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.

Abstract: The invention relates to an electric motor having a rotatably mounted rotor magnet and a stator enclosing the rotor magnet, said stator comprising at least three coil windings and a winding carrier, wherein coil axes of the at least three coil windings are disposed radially to an axis of rotation of the rotor magnet in various radial directions. The coil windings of the electric motor are designed so that a gap that is parallel to the axis of rotation of the rotor magnet extends between at least two adjacent coil windings, in which at least one media line extending in the longitudinal direction is provided.

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: Dental handpiece with an instrument section (1) for accepting a dental tool and with a second, hose section (2) which is capable of being detachably coupled to the instrument section and to which a media delivery line for the delivery of certain supply media for operation of the dental tool is capable of being linked, said dental tool being operated by a drive motor (3). The drive motor comprises a stator (9) and a rotor (5). The rotor (5) of the drive motor (3) is arranged in the instrument section (1) separate from the stator (9), the stator (9) of the drive motor (3) being arranged in the hose section (2). By virtue of the partial integration, in accordance with the invention, of the drive motor, the weight of the dental handpiece is diminished and the ease of handling of the dental handpiece is improved. In addition, higher working speeds of the dental tool can be achieved.

Abstract: Motorised handpiece, more particularly for used by dentists or dental technicians, the rotary movement of a motor being transmitted to a tool which can be clamped with the aid of a clamping mechanism. To this end, the rotary movement of the motor is transmitted via an integrally formed shaft to the clamped tool, both the motor and the clamping mechanism being mounted on this integrally formed shaft. As a result of the use of an integrally formed shaft, it is possible to dispense with superfluous ball bearings for mounting the shaft and no mechanical driver system is required in order to couple two separate shafts together, for example.
