The invention relates to a device (10) for the incremental control of at least one first direct-current motor (12) for the cooling fan of a motor vehicle. Said device comprises a first (14) and a second current-limiting component (16), and a first (22), a second (24) and a third switching element (28). The inventive device is characterized in that the switching elements (22, 24, 28) connect the first (14) and the second current-limiting component (16) in such a manner that the cooling capacity of the cooling fan can be varied in at least four levels different from zero.

摘要:
An external rotor motor is disclosed, which features a stator (11) and a rotor (13) surrounding the stator (11) while leaving an air gap. A damper (16) made of an elastic material is arranged on the outside of the rotor (13) in order to dampen resonant rises in airborne sound, which is emitted by the rotor of the external rotor motor and by an assembly coupled to it. In the case of a rotor (13) that is designed to be pot-shaped, the damper (16) is preferably embodied as a damping cap (17), which surrounds the pot jacket (132) and at least partially covers the pot base (131) (FIG. 1).

The invention relates to a winding carrier (1) for the defined application of a coil winding, comprising: a winding section (2) for placing onto a cylindrical tooth component; a groove structure (3), which is arranged in at least one region of the winding section and extends transversely to the winding axis in order to receive a winding wire; wherein the groove structure (3) has a cross section having two mutually opposite, preferably flat side faces (7), which taper in the direction of a bottom face (6) of the groove structure (3).
摘要:
The invention relates to a method for producing a machine component (1) for an electrical machine, wherein the machine component (1) is formed with a magnetically conductive material, in which one or more magnetically nonconductive separating regions (4) are provided, wherein the separating region (4) is formed by the introduction of austenite-forming material during a melting process of the magnetically conductive material of the machine component (1), such that an austenitic structure is formed in the magnetically conductive material of the machine component (1).
摘要:
The invention relates to a stator in an electric motor comprising a plurality of teeth segments forming a stator ring, said teeth segments comprising outer yoke segments and radial support teeth. Connection elements are arranged on the peripheral front sides of the yoke segment and are offset in the direction of the radial outer side.
