Abstract
The present invention relates to an EC motor assembly (1) having an electronically commutated, permanent magnet-excited DC motor (M) with an upstream commutation electronic unit (2) that is supplied with a DC link voltage (UZK) via a DC link (8). The DC link (8) can be connected directly to a solar cell generator (12) via a first voltage input (10) on one hand, and on the other, to a grid voltage (UM) via a controllable power supply unit (14) and a second voltage input (16). The DC link voltage (UZK) is variably specified based on a respective available photovoltaic voltage (UPV) of the solar cell generator (12). The power supply unit (14) can be regulated with respect to the output voltage thereof to adapt to the respective DC link voltage (UZK).
