Stator for an electric machine, electric machine, stator cooling system, and method for cooling a stator

Stator for an electrical machine, which has a stator core with at least one stator groove in which at least two electrical conductors are arranged,

• wherein at least a part of the stator is produced by means of a method for additive manufacturing,
• wherein for a predetermined number of the electrical conductors in each case at least one cooling channel which can be supplied with a cooling fluid is formed;
• wherein at least two cooling channels, which are not formed by the same electrical conductor, are fluidically connected in parallel;
• and/or
• wherein at least a first and a further cooling channel group, in each of which the cooling channels of several electrical conductors can be supplied with cooling fluid in parallel to each another, are fluidically connected in series and/or in parallel to form separate circuits or one circuit.
