  • the first coolant line an inner diameter of 2 to 4 mm and / or the second coolant line has an inner diameter of 5 to 7 mm.
  • the exact inner diameter depends - as well as that of the outlet openings - from different circumstances, in particular the viscosity of the coolant used, the delivery volume of the coolant pump, the flow resistance of the windings, the dissipated power loss, and the like.
  • the coolant flowing through the coolant line is preferably a nonconductive cooling fluid with non-corrosive properties, for example a heat-resistant oil, in particular silicone oil.
