Integrated electric motor drive and dry runner centrifugal pump assembly with such an integrated electric motor drive

An integrated electric motor drive comprising:

• rotatable parts comprising a drive shaft and a rotor, wherein the drive shaft extends along a rotor axis and the rotor is mechanically coupled to the drive shaft;
• and
• static parts comprising a stator and power electronics for controlling an electric current through the sta-tor, wherein the integrated electric motor drive further comprises a liquid cooling system comprising a closed liquid cooling circuit and a liquid coolant agitator, wherein the closed liquid cooling circuit is filled with liquid coolant being in direct or indirect thermal contact with the stator and/or the power electronics, wherein the liquid coolant agitator is arranged and configured to circulate the liquid coolant along the closed liquid cooling circuit, wherein the liquid coolant agitator is mounted within the closed liquid cooling circuit to be rotatable about the rotor axis, and wherein the liquid coolant agitator is magnetically coupled to one or more of the movable parts.
