摘要： A refrigerator fan device, comprising: a fan motor (10) which has a fan rotor (12) and which can be provided in an air duct between an air inlet (16), a refrigerator heat exchanger (15), and/or a refrigerator compressor (14) and an air outlet (18) on or in a refrigerator housing (20, 22), said fan motor (10) being connectable to a unit of the refrigerator, via electrical supply and/or control lines, wherein the fan motor (10) is realized as a brushless speed-controllable DC motor whose operating speed is or can be controlled as a function of an operating and/or used cooling space temperature signal of, the assigned or assignable refrigerator compressor.

摘要： The invention relates to a control apparatus for a refrigerator compressor having at least one two-phase AC asynchronous motor (K1, K2), having mains connection means (10) for connection to a preferably public voltage supply network Which nominally provides a mains AC voltage of between 85 V and 264 V, in particular between 100 V and 230 V, first voltage converter means (14) which are connected downstream of the mains connection means and are intended to generate an intermediate voltage, in particular an intermediate DC voltage, from the mains AC voltage, second voltage converter means (16-1, 16-2) which are connected downstream of the first voltage converter means and are intended to generate an output signal which is independent of a level and a mains frequency of the mains AC voltage, in particular has a constant voltage and/or frequency in periods, and is intended to control the refrigerator compressor with an AC voltage of a plurality of differently predefinable voltage levels, wherein the mains connection means are assigned voltage detector means (12) for capturing the mains AC voltage, the detector output signal from which can be evaluated by the second voltage converter means or control means (24) assigned to the latter for the purpose of generating a mains-voltage-dependent maximum value for a current of the output signal.
