Abstract: An electric motor includes a stator having a stator lamination stack and electric conductors. The stator lamination stack has a plurality of stator laminations, wherein the stator lamination stack has axial slots. The stator lamination stack has a plurality of positioning disks, and the positioning disks have leadthroughs. The electric conductors are arranged in the slots, being passed through the leadthroughs, wherein the leadthroughs have positioning regions for positioning the electric conductors. Also described is a method for operating an electric motor and a method for producing an electric motor.

Abstract: A canned motor has a stator which has a laminated core and a winding with winding heads which project out of the laminated core on end sides of the laminated core. A rotor is mounted rotatably with respect to the stator. A can is arranged between the stator and the rotor. An end plate bears against an end side of the laminated core and has recesses for leading through the winding. A supporting ring is arranged concentrically with respect to the can on the outer side of the can in the region of the winding heads. The end plate and the supporting ring are configured as a single-piece supporting end plate.

Abstract: An electrical drive device includes a stator and a rotor. The stator has a main body and windings of an electromagnetic coil. The main body has clearances, and the windings are at least partially arranged in the clearances. The stator has two coolant inlets and a coolant collecting device with a coolant outlet. The coolant inlets are in fluidic connection with the coolant outlet by way of the clearances.

Abstract: A rotor for an electric motor has a shaft and a rotor laminated core connected to the shaft. A coolant duct is formed in the rotor in order to enable coolant to flow through the coolant duct. The coolant duct has a first portion, which runs at least in regions in the rotor laminated core. The rotor laminated core has a sleeve on the outer circumferential surface in order to avoid coolant escaping at the outer circumferential surface of the rotor laminated core. In a method for producing a rotor, a material having glass fibers or carbon fibers and a resin are applied to the rotor laminated core, and the resin is subsequently cured in order to produce the sleeve.

Furthermore, a method for manufacturing a stator coil, a stator coil having a coil segment according to the present invention, a machine having a stator coil according to the present invention, and a vehicle having a machine according to the present invention.

Abstract: A method for producing an electric drive machine, including the steps of providing a stator having a cavity for the introduction of a rotor and introducing a hardenable seal into the cavity in contact with the stator and then hardening the seal.

Abstract: 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.

Abstract: 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.
