closing discs of the rotor and carries electronically commutated drive coils. Goniometric indicators detect the position of the rotor and cause signals to be applied to an alternating current generator which modulates a bridge circuit to provide current flux for driving the rotor.
