Abstract: A stator is provided for an electric machine. The stator includes a plurality of teeth which are each designed such that a winding can be arranged on them. The teeth are at a first angle in relation to the longitudinal axis in a first region which extends in the axial direction of the stator. The teeth are at a second angle, which differs from the first angle, in relation to the longitudinal axis in a second region which extends in the axial direction of the stator. A third region in which the teeth are electrically insulated is arranged between the first region and the second region.

Abstract: A method of shift control for an automatic transmission of vehicle power train, having a permanent brake between a drive motor and a final drive, in which current vehicle-specific, road-specific and driver-specific operating parameters, topographical data relating to an upcoming stretch of road ahead of the vehicle are determined while driving, and from which a tractive resistance value for the upcoming stretch of road is determined, and control commands for thrust downshifts and/or upshifts are derived and implemented, within the transmission, during a thrust operation depending upon the tractive resistance value. This is achieved in that the maximum permanent braking force curves that are possible for the upcoming stretch of road, in the currently engaged gear, and each adjacent gear is determined based on the current traveling and engine speeds and analyzed to derive control commands for a thrust downshift and/or upshift in relation to the tractive resistance value.

Abstract: A portable work apparatus has a main unit and a work tool. The main unit is carried by the user via a strap. The strap has a fastening section which is secured to the main unit via a fastening element. The fastening section is held between a pressure surface of the fastening element and a fastening surface formed on the main unit. To prevent twisting of the strap when the fastening element is secured, provision is made for the fastening surface to be formed with a structure that increases the friction coefficient. The structure interacts with a bearing surface, facing the fastening surface, of the fastening section such that the fastening section, which is held in a clamped manner between the pressure surface of the fastening element and the fastening surface of the main unit, is prevented from rotating relative to the main unit.
