Abstract: A bent conductor segment (1a, 1b, 1c) for a stator winding of a stator of an electric machine is formed from a bent metal wire and has at least one first straight section (10a, 10b, 10c) with a first free end (11a, 11b, 11c) and a second free end (13a, 13b, 13c). One of the free ends (11a, 11b, 11c, 13a, 13b, 13c) of the conductor segment (1a, 1b, 1c) comprises a hard solder (2a, 2b, 2c) cohesively connected to said free end (11a, 11b, 11c, 13a, 13b, 13c).

Abstract: A method is provided for balancing rotors (10) of electrical machines. Each rotor (10) has a shaft (11) and at least one laminated core (12) is arranged on the shaft. The method includes providing blanks (13) with a length (l) that is smaller than an outside diameter (d) of the laminated core (12) of the rotor (10). A magnitude and orientation of an initial unbalance of the rotor (10) then is ascertained. A recess (15) then is made in each blank (13) spaced from the center of gravity by a distance depending on the magnitude of the ascertained initial unbalance. The blank (13) is mounted by fitting the recess (15) on the shaft (11) of the rotor (10) and mounting the processed blank (13) on the rotor (11) in an angular position that is dependent on the orientation of the ascertained initial unbalance.

Abstract: A drive unit (1) has a housing (2) and an output-side element (3). The housing (2) has at least two webs (8) that lie opposite one another and that project from the housing (2) in a manner so that the webs (8) are spaced apart from one another. The webs (8) are configured to fasten the housing (2) to a mounting unit (7).

Abstract: A method for balancing rotors (10) of electrical machines, where each rotor (10) has a shaft (11) and at least one laminated core (12) arranged on the shaft.
