Abstract: The aim of the invention is to improve the production, design, and effectiveness of rollers or roller motors. Said aim is achieved by using a plastic support unit for the individual magnets in order to produce a multipole motor that has a small diameter and can be integrated into a roller. Said plastic support unit can be unscrewed after being incorporated into a return tube. Additionally, a roller comprising an integrated roller motor (24) is cooled by means of an external or internal cooling device (25, 26) so as to increase constant torque. Furthermore, in order to reduce the design of rollers which have to be braked as well, a braking device is provided which can be integrated into the roller. And finally, in order to simplify contacting of the stator during the production thereof, a divisible arbor is provided which comprises corresponding contact supports on both parts of the arbor.

Abstract: A rotor for permanent magnet synchronous machines with a reduction in the stray flux transmitted through the rotor shaft includes substantially ring-shaped punched sheet metal plates with a central opening for receiving the rotor shaft, and a plurality of recesses arranged in the circumferential direction, wherein at least two permanent magnets can be inserted in each of the recesses. A corresponding intermediate sheet metal segment is arranged or can be arranged in each of the recesses between the permanent magnets. At least one of the recesses is shaped so as to form an air gap between the surface of the intermediate sheet metal segment that is oriented radially inwardly towards the center and an edge of the recess that is oriented radially outwardly from the center, when the permanent magnets are inserted radially towards the outside. The air gap aids in attenuating the stray flux.

Abstract: A method of producing a laminated core of a stator of an electric motor, includes at least one laminated core of a stator formed by stacked sheet-metal laminates, which have mechanical individual poles and of poles connected in the circumferential direction of the stator, at least one pole shank and at least one pole shoe facing a rotor. The sheet-metal laminates are configured with indentations and protrusions and, as a result, the sheet-metal laminates form the laminated core of the stator by interengagement of the indentations and protrusions. The mechanical poles of the laminated core of the stator have windings, and webs are provided between the poles to connect the connected mechanical poles in the circumferential direction. The axial set-up of the sheet-metal laminates of the laminated core of the stator has a predeterminable alternating succession of poles with a connecting web and poles without a connecting web.
