Described is a method for producing a stator, in particular for electric motors. In a first step, a plurality of flexible electrical conductors are combined to form a conductor bundle. In a second step, two end regions of the conductor bundle are pressed in such a way that a central region of the conductor bundle formed between the two end regions remains flexible. Also described is a corresponding stator.

A device for sealing off multiple grooves of a stator of an electric drive machine with respect to a rotor of the electric drive machine. The device includes a seal which is able to be inserted simultaneously into the multiple grooves, wherein the seal is designed as an electrical insulator. The seal is designed to seal off the grooves with respect to the rotor. Windings of an electrical coil are able to be arranged in the grooves. The seal is of integral or unipartite design.

A method for operating a synchronous machine having a rotor, comprising the following features: the synchronous machine is modelled, with respect to the rotor, as a two-phase system with a direct-axis current and a quadrature-axis current, rotor losses of the synchronous machine, which rotor losses occur in the rotor, are numerically described by an evaluation function of the first direct-axis current, of the quadrature-axis current and of a specified rotation speed of the synchronous machine, and, on the basis of the evaluation function, the direct-axis current and the second quadrature-axis current are controlled for the specified rotation speed and a required torque in such a way that the synchronous machine outputs the required torque and the rotor losses are low and a corresponding synchronous machine, a corresponding computer program and a corresponding storage medium.
