Abstract
A method for operating a pump assembly, wherein the pump assembly has at least one first drive means for conveying a fluid and an electric motor for driving the first drive means, the electric motor comprising at least one stator and one rotor, the rotor being connected at least to the first drive means via a driveshaft. The electric motor draws power at least: i. in order to heat the rotor by means of induction; or ii. in order to drive the rotor, the driveshaft and the first drive means so that these components rotate about a common rotation axis at a speed of more than '' revolutions per minute.
